Pinout
The 1SMB5938BT3G is a 3-pin surface-mount transient voltage suppressor (TVS) diode in an SMB package.
Pin Functions:
1. Anode (A) – Connects to the protected circuit.
2. Cathode (K) – Connects to ground.
3. No Connection (NC) – Unused pin for mechanical stability.
Function:
- Protects circuits from voltage transients (ESD, surges).
- Clamps excessive voltage to a safe level (standoff voltage: 9.2V, breakdown voltage: 10.3V).
Package: SMB (DO-214AA).
Polarity: Unidirectional (conducts only in reverse bias).
