Product details
Overview
SM15T10AHE3_A/H from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in SMC (DO-214AB) package, with 10 V standoff voltage (VWM = 8.55 V), 14.5 V clamping voltage at 103 A peak pulse current (10/1000 μs), and AEC-Q101 qualification for automotive use. It protects MOSFETs, ICs, and sensor signal lines against lightning-induced and inductive-switching transients.
For engineers reviewing the SM15T10AHE3_A/H datasheet, SM15T10AHE3_A/H pinout, SM15T10AHE3_A/H application, or SM15T10AHE3_A/H equivalent, key selection criteria include unidirectional polarity, 1500 W peak pulse power rating, 14.5 V clamping performance at 103 A, AEC-Q101 qualification status, and SMC package thermal resistance (RθJA = 75 °C/W).
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with sensitive downstream circuitry, activating when reverse voltage exceeds its breakdown threshold (VBR min = 9.50 V). Its low-inductance SMC package and glass-passivated junction enable fast response to 10/1000 μs transients while maintaining stable clamping under high surge conditions.
The device exhibits a maximum reverse leakage of 10 μA at 8.55 V standoff and fails short-circuit under overstress - a predictable, system-safe failure mode. Thermal design must account for RθJL = 15 °C/W junction-to-lead resistance and derating above 25 °C ambient per Figure 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 8.55 V - Maximum continuous reverse voltage before conduction begins; defines operating margin below clamping threshold |
| VBR (Breakdown Voltage) | 9.50–10.5 V at 1.0 mA - Confirmed avalanche initiation range; ensures reliable turn-on during overvoltage events |
| VC (Clamping Voltage) | 14.5 V at IPPM = 103 A (10/1000 μs) - Actual voltage seen by protected circuit during worst-case surge; critical for IC survivability |
| PPPM (Peak Pulse Power) | 1500 W - Sustained energy absorption capability for lightning and switching transients without degradation |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards |
| RθJA | 75 °C/W - Thermal resistance to ambient on standard 8 mm × 8 mm copper pads; determines power derating in PCB layout |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by band marking; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Reverse-biased terminal for unidirectional clamping | Connects to protected line; conducts when line voltage exceeds VBR relative to anode reference |
| Anode (unmarked end) | Reference/ground return path | Typically tied to system ground or low-impedance return; completes clamping current path during transient |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Enables robust protection against IEC 61000-4-5 Level 4 surges (4 kV/2 Ω) without derating in typical PCB layouts |
| Glass passivated chip junction | Ensures stable VBR and low leakage over lifetime; eliminates risk of moisture-induced parameter drift in humid environments |
| Low inductance SMC package | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), improving clamping fidelity |
| MSL Level 1 (260 °C peak reflow) | Supports single-pass lead-free reflow assembly without popcorn cracking or delamination |
| AEC-Q101 qualified (HE3 suffix) | Validates suitability for automotive powertrain, body control, and ADAS modules requiring zero-defect reliability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A-E3/57T | Lower PPPM (400 W), same VWM (8.55 V), SMA package (higher RθJA = 110 °C/W) | Not AEC-Q101 qualified; suitable only for commercial-grade consumer or industrial non-automotive use | Select when cost sensitivity outweighs automotive qualification and surge energy requirements are ≤400 W |
| 1.5KE10A | Through-hole DO-201 package, identical VWM/VC specs but higher mounting inductance and no AEC-Q101 validation | Limited to legacy designs with through-hole assembly; not suitable for automated SMT production or high-reliability automotive programs | Choose only for repair or backward-compatible replacements where board real estate and reflow compatibility are not constraints |
Compared with SMAJ10A-E3/57T and 1.5KE10A, SM15T10AHE3_A/H delivers 3.75× higher surge power handling, automotive-grade reliability, and optimized SMT manufacturability - making it the sole choice for new AEC-Q101-compliant designs requiring ≥103 A transient current capability.

FAQ
What is the clamping voltage of SM15T10AHE3_A/H at its rated peak pulse current?
The SM15T10AHE3_A/H has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current (IPPM) of 103 A using the standardized 10/1000 μs waveform. This value is measured under defined test conditions per Figure 1 and Table on page 2 of Vishay document 88380, and directly determines the maximum overvoltage stress imposed on downstream circuitry during surge events.
Is SM15T10AHE3_A/H suitable for automotive applications?
Yes, SM15T10AHE3_A/H is AEC-Q101 qualified, as confirmed by its HE3 suffix and explicit listing in Vishay's automotive-grade ordering codes. It meets all stress tests required for automotive use, including temperature cycling, high-temperature reverse bias, and mechanical shock, making it appropriate for body control modules, sensor interfaces, and infotainment power rails.
What does the "_A/H" suffix in SM15T10AHE3_A/H indicate?
The "_A/H" suffix in SM15T10AHE3_A/H specifies packaging configuration: "H" denotes 7-inch diameter plastic tape and reel with 850 units per reel, while "A" indicates the revision level of the packaging specification. This matches Vishay's documented ordering format in section "ORDERING INFORMATION" on page 3 of document 88380.
How does the SMC package of SM15T10AHE3_A/H affect thermal performance?
The SMC (DO-214AB) package of SM15T10AHE3_A/H provides a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads, significantly lower than SMA (110 °C/W) or DO-201 (150 °C/W) alternatives. This enables higher sustained power dissipation and improved reliability in thermally constrained automotive and industrial PCB layouts.
What is the maximum reverse leakage current for SM15T10AHE3_A/H at its standoff voltage?
The SM15T10AHE3_A/H exhibits a maximum reverse leakage current (ID) of 10 μA at its specified standoff voltage (VWM) of 8.55 V, measured at 25 °C ambient per Table on page 2 of Vishay document 88380. This low leakage ensures minimal standby power loss and avoids false triggering in high-impedance sensing circuits.
