Understanding the Technical Specifications of SMBJ70CA-TR TVS Diodes

TVS (Transient Voltage Suppression) diodes, such as the SMBJ70CA-TR, play a crucial role in protecting electronic circuits from voltage spikes and electrostatic discharge (ESD). Understanding their technical specifications is essential for selecting the right component for your application. Let's dive into the key specifications of the SMBJ70CA-TR TVS diode and what they mean for your projects.

1. Breakdown Voltage (V_BR)

The breakdown voltage is the voltage at which the diode starts to conduct in reverse. For the SMBJ70CA-TR, the breakdown voltage range is typically between 77.8V and 95.7V. This means that when the voltage exceeds this range, the diode will begin to conduct, clamping the voltage to a safe level and protecting the circuit.

2. Stand-off Voltage (V_R)

The stand-off voltage is the maximum voltage that can be applied to the diode without it conducting. For the SMBJ70CA-TR, the stand-off voltage is 70V. This is the normal operating voltage below which the diode remains inactive. It’s crucial to ensure that the operating voltage of your circuit does not exceed this value.

3. Peak Pulse Current (I_PP)

The peak pulse current is the maximum current the diode can handle during a transient event. The SMBJ70CA-TR can withstand a peak pulse current of 1.3A (10/1000µs waveform). This parameter is vital for understanding the diode’s capacity to handle sudden surges and is a key factor in ensuring the protection of your circuit.

4. Clamping Voltage (V_C)

The clamping voltage is the voltage to which the diode clamps the transient event. For the SMBJ70CA-TR, the clamping voltage is 113V at a peak pulse current of 1.3A. This value indicates the maximum voltage your circuit will experience during a transient event, ensuring it remains within safe limits.

5. Power Dissipation (P_PP)

Power dissipation is the maximum power the diode can dissipate. The SMBJ70CA-TR has a peak pulse power dissipation of 600W (10/1000µs waveform). This parameter helps determine the diode’s ability to handle power surges without being damaged.

6. Response Time

The response time of a TVS diode is the time it takes to respond to a transient event. The SMBJ70CA-TR has a response time of less than 1 picosecond. This ultra-fast response ensures immediate protection for sensitive electronic components from voltage spikes.

7. Capacitance

The capacitance of a TVS diode affects the signal integrity in high-speed circuits. For the SMBJ70CA-TR, the capacitance is typically 150pF at 1MHz. Lower capacitance is preferred for high-frequency applications to avoid signal degradation.

8. Packaging

The SMBJ70CA-TR is packaged in an SMB (DO-214AA) package. This surface-mount package is suitable for automated assembly processes and offers a compact form factor for space-constrained applications.

9. Polarity

The SMBJ70CA-TR is a bidirectional TVS diode. This means it can protect against both positive and negative voltage transients, making it versatile for various applications where bidirectional protection is required.

10. Operating and Storage Temperature Range

The operating temperature range for the SMBJ70CA-TR is from -55°C to +150°C, and the storage temperature range is also -55°C to +150°C. This wide temperature range ensures reliable performance in diverse environmental conditions.

11. Qualification and Compliance

The SMBJ70CA-TR TVS diode complies with industry standards and qualifications, ensuring high reliability and performance. It meets the requirements of IEC 61000-4-2 (ESD) and IEC 61000-4-4 (EFT) standards, making it suitable for robust ESD and surge protection.

Conclusion

Understanding the technical specifications of the SMBJ70CA-TR TVS diode is crucial for ensuring the protection and reliability of your electronic circuits. By carefully considering parameters such as breakdown voltage, stand-off voltage, peak pulse current, clamping voltage, power dissipation, and response time, you can select the right TVS diode for your application. Additionally, factors like capacitance, packaging, polarity, and temperature range are important to ensure optimal performance and compatibility with your design requirements.
