概述

Description

SMBJ70A-TR is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMBJ (DO-214AB) package. It protects DC power rails and data lines from voltage transients.
Key points:
- VRWM (working reverse voltage): 70 V
- Unidirectional, SMBJ package; TR suffix = tape-and-reel packaging
- Peak pulse power: 1.5 kW (10/1000 µs)
- Junction temp range: -55 °C to +150 °C
- Typical applications: automotive and industrial electronics, telecom power rails, and any line requiring surge protection
Note: VBR, VCL, and exact tolerances are specified in the datasheet and depend on test conditions.

Features

SMBJ70A-TR features (concise):
- Unidirectional TVS diode (A suffix) in SMBJ DO-214AB package
- Stand-off voltage: VRWM = 70 V
- High surge capability: up to about 1,500 W peak pulse power (10/1000 µs)
- Fast transient protection for power and signal lines
- Wide operating temperature: typically -55°C to +150°C
- RoHS compliant; lead-free
- Packaging: Tape & Reel (TR) for automated assembly
- Low leakage at VRWM and robust clamping under surge
- Suitable for protecting DC rails, telecom/power supplies, and data lines from voltage transients
Note: Exact VBR, VCL values and IT/pulse specs are defined in the datasheet and vary with current; refer to the manufacturer’s sheet for precise limits.

Package

SMBJ70A-TR is a TVS diode in SMB (DO-214AA) surface-mount package, supplied on Tape & Reel (TR).

Pinout

- Pin count: 2 pins (two-terminal device in SMB package, DO-214AB)
- Function: Transient Voltage Suppressor (TVS) diode used to protect circuits from voltage transients by clamping surges.

Manufacturer

- Manufacturer: Vishay Intertechnology, Inc.
- What kind of company: A global designer and manufacturer of electronic components, including discrete semiconductors and passive components (resistors, capacitors, diodes, etc.).

Application

SMBJ70A-TR is a unidirectional TVS diode (SMB package) with about 70V stand-off. Applications: transient protection for DC rails/lines up to ~70V; automotive 12/24V systems (load-dump/spikes); industrial equipment and motor drives; DC-DC converters and solar/battery storage inverters; telecom/network power rails; protection for adapters and switching power supplies. Suitable for IEC 61000-4-5 surges and fast transients.
