Overview

Description

5.0SMDJ45CA is a high‑power TVS (transient voltage suppressor) diode in the SMDJ package, used to protect circuits from voltage surges on 5 V rails and data lines (ESD, inductive spikes, load dumps). The “5.0” denotes a nominal stand‑off voltage around 5 V. The “CA” suffix typically indicates a bidirectional automotive‑rated device in this family, and “45” is the series code within the part. It provides fast response and very high peak pulse power (short‑duration surges), making it suitable for USB, microcontroller supplies, and other 5 V systems in automotive/industrial environments. For exact ratings (standing voltage, breakdown, clamping, peak pulse current, temp range) refer to the manufacturer’s datasheet.

Equivalent

5.0SMDJ45CA is a 1500W TVS diode (SMDJ package) with about 45 V standoff (CA suffix = bidirectional). Cross-references from other vendors include:
- Bourns CDSODJ45CA
- ProTek PTVS45CA
- STMicroelectronics SMBJ45CA/SMCJ45CA (same rating; verify package)
Note: exact footprint and bidirectional/unidirectional variant must match; verify in datasheets.

Pinout

- Pin count: 2 pins (two-terminal device)
- Function: Surface-mount transient-voltage-suppressor (TVS) diode used to clamp voltage transients/ESD and protect circuits on the protected line.

Manufacturer

Manufacturer: Littelfuse, Inc.
What kind of company: A global electronics components company specializing in circuit protection devices (fuses, TVS diodes, varistors, gas discharge tubes, etc.) and safety components.

Application

5.0SMDJ45CA is a high-power TVS diode (transient voltage suppressor) designed for surge protection on lines up to about 45 V. Common application areas include:
- Automotive, 12/24/48 V systems
- Industrial and telecom DC rails (protection for 48 V/other high-voltage rails)
- Power-supply and DC-DC converter input protection
- Solar/battery management and energy-storage systems
- Protection of data/communication lines (USB, Ethernet, HDMI) and other sensitive electronics
- Motor drives, inverters, and other industrial automation equipment against surges and ESD.

Package

DO-214AB (SMC) surface-mount package.
