Descripción general

Description

SMBJ12CA-E3/52 is a bidirectional transient voltage suppressor (TVS) diode in the SMBJ surface-mount package. It protects 12 V systems from voltage transients and surges by clamping excess voltage in both polarities.
Key points:
- Configuration: Bidirectional (CA suffix)
- Package: SMBJ (DO-214AB)
- Rating: ~600 W peak pulse power (10/1000 μs) typical for the SMBJ series
- Working voltage: VRWM ~12 V; breakdown ~13–15 V; clamped voltage ~20–22 V at surge
- Suffix E3/52: vendor-specific packaging/lot/lead-finish code; refer to the datasheet for exact packaging and lead-free details
Common uses: automotive, industrial, and data/power lines requiring protection from inductive or automotive transients. For exact electrical characteristics, thermal limits, and packaging details, consult the specific datasheet from the supplier.

Features

Here are the typical features of the SMBJ12CA-E3/52:
- Bidirectional TVS diode for 12 V line surge protection (SMBJ package).
- Peak pulse power: ~600 W (10/1000 μs).
- Stand-off voltage: VRWM = 12 V; breakdown voltage ~13.3–15 V; clamping ~19–22 V (at IPP).
- Very fast response time (sub-ns to ns range).
- Wide operating temperature: typically -55 °C to +125 °C.
- Package: DO-214AB SMB surface-mount; RoHS-compliant; lead-free.
- Mounted protection suitable for automotive/industrial and telecom/appliance use.
- IEC61000-4-x surge/ESD robustness and general transients protection capability.
- Tape & reel (E3/52) for automated PCB assembly.
Note: exact VBR/Vclamp ranges can vary slightly by lot; refer to the datasheet for precise tolerances.

Package

It uses the SMB (DO-214AB) surface-mount package (the SMBJ series).

Pinout

- Pin count: 2 pins (two-terminal SMB/DO-214AB package)
- Function: Bidirectional transient voltage suppressor (TVS) diode used to clamp and absorb voltage surges, protecting circuits. For SMBJ12CA, the nominal working voltage is about 12 V (bidirectional protection).
