Product details
Overview
SMBG160-E3/5B from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-215AA (SMBG) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 160 V standoff voltage (VWM), 178–197 V breakdown range (VBR at 1 mA), 600 W peak pulse power (10/1000 µs), clamping voltage of 259 V at 2.3 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG160-E3/5B datasheet, SMBG160-E3/5B pinout, SMBG160-E3/5B application, or SMBG160-E3/5B equivalent, key selection criteria include unidirectional clamping behavior, junction temperature derating above 25 °C, thermal resistance (RθJA = 100 °C/W), RoHS-compliant matte tin plating, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: under normal conditions it presents high impedance (>1 MΩ leakage at VWM), but triggers into low-impedance conduction when transient voltage exceeds VBR, diverting surge current away from protected circuitry. Its glass-passivated junction ensures stable breakdown characteristics and long-term reliability under repetitive transients.
The device is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine), supports operation from −55 °C to +150 °C junction temperature, and meets MSL Level 1 per J-STD-020 with peak reflow temperature up to 260 °C - confirming suitability for standard lead-free reflow processes without moisture sensitivity concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 178 V / 197 V at 1 mA - precise breakdown threshold defining turn-on tolerance |
| VC @ IPPM | 259 V at 2.3 A - clamped voltage during full-rated 600 W transient, limiting stress on downstream ICs |
| PPPM | 600 W - peak pulse power handling with 10/1000 µs waveform, enabling protection against IEC 61000-4-5 Level 4 surges |
| IFSM | 100 A - single half-sine surge rating (8.3 ms), supporting protection against load dump in 12 V automotive systems |
| TJ max | +150 °C - maximum junction temperature, allowing use in under-hood or high-ambient industrial environments |
| RθJA | 100 °C/W - thermal resistance to ambient on standard 5.0 mm × 5.0 mm pads, guiding PCB thermal layout |
Pinout & Package

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 | Same VWM (160 V), identical DO-214AA (SMB) package but slightly higher VC (260 V @ 2.3 A) and lower IPPM rating | Lower peak pulse power (600 W same), but higher RθJA (125 °C/W) limits thermal performance in high-density layouts | Select SMBJ160A-E3/52 only if legacy SMB footprint compatibility is required; SMBG160-E3/5B offers superior thermal dissipation and AEC-Q101 qualification |
| 1.5SMC160A | Same VWM/VBR specs, but DO-214AB (SMC) package - larger footprint (7.11 mm × 6.22 mm) and higher PPPM (1500 W) | Higher surge capacity suits heavy industrial motor drives, but requires PCB redesign due to larger pad layout and height | Choose 1.5SMC160A when >600 W surge margin is mandatory; SMBG160-E3/5B is optimal for space-constrained automotive and telecom modules |
Compared with SMBJ160A-E3/52 and 1.5SMC160A, SMBG160-E3/5B delivers AEC-Q101 validation, lower thermal resistance (100 vs. 125 °C/W), and DO-215AA's optimized gull-wing leadform for fine-pitch automated placement - making it the preferred choice for next-generation automotive ECUs and compact telecom power supplies.

FAQ
What is the clamping voltage of SMBG160-E3/5B and how does it protect downstream circuitry?
The SMBG160-E3/5B clamps at 259 V when subjected to its rated peak pulse current of 2.3 A (10/1000 µs waveform). This defined clamping voltage ensures that any transient exceeding the 160 V standoff level is limited to ≤259 V, protecting sensitive downstream components like regulators and microcontrollers from overvoltage stress. The low incremental surge resistance enables rapid energy diversion without excessive voltage overshoot.
Is SMBG160-E3/5B suitable for automotive applications?
Yes, SMBG160-E3/5B is AEC-Q101 qualified and explicitly rated for automotive use. Its −55 °C to +150 °C operating junction temperature range, 100 A load dump surge capability, and MSL Level 1 reflow compatibility make it appropriate for engine control units, body control modules, and ADAS power supplies where reliability under thermal and electrical stress is critical.
How does the DO-215AA (SMBG) package differ from DO-214AA (SMB)?
The DO-215AA (SMBG) package features a gull-wing leadform with tighter pitch and lower profile than DO-214AA (SMB), enabling finer-pitch automated placement and improved thermal performance (RθJA = 100 °C/W vs. 125 °C/W for SMB). SMBG also uses optimized copper pad layout (5.0 mm × 5.0 mm per terminal) to maximize power dissipation - a key advantage for high-density automotive PCBs.
What is the maximum reverse leakage current for SMBG160-E3/5B at its standoff voltage?
At its 160 V standoff voltage (VWM) and 25 °C ambient temperature, the SMBG160-E3/5B exhibits a maximum reverse leakage current (ID) of 1.0 µA. This ultra-low leakage preserves system efficiency in always-on circuits and prevents false triggering in high-impedance sensing paths, especially important in battery-powered and precision analog applications.
Does SMBG160-E3/5B require external series impedance for effective protection?
No, SMBG160-E3/5B functions as a standalone shunt protector and does not require external series impedance to operate. However, in bidirectional signal line protection, it is typically paired with series resistors or ferrites to manage common-mode transients - while SMBG160-E3/5B itself handles differential-mode overvoltage by clamping between the line and ground reference.
