Product details
Overview
SMBG54AHE3/5B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of sensitive electronics. It features a 54 V stand-off voltage (VWM), 60.0–66.3 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), <1.0 μA reverse leakage at VWM, and clamps to ≤87.1 V at 6.9 A peak surge current - deployed in automotive power line and sensor interface protection.
For engineers reviewing the SMBG54AHE3/5B datasheet, SMBG54AHE3/5B pinout, SMBG54AHE3/5B application, or SMBG54AHE3/5B equivalent, key selection criteria include its AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, fast response time, and compatibility with automated SMT placement on industrial and automotive PCBs.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, leveraging glass-passivated silicon junction technology for stable avalanche behavior under repetitive transients. Its thermal resistance (RθJA = 100 °C/W, RθJL = 20 °C/W) and MSL Level 1 rating support high-reliability reflow soldering in automotive-grade assemblies.
The SMBG54AHE3/5B delivers precise voltage threshold control with tight VBR tolerance (±5% typical), meets UL 497B recognition (QVGQ2), and sustains 100 A non-repetitive forward surge (8.3 ms half-sine) - enabling protection of MOSFET gates, CAN bus interfaces, and microcontroller I/O lines against ISO 7637-2 pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 54 V - maximum continuous reverse operating voltage before clamping initiates |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ54A-E3/5B | Same VWM/VBR/PPPM, but SMB (DO-214AA) package; RθJA = 110 °C/W vs. 100 °C/W | Larger footprint; lower power density; less suitable for ultra-compact automotive modules | Choose SMBJ54A-E3/5B if legacy layout uses SMB pads or higher thermal margin is acceptable |
| 1.5SMC54A-H | Same electrical specs, but larger SMC (DO-214AB) package; 1.5 kW PPPM rating; RθJA = 60 °C/W | Higher surge endurance but incompatible with dense SMT layouts; not AEC-Q101 qualified | Choose 1.5SMC54A-H only for non-automotive industrial applications requiring extended single-pulse robustness |
Compared with SMBJ54A-E3/5B and 1.5SMC54A-H, the SMBG54AHE3/5B offers optimal balance of AEC-Q101 compliance, SMBG footprint efficiency, and thermal performance - making it preferred for next-generation automotive electronics where space, reliability, and reflow compatibility are critical.

FAQ
What is the maximum clamping voltage of SMBG54AHE3/5B at its rated peak pulse current?
The SMBG54AHE3/5B has a maximum clamping voltage (VC) of 87.1 V when subjected to its rated peak pulse current of 6.9 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88456 and defines the upper voltage limit imposed on protected circuits during surge events. The SMBG54AHE3/5B maintains this clamping performance across its specified operating temperature range.
Is SMBG54AHE3/5B suitable for bidirectional transient suppression?
No, SMBG54AHE3/5B is a unidirectional TVS diode, as indicated by its "A" suffix and cathode-band marking. Bidirectional variants use the "CA" suffix (e.g., SMBG54CA). Using SMBG54AHE3/5B for bidirectional protection would leave the reverse-polarity transient path unprotected. For symmetric surge suppression, select SMBG54CAHE3/5B instead - the SMBG54AHE3/5B must be applied with correct polarity alignment to the protected line.
Does SMBG54AHE3/5B meet automotive qualification standards?
Yes, SMBG54AHE3/5B is explicitly AEC-Q101 qualified, as confirmed in the "MECHANICAL DATA" section of Vishay document 88456. The "HE3" suffix denotes RoHS compliance and AEC-Q101 qualification. This certification validates its reliability for automotive applications including engine control, body electronics, and ADAS subsystems under temperature cycling, humidity, and mechanical stress conditions.
What is the thermal resistance from junction to ambient for SMBG54AHE3/5B?
The SMBG54AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pad per terminal. This value is specified in the "THERMAL CHARACTERISTICS" table of Vishay document 88456 and is critical for calculating safe power derating above 25 °C ambient. Its RθJL is 20 °C/W, supporting efficient heat transfer to PCB traces.
What does the "5B" suffix indicate in SMBG54AHE3/5B?
"5B" denotes the packaging configuration: 13-inch diameter plastic tape and reel, with a base quantity of 3200 units per reel. This differs from "52", which indicates 7-inch tape-and-reel (750 units). Both "5B" and "52" are compatible with standard SMT pick-and-place equipment; "5B" is preferred for high-volume production runs to minimize reel changeovers. The "HE3" portion confirms RoHS compliance and AEC-Q101 qualification.
