Product details
Overview
SMBJ16CHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in the SMB (DO-214AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 16 V stand-off voltage (VWM), 26.0 V maximum clamping voltage (VC) at 23.1 A peak pulse current (IPPM), and 600 W peak pulse power capability with a 10/1000 µs waveform - deployed on power rails and signal lines in industrial motor drives.
For engineers reviewing the SMBJ16CHE3/5B datasheet, SMBJ16CHE3/5B pinout, SMBJ16CHE3/5B application, or SMBJ16CHE3/5B equivalent, this device is selected for high-reliability surge suppression where AEC-Q101 qualification, low clamping ratio, and MSL Level 1 moisture sensitivity are critical design requirements.
Technical Context
The SMBJ16CHE3/5B operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its 17.8–19.7 V breakdown range (VBR at 1 mA). Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1.0 ns), enabling effective suppression of ESD and lightning-induced transients.
Thermally, it supports operation from –55 °C to +150 °C with a junction-to-ambient thermal resistance (RθJA) of 100 °C/W on standard 0.2" × 0.2" copper pads. The matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance standards.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ16A-E3/5B | Commercial-grade (non-AEC-Q101), identical electrical specs and SMB package | Lacks automotive qualification; unsuitable for under-hood or safety-critical modules | Select when cost-sensitive industrial designs do not require automotive reliability validation |
| SMBJ16CAHE3/5B | Bidirectional variant with same VWM (16 V), symmetric clamping in both polarities | Used where AC-coupled or bidirectional signal lines (e.g., RS-485, CAN) require symmetrical protection | Choose only if circuit topology demands clamping for both positive and negative transients |
Compared with SMBJ16A-E3/5B and SMBJ16CAHE3/5B, the SMBJ16CHE3/5B uniquely combines AEC-Q101 qualification with unidirectional clamping - making it the preferred choice for automotive power distribution nodes where reliability and polarity-specific suppression are jointly required.

FAQ
What is the clamping voltage of SMBJ16CHE3/5B at its rated peak pulse current?
The SMBJ16CHE3/5B has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current of 23.1 A under a 10/1000 µs waveform. This value is measured per IEC 61000-4-5 and defines the upper voltage limit imposed on protected circuitry during surge events. The SMBJ16CHE3/5B maintains this clamping performance across its full operating temperature range.
Is SMBJ16CHE3/5B suitable for automotive applications?
Yes, SMBJ16CHE3/5B is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD verification per JESD22 standards. Its RoHS-compliant construction, MSL Level 1 rating, and guaranteed performance from –55 °C to +150 °C make SMBJ16CHE3/5B appropriate for under-hood and body electronics where reliability is mandatory.
How does the SMBJ16CHE3/5B differ from the SMBJ16A-E3/5B?
The SMBJ16CHE3/5B and SMBJ16A-E3/5B share identical electrical parameters and SMB (DO-214AA) packaging, but SMBJ16CHE3/5B carries AEC-Q101 qualification and is designated for automotive-grade use. The "HE3" suffix explicitly indicates this qualification, whereas "E3" denotes commercial-grade only. Both parts have the same 16 V stand-off and 26.0 V clamping, but only SMBJ16CHE3/5B is approved for automotive safety-critical functions.
What is the maximum reverse leakage current of SMBJ16CHE3/5B at its stand-off voltage?
The SMBJ16CHE3/5B exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 16 V stand-off voltage (VWM) and 25 °C ambient temperature. This low leakage ensures minimal power loss in always-on systems and prevents unintended biasing of downstream circuitry - a key requirement in battery-powered and low-quiescent-current applications using SMBJ16CHE3/5B.
Can SMBJ16CHE3/5B be used in bidirectional signal protection?
No, SMBJ16CHE3/5B is a unidirectional TVS diode, intended for protection of DC rails or single-polarity signal paths. For bidirectional applications such as RS-485, CAN, or AC-coupled interfaces, the bidirectional variant SMBJ16CAHE3/5B must be used instead. Attempting to use SMBJ16CHE3/5B in bidirectional configurations risks forward conduction and failure during negative transients.
