Product details
Overview
SM6T10AHE3/5B from Vishay General Semiconductor is a unidirectional surface-mount TRANSZORB® transient voltage suppressor in SMB (DO-214AA) package, with 10 V breakdown voltage (VBR = 9.5–10.5 V at 1.0 mA), 8.55 V stand-off voltage (VWM), 14.5 V clamping voltage (VC) at 41.0 A peak pulse current, and 600 W peak pulse power rating per 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial control systems.
For engineers reviewing the SM6T10AHE3/5B datasheet, SM6T10AHE3/5B pinout, SM6T10AHE3/5B application, or SM6T10AHE3/5B equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, SMB package thermal resistance (RθJA = 100 °C/W), maximum reverse leakage (10.0 μA at VWM), and clamping performance under standardized surge waveforms.
Technical Context
The SM6T10AHE3/5B operates as a unidirectional TVS diode with glass-passivated junction, designed for low-inductance transient suppression on PCB traces carrying sensitive analog or digital signals. Its clamping behavior is defined by a 10/1000 μs waveform test condition, and it meets MSL level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance.
It features a cathode band marking for polarity identification, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and is qualified to AEC-Q101 for automotive applications - distinguishing it from commercial-grade E3/M3 variants by enhanced reliability testing and traceability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.50 V / 10.5 V at 1.0 mA - defines precise breakdown threshold for reliable overvoltage triggering |
| VWM | 8.55 V - maximum continuous reverse operating voltage before leakage exceeds 10 μA |
| VC @ IPPM | 14.5 V at 41.0 A - clamping voltage during 600 W 10/1000 μs surge, limiting stress on downstream ICs |
| PPPM | 600 W - peak pulse power handling capability under standardized transient conditions |
| TJ max. | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same SMB package, 600 W rating, but VBR = 11.1–12.3 V and VC = 16.0 V - higher clamping voltage than SM6T10AHE3/5B | Less effective for 8.55 V systems requiring tight clamping margin; suitable where higher VWM is acceptable | Select SMAJ10A only if design allows ≥16.0 V transient excursion and AEC-Q101 is not required |
| 1.5SMC10A | Higher-power SMC package (1500 W), same VBR range, but larger footprint and RθJA = 15 °C/W - different thermal and layout constraints | Used in high-energy industrial motor drives where 600 W is insufficient; not drop-in due to size and pad layout | Choose 1.5SMC10A when surge energy exceeds 600 W and board space permits larger SMC footprint |
Compared with SMAJ10A and 1.5SMC10A, SM6T10AHE3/5B delivers tighter clamping (14.5 V), AEC-Q101 qualification, and optimized thermal performance for space-constrained automotive modules - making it preferred for next-generation BCM and ADAS sensor interface designs.

FAQ
What is the breakdown voltage tolerance of SM6T10AHE3/5B?
The SM6T10AHE3/5B has a specified breakdown voltage (VBR) range of 9.50 V to 10.5 V at 1.0 mA test current, per Vishay's datasheet revision 09-Jan-2024. This ±5% tolerance ensures predictable turn-on behavior across production lots and temperature ranges, critical for designs relying on precise overvoltage thresholds. The SM6T10AHE3/5B maintains this specification under standard test conditions and is validated per AEC-Q101 stress requirements.
Is SM6T10AHE3/5B suitable for automotive applications?
Yes, SM6T10AHE3/5B is AEC-Q101 qualified and explicitly designated for automotive use via its "HE3" suffix, indicating RoHS-compliant construction with full qualification to automotive reliability standards. It supports operation from −65 °C to +150 °C and withstands reflow up to 260 °C (MSL level 1). The SM6T10AHE3/5B is commonly deployed in body control modules, sensor interfaces, and infotainment power rails where certified transient immunity is required.
What does the "5B" in SM6T10AHE3/5B indicate?
The "5B" suffix in SM6T10AHE3/5B 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 a 7-inch reel with 750 units. Both share identical electrical and reliability specifications; the "5B" format supports high-volume automated assembly lines requiring extended reel life and reduced changeover frequency. SM6T10AHE3/5B is fully compatible with standard SMB pick-and-place equipment.
How does SM6T10AHE3/5B compare to bidirectional TVS diodes like SM6T10CA?
SM6T10AHE3/5B is unidirectional, meaning it conducts only in reverse bias above VBR, with a cathode band marking polarity. In contrast, SM6T10CA is bidirectional and symmetrical, offering clamping in both directions - suited for AC lines or differential buses. The SM6T10AHE3/5B provides lower leakage (10 μA at 8.55 V) and tighter VBR tolerance than its bidirectional counterpart, making it preferable for DC rail protection where polarity is fixed and leakage must be minimized.
What is the maximum clamping voltage of SM6T10AHE3/5B under surge conditions?
The SM6T10AHE3/5B has a maximum clamping voltage (VC) of 14.5 V at 41.0 A peak pulse current, tested with a 10/1000 μs waveform. This value represents the upper limit of voltage seen by protected circuitry during worst-case transient events. The SM6T10AHE3/5B achieves this performance with low dynamic impedance and fast response, ensuring downstream components such as microcontrollers or transceivers remain within safe operating voltage margins.
