Overview

Description

SMBJ28CA-TR is a bidirectional transient-voltage-suppressor (TVS) diode in an SMB package (DO-214AA). It protects circuits from high-voltage transients on lines up to about 28 V. The CA suffix indicates bidirectional operation; -TR means tape-and-reel packaging for automated assembly. Key specs (typical): ~600 W peak pulse power (10/1000 µs), Vrwm around 28 V, clamping voltage dependent on surge current, and very low off-state leakage with a few pF of capacitance. Applications include protecting automotive, telecom, power-supply, and data lines and rails from ESD and surges. For exact numbers and tolerances, consult the manufacturer’s datasheet.

Features

Here are the typical features of the SMBJ28CA-TR:
- Bidirectional transient voltage suppressor (TVS) diode (SMBJ series)
- Stand-off voltage (VRWM): 28 V
- Peak pulse power: 600 W (10/1000 µs)
- Very fast response time for surge/ESD protection
- Package: SMB (DO-214AB), with tape & reel packaging (-TR)
- Wide operating temperature range (commonly -55°C to +150°C)
- High surge capability with low leakage in normal operation
- RoHS compliant; suitable for automotive/industrial protection applications
- Typical applications: protect DC power rails, communication/data lines, and signal interfaces from transient overvoltage events
Note: Exact clamping voltage and datasheet tolerances vary by lot; refer to the manufacturer’s datasheet for precise numbers.

Package

SMBJ28CA-TR uses the SMBJ (DO-214AA) surface-mount package. The “CA” denotes bidirectional, and “-TR” indicates Tape & Reel packaging.
