Descripción general

Description

SMCJ28CA is a surface-mount transient-voltage-suppressor (TVS) diode in a DO-214AB package. It protects circuits from high-voltage transients by remaining nonconductive until the surge exceeds its breakdown, at which point it clamps the voltage to a safe level. It’s suited for 28V-rated systems (e.g., 24–28V rails and lines) and is used across power supplies and data lines to guard against spikes and ESD. The “CA” suffix denotes the specific variant of the 28V SMCJ family (polarity/ratings vary by manufacturer), so check the datasheet for exact electricals. Typical characteristics (manufacturer dependent) include a standoff around 28V, breakdown in the low-30V range, and clamp in the mid-40V range for short surges, with a high peak-pulse-power capability over short time scales (10/1000 µs). In short: a compact, high-speed surge protector for 28V circuits.

Features

Here are concise features of the SMCJ28CA:
- Bidirectional TVS diode (suffix CA) for 28 V systems
- Package: SMC (DO-214AB)
- Peak pulse power: 1500 W (10/1000 µs)
- Working standoff voltage: ~28 V
- Wide operating temperature: typically -55°C to +150°C
- Fast, rugged surge protection with low leakage at rated voltage
- RoHS compliant; lead-free
- Suitable for protecting 28 V lines in automotive, telecom, and industrial equipment

Package

SMCJ28CA uses the SMC package (DO-214AB) – a surface-mount, high-power TVS diode package.

Pinout

- Pin count: 2 terminals (DO-214AB SMC package)
- Function: Transient Voltage Suppressor (TVS) diode used to protect circuits from voltage transients; clamp voltage on a line with a nominal stand-off around 28 V.

Manufacturer

- Manufacturer: Littelfuse, Inc.
- What kind of company: An American multinational that designs and manufactures electrical protection devices, including fuses and transient-voltage-suppressor (TVS) diodes.

Application

SMCJ28CA is a 28 V TVS diode used to clamp transients on 28 V systems. Typical applications:
- Automotive 24–28 V power nets (load dumps, inductive spikes)
- Industrial controls and motor drives
- Power supplies and DC-DC converters
- Telecom/data interfaces (CAN, RS-485, USB, Ethernet) protection
- Solar/renewable power systems and battery backups
- Any 28 V line requiring ESD and surge protection for sensitive electronics

Equivalent

SMCJ28CA is a 28 V bidirectional TVS diode in the SMC (DO-214AB) package, about 600 W peak pulse power. Equivalents are other 28 V bidirectional TVS diodes in the SMC package from major vendors. Examples: Vishay’s SM CJ28CA, Littelfuse’s SMCJ28CA, and ON Semiconductor/ST equivalents with the same voltage rating and CA suffix. For exact cross-references, use distributor tools (Digi-Key/Mouser) to match Vbr, Ipp and package.
