Product details
Overview
SMBG160HE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for robust overvoltage protection of power rails and signal lines. It features a 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), and clamps transients to ≤259 V at 2.3 A peak pulse current - deployed in automotive power supply inputs and industrial motor drive control circuits.
For engineers reviewing the SMBG160HE3/5B datasheet, SMBG160HE3/5B pinout, SMBG160HE3/5B application, or SMBG160HE3/5B equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (–55 to +150 °C), and RoHS-compliant HE3 suffix marking - all critical for automotive-grade ESD/surge protection design-in.
Technical Context
This unidirectional TVS diode operates as a voltage-clamping device triggered by reverse-biased avalanche breakdown. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1.0 ns), while the low incremental surge resistance enables effective energy diversion during transient events.
The SMBG160HE3/5B is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine), supports automated SMT placement, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak. Its thermal performance is characterized by RθJL = 20 °C/W (junction-to-lead), enabling reliable operation under high-duty-cycle surge conditions when mounted on 5.0 mm × 5.0 mm copper pads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ160A-E3/5B | Same VWM (160 V), identical DO-214AA (SMB) package but slightly higher VC (269 V @ 2.2 A) and lower PPPM (600 W same, but derated faster above 25 °C) | Not AEC-Q101 qualified; suitable for commercial/industrial use only | Select SMBJ160A-E3/5B only if automotive qualification is not required and cost optimization is prioritized. |
| SMCJ160AHE3/5B | Higher PPPM (1500 W), larger DO-214AB (SMC) package, same VWM/VBR range, AEC-Q101 qualified | Used where higher surge immunity (e.g., ISO 7637-2 Pulse 5b) or longer surge duration is mandated | Choose SMCJ160AHE3/5B when system-level testing requires >600 W headroom or PCB layout allows larger footprint. |
Compared with SMBG160HE3/5B, SMBJ160A-E3/5B offers identical standoff voltage but lacks automotive qualification and has tighter thermal derating, while SMCJ160AHE3/5B provides triple the surge power in a larger package - making SMBG160HE3/5B the optimal balance of AEC-Q101 compliance, compact SMBG footprint, and validated 600 W performance for space-constrained automotive modules.

FAQ
What is the clamping voltage of SMBG160HE3/5B at its rated peak pulse current?
The SMBG160HE3/5B clamps to a maximum of 259 V at its specified peak pulse current of 2.3 A (10/1000 µs waveform). This value is measured under standardized test conditions with 5.0 mm × 5.0 mm copper pads per terminal and defines the upper voltage limit imposed on protected circuitry during surge events - a key parameter for ensuring downstream ICs remain within absolute maximum ratings.
Is SMBG160HE3/5B qualified for automotive applications?
Yes, SMBG160HE3/5B is AEC-Q101 qualified, as confirmed by Vishay's documentation and the "HE3" suffix designation. This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT), validating its suitability for under-hood and chassis-mounted automotive electronics such as body control modules and ADAS power supplies.
What does the "HE3" suffix mean in SMBG160HE3/5B?
The "HE3" suffix in SMBG160HE3/5B indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. Unlike the commercial "E3" variant, the "H" denotes automotive-grade screening and enhanced reliability testing, while "E3" specifies lead-free matte tin plating compliant with JEDEC standards - essential for Tier 1 automotive supply chain compliance.
How does SMBG160HE3/5B differ from SMBJ160A-E3/5B?
SMBG160HE3/5B uses the smaller DO-215AA (SMBG) package versus DO-214AA (SMB) for SMBJ160A-E3/5B, shares identical VWM (160 V) and PPPM (600 W), but differs critically in qualification: SMBG160HE3/5B is AEC-Q101 qualified and rated for 150 °C max junction temperature, whereas SMBJ160A-E3/5B is commercial-grade only and lacks automotive validation.
What is the maximum reverse leakage current for SMBG160HE3/5B at rated standoff voltage?
The SMBG160HE3/5B exhibits a maximum reverse leakage current (ID) of 1.0 µA at its rated stand-off voltage (VWM) of 160 V and ambient temperature of 25 °C. This low leakage ensures minimal power loss in always-on automotive modules and preserves battery life in infotainment and telematics systems powered directly from vehicle batteries.
