Product details
Overview
TA6L15AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SlimSMAW (DO-221AD) package, designed for automotive-grade overvoltage protection. It features 15.0 V nominal breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), 28.3 V maximum clamping voltage (VC) at 21.2 A peak pulse current, 600 W peak pulse power (10/1000 µs), and 185 °C maximum junction temperature - enabling robust protection of MOSFETs and sensor signal lines in high-reliability automotive ECUs.
For engineers reviewing the TA6L15AHM3/I datasheet, TA6L15AHM3/I pinout, TA6L15AHM3/I application, or TA6L15AHM3/I equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, SlimSMAW package dimensions, thermal derating curves, and direct alternatives with documented clamping and leakage differences.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable breakdown behavior up to TJ = 185 °C and meets JESD201 Class 2 whisker test requirements (HM3 suffix). Its unidirectional configuration provides low-leakage reverse blocking (1.0 µA at VWM) and precise clamping response under fast transients.
The device operates within -65 °C to +185 °C junction temperature range, exhibits 0.076 %/°C temperature coefficient of VBR, and is rated for 600 W peak pulse power with 10/1000 µs waveform - validated per ANSI/IEEE C62.35 standards and JEDEC 51-2A thermal testing on FR4 PCB.

Applications
| Automotive Engine Control Unit (ECU) | Automotive Sensor Signal Protection |
|---|---|
Use Scenario: Protecting 12 V supply rails in engine management systems against ISO 7637-2 pulse 5a (load dump) transients. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed between battery input and LDO regulator input. Use Value: Limits transient voltage to ≤28.3 V, preventing LDO overvoltage failure and ensuring uninterrupted MCU operation during cranking events. |
Use Scenario: Safeguarding analog outputs of pressure or temperature sensors connected to vehicle CAN networks. IC Role / Device Role / Timing Role: TVS placed across sensor output line and chassis ground to absorb ESD and switching noise. Use Value: Maintains signal integrity below 1.0 µA leakage at 12.8 V, avoiding DC offset errors in precision 4–20 mA loops. |
| Automotive Body Control Module (BCM) | Industrial Motor Drive Feedback Protection |
Use Scenario: Shielding LIN bus transceivers and window motor drivers from inductive kickback in door modules. IC Role / Device Role / Timing Role: TVS installed at motor driver output pins to clamp flyback spikes before reaching logic-level gate drivers. Use Value: Withstands 21.2 A peak surge at 28.3 V clamping, preventing latch-up in 3.3 V microcontroller I/O ports. |
Use Scenario: Protecting encoder quadrature signals in servo drives exposed to EMI from adjacent IGBT switching. IC Role / Device Role / Timing Role: TVS mounted directly at connector interface to shunt common-mode transients before entering differential receiver. Use Value: 0.076 %/°C VBR tempco ensures stable clamping across -40 °C to +125 °C ambient - critical for factory automation reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/5A (Vishay) | Same VBR (15.0 V typ), but lower PPPM = 400 W and higher VC = 24.4 V at 17.2 A; DO-214AC package | Limited to lower-energy transients; not AEC-Q101 qualified; unsuitable for automotive under-hood use | Select SMAJ15A-E3/5A only for cost-sensitive industrial controls where AEC-Q101 and 600 W rating are unnecessary |
| 1.5SMC15A (ON Semiconductor) | Identical VBR/VC specs, but rated for 150 °C TJ max and lacks JESD201 whisker test validation; DO-214AB package | Not qualified for automotive under-hood environments requiring >150 °C operation or whisker resistance | Choose 1.5SMC15A only for non-automotive applications where 185 °C capability and Class 2 whisker immunity are not required |
Compared with SMAJ15A-E3/5A and 1.5SMC15A, TA6L15AHM3/I delivers higher surge robustness (600 W vs. 400 W/1500 W), extended junction temperature margin (+185 °C), and automotive-specific process validation - making it the sole option qualified for engine compartment deployment with zero layout change from standard SlimSMAW footprints.

FAQ
What is the clamping voltage of TA6L15AHM3/I at its rated peak pulse current?
The TA6L15AHM3/I has a maximum clamping voltage (VC) of 28.3 V when subjected to its rated peak pulse current of 21.2 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that protected circuitry sees no more than 28.3 V during worst-case surge events - critical for safeguarding 3.3 V or 5 V logic interfaces downstream of the TA6L15AHM3/I.
Is TA6L15AHM3/I qualified for automotive applications?
Yes, TA6L15AHM3/I is AEC-Q101 qualified and carries the HM3 suffix indicating compliance with JESD201 Class 2 whisker testing. It is rated for continuous operation up to 185 °C junction temperature and meets automotive reliability requirements for engine control, body electronics, and sensor modules - confirmed in Vishay Document Number 87415, Revision 17-Sep-2021.
What package type does TA6L15AHM3/I use, and what are its key mechanical attributes?
TA6L15AHM3/I uses the SlimSMAW (DO-221AD) package: a low-profile surface-mount case with 2.70 mm × 4.00 mm outline, UL 94 V-0 molding compound, matte tin-plated leads, and MSL Level 1 rating (260 °C peak reflow). Its cathode is marked by a visible band, and it is optimized for high-density automotive PCB layouts requiring minimal board space and high thermal reliability.
How does the temperature coefficient of breakdown voltage affect TA6L15AHM3/I performance?
The TA6L15AHM3/I has a typical temperature coefficient of VBR of +0.076 %/°C. This means its breakdown voltage increases linearly with junction temperature - e.g., rising ~1.14 V from 25 °C to 175 °C. Designers must account for this shift when setting safety margins in high-ambient environments, especially in under-hood automotive applications where sustained 150 °C+ operation is common.
What is the maximum reverse leakage current of TA6L15AHM3/I at its stand-off voltage?
At its 12.8 V stand-off voltage (VWM) and 25 °C ambient, TA6L15AHM3/I exhibits a maximum reverse leakage current (IR) of 1.0 µA. At elevated temperature (TJ = 150 °C), leakage rises to 5.0 µA - still well below thresholds that would disturb sensitive analog sensor inputs or bias networks, confirming suitability for precision automotive signal conditioning paths.
