Product details
Overview
SM15T10AHE3_A/I from Vishay General Semiconductor is a unidirectional 1500 W transient voltage suppressor (TVS) in SMC (DO-214AB) package, with 10 V standoff voltage (VWM), 14.5 V clamping voltage (VC) at 103 A peak pulse current, and AEC-Q101 qualification for automotive electronics protection against inductive switching transients and ESD.
For engineers reviewing the SM15T10AHE3_A/I datasheet, SM15T10AHE3_A/I pinout, SM15T10AHE3_A/I application, or SM15T10AHE3_A/I equivalent, this part delivers verified bidirectional-capable surge immunity in high-reliability automotive and industrial power rail and signal line protection designs requiring MSL Level 1, RoHS-compliant, and halogen-free construction.
Technical Context
The SM15T10AHE3_A/I operates as a unidirectional avalanche diode with glass-passivated junction, designed to clamp transient overvoltages above 10 V standoff while maintaining low leakage (<10 μA at VWM) and low clamping impedance. Its 10/1000 μs waveform response enables robust handling of lightning-induced surges and motor-switching spikes.
Thermal design relies on RθJA = 75 °C/W and RθJL = 15 °C/W, with maximum junction temperature of +150 °C and derating above TA = 25 °C per Figure 2. The device fails short-circuit under overstress, consistent with IEC 61000-4-5 compliance expectations for TVS components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 10 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (Breakdown Voltage) | 9.5–10.5 V at 1.0 mA - Confirmed avalanche initiation threshold for reliable turn-on timing |
| VC (Clamping Voltage) | 14.5 V at IPPM = 103 A (10/1000 μs) - Limits downstream IC stress during worst-case surge events |
| PPPM (Peak Pulse Power) | 1500 W - Sustains 10/1000 μs transients typical of IEC 61000-4-5 Level 4 testing |
| TJ max | +150 °C - Enables operation in under-hood automotive environments without thermal shutdown |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |

The SM15T10AHE3_A/I has a maximum clamping voltage (VC) of 14.5 V when subjected to its rated peak pulse current (IPPM) of 103 A under the standard 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88380 and ensures downstream components remain within safe operating voltage limits during surge events.
Is SM15T10AHE3_A/I suitable for automotive applications?
Yes, SM15T10AHE3_A/I is AEC-Q101 qualified, as confirmed by its HE3 suffix and explicit listing in Vishay's automotive-grade ordering table. It meets requirements for temperature cycling, high-temperature reverse bias, and ESD robustness required in engine control units, body electronics, and ADAS modules.
What does the "_A/I" suffix mean in SM15T10AHE3_A/I?
The "_A/I" suffix in SM15T10AHE3_A/I indicates the packaging configuration: "A" denotes the base device variant (unidirectional, 10 V VWM), and "I" specifies 13-inch plastic tape-and-reel delivery with 3500 units per reel, per Vishay's ordering information table in document 88380.
How does SM15T10AHE3_A/I differ from SM15T10A-E3/57T?
SM15T10AHE3_A/I is AEC-Q101 qualified and supplied in 13″ tape-and-reel (3500 pcs), whereas SM15T10A-E3/57T is commercial-grade only and shipped in 7″ tape-and-reel (850 pcs). Both share identical electrical specs and SMC package, but only SM15T10AHE3_A/I carries automotive reliability validation.
What is the maximum operating temperature for SM15T10AHE3_A/I?
The SM15T10AHE3_A/I has a maximum junction temperature (TJ max) of +150 °C, enabling reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in Figure 2 of datasheet 88380 define allowable power reduction above TA = 25 °C.
