Product details
Overview
SM6T10AHE3_B/I from Vishay General Semiconductor is a unidirectional 600 W transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, with 10 V breakdown voltage (VBR = 9.5–10.5 V at 1.0 mA), 14.5 V clamping voltage (VC) at 41 A peak pulse current, and 8.55 V stand-off voltage (VWM). It protects MOSFETs and sensor signal lines in automotive ECUs against inductive switching transients.
For engineers reviewing the SM6T10AHE3_B/I datasheet, SM6T10AHE3_B/I pinout, SM6T10AHE3_B/I application, or SM6T10AHE3_B/I equivalent, key selection criteria include clamping performance under 10/1000 μs surge, AEC-Q101 qualification status, unidirectional polarity marking, and SMB thermal resistance (RθJA = 100 °C/W).
Technical Context
The SM6T10AHE3_B/I uses a glass-passivated silicon junction to achieve low leakage (<10 μA at 8.55 V) and stable breakdown behavior across -65 °C to +150 °C operating range. Its 600 W peak pulse power rating is defined per 10/1000 μs waveform with derating above 25 °C ambient.
Designed for surface-mount automated placement, it features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets MSL level 1 (260 °C peak reflow). The cathode band identifies polarity; no marking on bidirectional variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.50 V / 10.5 V at 1.0 mA - defines precise overvoltage triggering threshold for protection circuit activation |
| VWM | 8.55 V - maximum continuous reverse voltage before significant leakage begins; sets safe operating margin below VBR |
| VC @ IPPM | 14.5 V at 41.0 A - clamping voltage during 600 W transient; determines protected IC's maximum stress exposure |
| PPPM | 600 W - peak pulse power handling capability with 10/1000 μs waveform; quantifies surge energy absorption capacity |
| RθJA | 100 °C/W - junction-to-ambient thermal resistance; governs temperature rise under sustained 5.0 W power dissipation |
| TJ max. | +150 °C - maximum junction temperature; enables operation in under-hood automotive environments |
| AEC-Q101 | Qualified - confirms reliability for automotive electronics per stress test requirements (HTOL, TC, UHAST, etc.) |
Pinout & Package
SMB (DO-214AA) surface-mount package with cathode band marking; 0.205" × 0.220" footprint, 0.077"–0.086" height, matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal (reverse-biased mode) | Connected to protected line; conducts during transient to shunt current to ground |
| Cathode | Current exit terminal (reverse-biased mode) | Marked by band; tied to system ground or lower-potential rail for clamping reference |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables robust protection against ISO 7637-2 Pulse 1/2a/5a transients in 12 V automotive systems |
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity testing, and high-temperature operating life |
| Glass passivated junction | Ensures stable VBR and low leakage over time and temperature; eliminates risk of junction corrosion |
| Low inductance SMB package | Minimizes voltage overshoot during fast-rising transients (e.g., load dump, ESD), improving clamping fidelity |
| MSL Level 1 (260 °C) | Supports standard lead-free reflow without preconditioning; eliminates moisture-related popcorning risk |
Applications
| Automotive Engine Control Unit (ECU) | Industrial Motor Drive Interface |
|---|---|
Use Scenario: Protects microcontroller GPIO and CAN transceiver inputs from inductive kickback during solenoid valve switching. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between signal line and chassis ground to clamp transients below IC absolute maximum ratings. Use Value: Limits clamped voltage to 14.5 V at 41 A, ensuring protected devices remain within 16 V absolute max rating while surviving repeated 600 W surges. |
Use Scenario: Shields RS-485 transceiver data lines from motor drive noise and relay contact bounce in factory automation PLCs. IC Role / Device Role / Timing Role: Standoff-rated TVS (VWM = 8.55 V) placed differential-line-to-ground to suppress common-mode surges without affecting 5 V logic levels. Use Value: Maintains <10 μA leakage at 8.55 V, preventing false triggering or bus contention while delivering 14.5 V clamping during 10/1000 μs events. |
| Consumer Appliance Power Supply | Automotive ADAS Camera Module |

Use Scenario: Safeguards MIPI CSI-2 data lines in rear-view camera modules exposed to load dump and jump-start conditions. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS on high-speed serial interface, mounted adjacent to connector. Use Value: SMB package enables compact layout near connector; 100 °C/W RθJA allows thermal management without heatsink in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | Same VBR (9.5–10.5 V), but 400 W PPPM; SMA package (smaller, higher RθJA = 140 °C/W) | Limited to lower-energy transients; less suitable for automotive load dump where 600 W is required | Select SMAJ10A only if space-constrained and surge energy is confirmed ≤400 W |
| SMCJ10A | Same VBR, 1500 W PPPM; larger SMC (DO-214AB) package with RθJA = 50 °C/W | Over-spec'd for many 12 V systems; requires larger PCB area and may increase cost | Choose SMCJ10A when higher surge margin is needed and board space permits larger footprint |
Compared with SMAJ10A and SMCJ10A, SM6T10AHE3_B/I delivers optimal balance of 600 W surge capability, AEC-Q101 qualification, and SMB footprint-making it the preferred choice for space-limited automotive and industrial designs requiring validated reliability without over-engineering.

FAQ
What is the clamping voltage of SM6T10AHE3_B/I at its rated peak pulse current?
The SM6T10AHE3_B/I has a maximum clamping voltage (VC) of 14.5 V at 41.0 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per Figure 1 in Vishay document 88385 and ensures protected downstream ICs experience minimal overvoltage stress during surge events. The SM6T10AHE3_B/I maintains this clamping performance across its full operating temperature range.
Is SM6T10AHE3_B/I qualified for automotive applications?
Yes, SM6T10AHE3_B/I is AEC-Q101 qualified, as confirmed by its HE3 suffix and explicit statement in Vishay document 88385. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing-making SM6T10AHE3_B/I suitable for under-hood and body-control module applications in passenger vehicles and commercial vehicles.
What does the "HE3_B/I" suffix indicate in SM6T10AHE3_B/I?
The "HE3" denotes RoHS-compliant and AEC-Q101 qualified construction; "B" is the revision code; and "I" specifies packaging in 13-inch tape-and-reel format with 3200 units per reel. This matches Vishay's ordering information table in document 88385, confirming SM6T10AHE3_B/I is the automotive-grade, high-volume production variant of the SM6T10A device.
How does the SMB package of SM6T10AHE3_B/I affect thermal performance?
The SMB (DO-214AA) package of SM6T10AHE3_B/I provides a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. This enables reliable operation at its 5.0 W steady-state power dissipation limit up to +75 °C ambient, and supports full 600 W transient capability without thermal runaway-critical for densely packed automotive PCBs where airflow is limited.
Can SM6T10AHE3_B/I be used in bidirectional configurations?
No, SM6T10AHE3_B/I is strictly unidirectional, as indicated by its "A" suffix and cathode band marking. Bidirectional variants require the "CA" suffix (e.g., SM6T10CA). Using SM6T10AHE3_B/I in bidirectional circuits would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. Always verify polarity alignment in schematic and layout for SM6T10AHE3_B/I.
