Product details
Overview
SMBG110AHE3/5B 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 110 V stand-off voltage (VWM), 122–135 V breakdown voltage (VBR) at 1 mA, 177 V maximum clamping voltage (VC) at 3.4 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect automotive sensor signal lines, industrial I/O ports, and DC power rails against ESD and inductive switching transients.
For engineers reviewing the SMBG110AHE3/5B datasheet, SMBG110AHE3/5B pinout, SMBG110AHE3/5B application, or SMBG110AHE3/5B equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), junction temperature range (−55 °C to +150 °C), and packaging configuration for rapid design-in and reliability validation.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging an avalanche breakdown mechanism to limit transient voltages above its VWM threshold. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at 110 V) and fast response time (<1 ns), critical for protecting MOSFET gates and microcontroller I/O pins.
The SMBG110AHE3/5B is rated for 100 A non-repetitive forward surge current (IFSM, 8.3 ms half-sine), supports automated SMT placement, and meets J-STD-020 MSL Level 1 with 260 °C reflow peak - confirming suitability for high-volume automotive and industrial PCB assembly without moisture sensitivity concerns.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A-E3/5B | Same VWM (110 V), but lower PPPM (600 W same), higher VC (187 V vs. 177 V), not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use where AEC compliance is not required | Select SMBG110AHE3/5B when automotive-grade reliability and extended temperature operation are mandatory |
| SMCJ110AHE3/5B | Same VWM/VBR, but larger SMC (DO-214AB) package, higher PPPM (1500 W), RθJA = 35 °C/W | Higher power handling and better thermal dissipation, but requires larger PCB area and different pad layout | Choose SMBG110AHE3/5B for space-constrained designs needing AEC-Q101 and SMB footprint compatibility |
Compared with SMBJ110A-E3/5B and SMCJ110AHE3/5B, SMBG110AHE3/5B uniquely balances AEC-Q101 qualification, compact SMBG footprint, and optimized clamping performance (177 V) - making it ideal for automotive body electronics and space-limited industrial modules requiring certified surge resilience.

FAQ
What is the clamping voltage of SMBG110AHE3/5B at its rated peak pulse current?
The SMBG110AHE3/5B has a maximum clamping voltage (VC) of 177 V at its specified peak pulse current (IPPM) of 3.4 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components see limited overvoltage during surge events. The SMBG110AHE3/5B maintains this clamping performance across its full operating temperature range.
Is SMBG110AHE3/5B qualified for automotive applications?
Yes, SMBG110AHE3/5B is AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number: 88456, Revision: 09-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature reverse bias, and ESD, validating its suitability for under-hood and chassis-mounted automotive electronics. The "HE3" suffix explicitly denotes AEC-Q101 qualification.
What does the "5B" suffix indicate in SMBG110AHE3/5B?
"5B" indicates the preferred package code for 13-inch diameter plastic tape and reel delivery, containing 3200 units per reel. This format supports high-speed automated pick-and-place assembly. The "HE3" portion confirms RoHS compliance and AEC-Q101 qualification, while "5B" specifies the packaging configuration - distinct from "52", which denotes 7-inch reels with 750 units.
Can SMBG110AHE3/5B be used in bidirectional configurations?
No, SMBG110AHE3/5B is a unidirectional TVS diode, as indicated by the "A" (not "CA") suffix and absence of bidirectional marking in its electrical table. Bidirectional variants use the "CA" suffix (e.g., SMBG110CA). Using SMBG110AHE3/5B in bidirectional circuits would result in forward conduction during negative transients, potentially causing failure. Always verify polarity marking (cathode band) during layout.
What is the thermal resistance of SMBG110AHE3/5B, and how does it affect PCB layout?
SMBG110AHE3/5B has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain safe junction temperatures under repeated surges, designers must adhere to this pad layout - reducing copper area increases RθJA, risking thermal runaway. No additional heatsinking is required for single-event transients, but layout must match the datasheet's recommended footprint.
