Product details
Overview
SMBJ13CHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 13 V standoff voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 21.5 V maximum clamping voltage (VC) at 27.9 A peak pulse current, and 600 W peak pulse power rating with a 10/1000 µs waveform.
For engineers reviewing the SMBJ13CHE3/5B datasheet, SMBJ13CHE3/5B pinout, SMBJ13CHE3/5B application, or SMBJ13CHE3/5B equivalent, this device is selected for robust overvoltage protection on DC power rails, I/O lines, and sensor interfaces in automotive, industrial, and telecom systems where AEC-Q101 qualification, low clamping ratio, and fast response time are critical.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, conducting only when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable leakage performance and long-term reliability under repetitive surge stress.
Designed for surface-mount assembly on standard PCB copper pads (0.2" × 0.2"), it delivers 600 W peak pulse power handling with 0.01% duty cycle, and exhibits a low incremental surge resistance that minimizes voltage overshoot during transient events. Thermal resistance is 100 °C/W (junction-to-ambient) and 20 °C/W (junction-to-lead).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A-E3/5B | No AEC-Q101 qualification; commercial-grade only | Not suitable for automotive production; acceptable for industrial prototypes | Select when AEC-Q101 is not required and cost sensitivity is higher |
| SMBJ13AHM3/5B | Halogen-free, RoHS-compliant, AEC-Q101 qualified | Same automotive qualification but with halogen-free molding compound | Choose for automotive programs requiring halogen-free compliance per JESD201 Class 2 |
Compared with SMBJ13CHE3/5B, SMBJ13A-E3/5B lacks automotive qualification and may require additional validation for vehicle use, while SMBJ13AHM3/5B adds halogen-free compliance without sacrificing electrical performance-making it ideal for Tier 1 automotive supply chains with strict material declarations.

FAQ
What is the clamping voltage of SMBJ13CHE3/5B at its rated peak pulse current?
The SMBJ13CHE3/5B has a maximum clamping voltage (VC) of 21.5 V at its rated peak pulse current of 27.9 A using the standard 10/1000 µs waveform. This value is measured under defined test conditions and ensures downstream components remain within safe operating limits during surge events. The SMBJ13CHE3/5B achieves this with low incremental resistance, contributing to consistent clamping performance across temperature and lifetime.
Is SMBJ13CHE3/5B qualified for automotive applications?
Yes, SMBJ13CHE3/5B is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in the 88392 datasheet. This qualification validates its reliability for automotive use cases including engine control modules, body electronics, and ADAS sensor interfaces. The SMBJ13CHE3/5B undergoes stress testing for temperature cycling, humidity, and surge endurance per AEC-Q101 requirements.
What does the "5B" in SMBJ13CHE3/5B indicate?
The "5B" denotes the packaging configuration: 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel. This format supports high-volume automated SMT placement and is compatible with standard pick-and-place equipment. The "HE3" portion confirms RoHS compliance and AEC-Q101 qualification, while "5B" specifies the physical delivery mode-not electrical or thermal characteristics.
How does SMBJ13CHE3/5B differ from bidirectional variants like SMBJ13CA?
SMBJ13CHE3/5B is unidirectional and conducts only in reverse bias above VBR, with polarity marked by a cathode band. In contrast, SMBJ13CA is bidirectional and symmetrical, suppressing transients in both directions-suitable for AC-coupled or differential signal lines. The SMBJ13CHE3/5B offers tighter VBR tolerance and lower leakage in DC applications, whereas SMBJ13CA provides balanced clamping but higher capacitance and no polarity marking.
What is the thermal resistance of SMBJ13CHE3/5B, and how does it affect layout design?
SMBJ13CHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and junction-to-lead (RθJL) of 20 °C/W. These values assume mounting on minimum recommended 0.2" × 0.2" copper pads per terminal. To maintain TJ ≤ 150 °C under sustained 5.0 W dissipation, designers must provide adequate copper area and avoid excessive ambient temperatures-especially in enclosed automotive or industrial enclosures.
