Product details
Overview
SMBG150AHE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of DC power rails and signal lines. It features a 150 V stand-off voltage (VWM), 167–185 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), clamping voltage of 243 V at 2.5 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMBG150AHE3/5B datasheet, SMBG150AHE3/5B pinout, SMBG150AHE3/5B application, or SMBG150AHE3/5B equivalent, key selection criteria include clamping performance under 10/1000 µs surge, junction temperature derating above 25 °C, unidirectional polarity marking, 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 bias it presents high impedance (<1.0 µA leakage at 150 V), but triggers avalanche conduction when transient voltage exceeds VBR, diverting surge current away from downstream circuitry. Its glass-passivated junction ensures stable breakdown and low incremental surge resistance.
Thermal design relies on RθJA = 100 °C/W (on 5.0 mm × 5.0 mm pads) and RθJL = 20 °C/W, enabling operation up to TJ = +150 °C. The device meets J-STD-020 MSL Level 1 (260 °C peak reflow) and supports repetitive surges at 0.01% duty cycle.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 150 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 167 V / 185 V at 1 mA - defines reliable turn-on threshold across production lot |
| VC @ IPPM | 243 V at 2.5 A - clamped voltage during full 600 W surge, limiting stress on protected ICs |
| PPPM | 600 W - peak pulse power handling per 10/1000 µs waveform, validated at TA = 25 °C |
| IFSM | 100 A - non-repetitive forward surge rating (8.3 ms half-sine), critical for input rectifier protection |
| TJ max | +150 °C - maximum junction temperature, enabling use in under-hood automotive environments |
| Qualification | AEC-Q101 qualified - certified for automotive electronic systems requiring high reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ150A-E3/5B | Same VWM/VBR/VC, but SMB (DO-214AA) package; RθJA = 110 °C/W vs. 100 °C/W | Slightly lower power density; less suitable for high-ambient automotive under-hood locations | Choose SMBJ150A-E3/5B if legacy PCB uses SMB footprint and thermal margin ≥10 °C exists. |
| SMCJ150A-E3/5B | Same electrical specs, but larger SMC (DO-214AB) package; higher IPPM (32.3 A vs. 2.5 A) and PPPM (1500 W) | Overqualified for 600 W needs; occupies 2.5× board area; better for >1 kV surge immunity | Choose SMCJ150A-E3/5B only when system-level testing requires >1000 W surge headroom or higher IFSM. |
Compared with SMBJ150A-E3/5B and SMCJ150A-E3/5B, SMBG150AHE3/5B delivers optimal balance of 600 W capability, AEC-Q101 compliance, and compact SMBG footprint-enabling higher board density in space-constrained automotive modules without sacrificing thermal performance.

FAQ
What is the clamping voltage of SMBG150AHE3/5B at its rated peak pulse current?
The SMBG150AHE3/5B has a maximum clamping voltage (VC) of 243 V when subjected to its peak pulse current (IPPM) of 2.5 A under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C on recommended 5.0 mm × 5.0 mm copper pads and defines the upper voltage limit imposed on protected circuitry during surge events.
Is SMBG150AHE3/5B suitable for automotive applications?
Yes, SMBG150AHE3/5B is AEC-Q101 qualified and explicitly rated for automotive use. Its construction-including glass-passivated junction, MSL Level 1 reflow compatibility, and operation up to +150 °C junction temperature-meets requirements for engine control units, body electronics, and ADAS modules per ISO 16750-2 and ISO 7637-2 standards.
What does the "HE3" suffix indicate in SMBG150AHE3/5B?
The "HE3" suffix in SMBG150AHE3/5B denotes RoHS-compliant construction with AEC-Q101 qualification. "H" signifies AEC-Q101 qualification, "E3" indicates matte tin plating and industrial-grade RoHS compliance, distinguishing it from non-automotive variants like "E3" or "M3" alone.
How does SMBG150AHE3/5B differ from SMBG150CA?
SMBG150AHE3/5B is unidirectional with cathode marking, while SMBG150CA is bidirectional (no polarity marking) and intended for AC-line or differential-signal protection. Their VBR, VC, and PPPM are identical, but SMBG150AHE3/5B must be oriented correctly in-circuit, whereas SMBG150CA protects both polarities symmetrically.
What is the maximum reverse leakage current for SMBG150AHE3/5B at rated VWM?
At its rated stand-off voltage of 150 V and TA = 25 °C, the SMBG150AHE3/5B exhibits a maximum reverse leakage current (ID) of 1.0 µA. This low leakage ensures minimal power loss in always-on automotive circuits and avoids false triggering in high-impedance sensor bias networks.
