Product details
Overview
SM6T10AHE3_B/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 10 V breakdown voltage (VBR = 9.5–10.5 V at IT = 1.0 mA), 14.5 V clamping voltage (VC) at 41.0 A peak pulse current, and 600 W peak pulse power with 10/1000 μs waveform. It provides robust ESD and surge protection for automotive sensor signal lines and MOSFET gate drivers.
For engineers reviewing the SM6T10AHE3_B/H datasheet, SM6T10AHE3_B/H pinout, SM6T10AHE3_B/H application, or SM6T10AHE3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 8.55 V stand-off voltage (VWM), 10 μA max reverse leakage at VWM, and thermal resistance of 100 °C/W (junction-to-ambient).
Technical Context
The SM6T10AHE3_B/H operates as a clamping-type TVS diode with glass-passivated junction and low-inductance SMB package optimized for fast transient response. Its breakdown behavior follows standard avalanche characteristics with tight VBR tolerance (±5% typical) and defined clamping performance under standardized 10/1000 μs surge conditions.
Designed for surface-mount automated assembly, it meets J-STD-020 MSL Level 1 and JESD 201 Class 2 whisker resistance. The cathode band marking indicates polarity, and its AEC-Q101 qualification confirms suitability for automotive-grade reliability requirements including temperature cycling and humidity testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.50 V / 10.5 V at 1.0 mA - defines precise avalanche onset threshold for accurate 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 - clamped voltage during 600 W surge, limiting stress on downstream ICs |
| PPPM | 600 W - peak pulse power handling with 10/1000 μs waveform per industry standard |
| RθJA | 100 °C/W - thermal resistance determines derating above 25 °C ambient for sustained reliability |
| 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 VBR range (9.5–10.5 V), but 400 W PPPM and SMA package (higher RθJA = 140 °C/W) | Limited to lower-energy transients; less suitable for automotive load-dump where 600 W is required | Select SM6T10AHE3_B/H when AEC-Q101 qualification and higher surge margin are mandatory |
| SMCJ10A | Same VBR, 1500 W PPPM, larger SMC (DO-214AB) package, higher capacitance (~100 pF vs. ~50 pF) | Better for high-energy surges but may degrade signal integrity on high-speed lines due to higher junction capacitance | Choose SM6T10AHE3_B/H for space-constrained PCBs needing automotive-grade reliability without excessive capacitance |
Compared with SMAJ10A and SMCJ10A, SM6T10AHE3_B/H delivers optimal balance of AEC-Q101 compliance, 600 W surge capability, SMB footprint, and low clamping voltage-making it preferred for compact, high-reliability automotive and industrial signal-line protection where layout area and thermal management are constrained.

FAQ
What is the breakdown voltage tolerance for SM6T10AHE3_B/H?
The SM6T10AHE3_B/H has a specified breakdown voltage range of 9.50 V to 10.5 V at test current IT = 1.0 mA, corresponding to ±5% tolerance around the nominal 10 V rating. This tight VBR window ensures consistent clamping behavior across production lots and supports precise overvoltage threshold design in safety-critical circuits such as automotive ECUs where SM6T10AHE3_B/H is deployed.
Is SM6T10AHE3_B/H suitable for bidirectional transient protection?
No, SM6T10AHE3_B/H is a unidirectional TVS diode, as confirmed by its part number suffix "A" and explicit designation in Vishay's SM6T datasheet Table 1. Bidirectional variants use the "CA" suffix (e.g., SM6T10CA). Using SM6T10AHE3_B/H in bidirectional applications would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit-always verify polarity alignment when placing SM6T10AHE3_B/H in designs.
What does the "HE3" suffix indicate in SM6T10AHE3_B/H?
The "HE3" suffix in SM6T10AHE3_B/H denotes RoHS-compliant construction with AEC-Q101 qualification, distinguishing it from commercial-grade "E3" parts. The "H" in the ordering code specifies the 7" tape-and-reel packaging format (750 units per reel), while "B/H" indicates revision level and packaging variant per Vishay's ordering nomenclature. This makes SM6T10AHE3_B/H appropriate for automotive production where both regulatory compliance and reliability certification are mandatory.
What is the maximum clamping voltage of SM6T10AHE3_B/H under surge conditions?
The SM6T10AHE3_B/H has a maximum clamping voltage VC of 14.5 V at peak pulse current IPPM = 41.0 A, measured with a 10/1000 μs waveform. This value is guaranteed across temperature and lifetime, and it defines the upper voltage limit imposed on protected circuitry during surge events-critical for ensuring that downstream components like 5 V microcontrollers or 12 V analog front-ends remain within their absolute maximum ratings when SM6T10AHE3_B/H is active.
How does the SMB package of SM6T10AHE3_B/H affect thermal performance?
The SMB (DO-214AA) package of SM6T10AHE3_B/H provides a typical junction-to-ambient thermal resistance RθJA of 100 °C/W under standard JEDEC test conditions (0.2" × 0.2" copper pads). This allows SM6T10AHE3_B/H to dissipate 5.0 W continuously at TA = 50 °C, but requires careful PCB layout-such as increased copper area or thermal vias-for sustained high-power surge duty cycles. Its low-profile form factor also enables dense placement near vulnerable nodes without compromising board height.
