P0640SAL Alternative / Equivalent / Replacement - 64V TSS Thyristor Surge Protector SMB | YINT

If you are searching for a P0640SAL alternative, P0640SAL equivalent, or P0640SAL replacement, YINT Electronics provides a direct-compatible substitute for the Littelfuse P0640 series thyristor surge protector. The device is designed for telecom and data interface protection, helping safeguard circuits against transient overvoltage events.

1. Product Overview

The P0640SAL is a 64V thyristor surge suppressor (TSS) in the SMB package. It protects telecom, Ethernet, and RS-485 interfaces from lightning and transient surges. The device has a 58V minimum stand-off voltage, 77V maximum switching voltage, and handles 150A surge current on 8/20us waveforms.

Engineers looking for a P0640SA equivalent for Littelfuse or BrightKing can specify YINT's P0640SAL. It delivers low capacitance of 40pF for high-speed data lines and holds current of 120mA minimum for stable reset after a surge event.

8. FAQ

Q1: Is YINT P0640SAL a direct replacement for Littelfuse P0640SA?
A: Yes. Same 64V TSS class with identical surge ratings in SMB package.

Q2: What is the difference between TSS and TVS diodes?
A: TSS is a thyristor that latches during surge and resets after current drops, while TVS clamps voltage continuously.

Q3: What is the surge capability of P0640SAL?
A: 150A on 8/20us and 45A on 10/1000us waveforms.

Q4: Is P0640SAL suitable for high-speed data lines?
A: Yes. 40pF maximum capacitance supports Ethernet and RS-485 signaling.

Q5: What is the holding current?
A: 120mA minimum, ensuring the device resets after the surge current falls.

Q6: Does YINT provide free samples?
A: Yes. Contact YINT with your project details.
