Product details
Overview
SMBJ160AHE3_B/H 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 160 V stand-off voltage (VWM), 178–197 V breakdown voltage (VBR) at 1 mA, 2.3 A peak pulse current (IPPM) under 10/1000 µs waveform, and clamps to ≤259 V at rated surge current - used for safeguarding MOSFETs, ICs, and sensor signal lines in industrial and telecom equipment.
For engineers reviewing the SMBJ160AHE3_B/H datasheet, SMBJ160AHE3_B/H pinout, SMBJ160AHE3_B/H application, or SMBJ160AHE3_B/H equivalent, key selection criteria include its AEC-Q101 qualification status, 600 W peak pulse power rating, low incremental surge resistance, and compatibility with automated SMT placement on PCBs requiring robust overvoltage protection without derating at elevated ambient temperatures.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-banded polarity, leveraging a glass-passivated silicon junction for stable avalanche behavior and fast response (<1 ns). Its thermal resistance (RθJA = 100 °C/W) and maximum junction temperature of 150 °C enable reliable operation in compact layouts with minimal copper pad area (0.2" × 0.2").
The SMBJ160AHE3_B/H meets J-STD-020 MSL Level 1 moisture sensitivity and supports lead-free reflow up to 260 °C peak. Its 1.0 µA max reverse leakage at VWM ensures minimal standby power loss in high-impedance circuits such as sensor bias networks or microcontroller I/O protection paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 160 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 178–197 V at IT = 1 mA - Confirmed avalanche onset range; ensures predictable clamping initiation during transients. |
| VC (Clamping Voltage) | ≤259 V at IPPM - Peak voltage seen by protected circuit during 10/1000 µs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 600 W - Surge energy handling capability per single 10/1000 µs event; enables protection against IEC 61000-4-5 Level 4 surges. |
| IPPM (Peak Pulse Current) | 2.3 A - Maximum non-repetitive surge current supported; sets minimum trace width and fuse coordination requirements. |
| TJ max. | 150 °C - Maximum allowable junction temperature; constrains thermal design in enclosed or high-ambient environments. |
| Package | SMB (DO-214AA) - Standardized surface-mount outline with 5.59 mm × 4.06 mm footprint; compatible with JEDEC-compliant pick-and-place equipment. |
Pinout & Package
Package: SMB (DO-214AA), molded plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102; polarity indicated by cathode band on one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference terminal | Connected to ground or lowest potential node; completes clamping path when transient exceeds VBR. |
| Cathode | High-side transient input terminal | Connected to protected line (e.g., power rail or signal); band-marked end accepts positive surge relative to anode. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for under-hood and ADAS subsystems. |
| 600 W peak pulse power | Supports IEC 61000-4-5 surge immunity up to 4 kV (line-earth) without degradation across 1000+ events at 0.01% duty cycle. |
| Low profile SMB package | Height ≤2.20 mm enables use in space-constrained modules like IoT edge nodes and modular power supplies where Z-height is critical. |
| Glass passivated junction | Ensures stable VBR tolerance and long-term parameter stability under thermal cycling and humidity exposure per JESD22-A101. |
| MSL Level 1 rating | Allows unlimited floor life and standard reflow without baking - reduces manufacturing overhead in high-volume SMT lines. |

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-E3/52 | Commercial-grade RoHS-compliant version without AEC-Q101 qualification; identical electrical specs and SMB package. | Lacks automotive qualification; suitable for industrial/commercial designs not requiring automotive reliability validation. | Select SMBJ160AHE3_B/H when AEC-Q101 compliance is mandatory; choose SMBJ160A-E3/52 for cost-sensitive non-automotive applications. |
| SMCJ160AHE3_A/H | Same VWM/VBR/VC ratings but in larger SMC (DO-214AB) package with higher PPPM (1500 W) and IPPM (10.3 A). | Requires larger PCB footprint and higher thermal mass; better suited for higher-energy surge environments like AC mains input stages. | Choose SMBJ160AHE3_B/H for space-constrained 600 W protection; select SMCJ160AHE3_A/H only if >600 W surge margin is required and layout allows SMC footprint. |
Compared with SMBJ160A-E3/52, the SMBJ160AHE3_B/H adds AEC-Q101 qualification without altering clamping performance, making it ideal for automotive ECUs; versus SMCJ160AHE3_A/H, it trades 2.5× lower surge capacity for 40% smaller board area and compatibility with fine-pitch SMT processes.

FAQ
What is the clamping voltage of SMBJ160AHE3_B/H at its rated peak pulse current?
The SMBJ160AHE3_B/H has a maximum clamping voltage (VC) of 259 V when subjected to its rated peak pulse current (IPPM) of 2.3 A under the standard 10/1000 µs waveform. This value is measured at the device terminals and represents the upper voltage limit imposed on the protected circuit during surge events, ensuring downstream components remain within safe operating limits.
Is SMBJ160AHE3_B/H suitable for automotive applications?
Yes, SMBJ160AHE3_B/H is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, highly accelerated life testing (HALT), and ESD verification per automotive standards. This makes SMBJ160AHE3_B/H appropriate for use in body control modules, infotainment systems, and other non-safety-critical automotive electronics where transient immunity and long-term reliability are required.
What does the "HE3" suffix indicate in SMBJ160AHE3_B/H?
The "HE3" suffix in SMBJ160AHE3_B/H denotes a RoHS-compliant, AEC-Q101 qualified variant with matte tin-plated leads and JESD201 Class 2 whisker resistance. The "B/H" portion specifies packaging: 7-inch tape-and-reel format with 750 units per reel, using Vishay's preferred H carrier tape configuration for automated assembly.
How does SMBJ160AHE3_B/H compare to bidirectional TVS diodes like SMBJ160CA?
SMBJ160AHE3_B/H is unidirectional and intended for DC circuits where polarity is fixed - it conducts only during reverse-biased surges. In contrast, SMBJ160CA is bidirectional and symmetric, suitable for AC lines or differential signals. Using SMBJ160AHE3_B/H in place of SMBJ160CA would leave positive-going transients unprotected unless additional circuitry is added, so selection must match system polarity requirements.
What is the thermal resistance and maximum power dissipation of SMBJ160AHE3_B/H?
The SMBJ160AHE3_B/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W and a steady-state power dissipation (PD) rating of 5.0 W at TA = 50 °C on an infinite heatsink. These values define its ability to dissipate heat during sustained overvoltage conditions and inform PCB copper area requirements - for example, mounting on 0.2" × 0.2" pads achieves the published RθJA.
