Product details
Overview
TA6F16AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SlimSMA (DO-221AC) package, rated for 16.0 V breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the TA6F16AHM3_A/I datasheet, TA6F16AHM3_A/I pinout, TA6F16AHM3_A/I application, or TA6F16AHM3_A/I equivalent, this device serves as a high-reliability clamping diode for inductive load switching transients on sensor signal lines, MOSFET gate drivers, and IC power rails under high-temperature conditions up to TJ = 185 °C.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for stable clamping performance across temperature. Its unidirectional configuration provides low-clamp-voltage protection against positive-going transients while maintaining <1.0 μA reverse leakage at VWM = 13.6 V and TJ = 150 °C.
The SlimSMA (DO-221AC) package enables automated placement and meets MSL Level 1 (260 °C peak reflow), JESD201 Class 2 whisker resistance, and UL 94 V-0 flammability. Thermal resistance is RθJA = 120–150 °C/W (FR4 board, minimum pad layout).

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Same VBR range (16.0 V typ), but lower PPPM = 400 W; RθJA = 160 °C/W; not AEC-Q101 qualified | Limited to commercial/industrial use; unsuitable for automotive under-hood deployment | Select when cost sensitivity outweighs automotive qualification and thermal derating requirements |
| TPSMF16A | Same SlimSMA package and AEC-Q101 rating, but higher VC = 28.5 V at IPPM; slightly lower IPPM = 37.5 A | Acceptable for less stringent clamping margins; may require layout review for thermal dissipation | Choose if existing design uses TPSMF series and board space/layout reuse is prioritized |
Compared with SMAJ16A and TPSMF16A, the TA6F16AHM3_A/I delivers superior thermal capability (TJ = 185 °C), tighter VBR tolerance (±2.5%), and lower clamping voltage (26.7 V vs. ≥28.5 V), making it optimal for high-reliability automotive signal-line protection where voltage margin and lifetime stability are critical.

FAQ
What is the breakdown voltage tolerance for TA6F16AHM3_A/I?
The TA6F16AHM3_A/I has a specified breakdown voltage range of 15.2 V (min) to 16.8 V (max) at 1.0 mA test current, yielding a ±2.5% tolerance around the nominal 16.0 V value. This tight VBR distribution ensures consistent clamping behavior across production lots and supports precise circuit margining in automotive applications.
Is TA6F16AHM3_A/I compatible with lead-free reflow processes?
Yes, the TA6F16AHM3_A/I is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated terminals meet J-STD-002 solderability requirements, and the SlimSMA package is qualified for standard lead-free reflow profiles without preconditioning or special handling.
Does TA6F16AHM3_A/I support bidirectional transient suppression?
No, the TA6F16AHM3_A/I is a unidirectional TVS diode designed to clamp only positive-going transients relative to ground. It must be oriented with the cathode band toward the protected line. For bidirectional protection, a separate device such as the TA6F16CA or a back-to-back configuration would be required.
What is the maximum clamping voltage of TA6F16AHM3_A/I under surge conditions?
The TA6F16AHM3_A/I exhibits a maximum clamping voltage (VC) of 26.7 V when subjected to its rated 41.4 A peak pulse current (IPPM) using the 10/1000 μs waveform. This value is guaranteed across temperature and ensures downstream components remain within safe operating voltage limits during surge events.
How does TA6F16AHM3_A/I perform at elevated junction temperatures?
The TA6F16AHM3_A/I maintains full functionality up to TJ = 185 °C, with VBR exhibiting a temperature coefficient of +0.078 %/°C. At 150 °C, reverse leakage remains ≤1.0 μA at VWM = 13.6 V, confirming stable performance in under-hood automotive environments and high-power industrial enclosures.
