Product details
Overview
TA6F13AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SlimSMA (DO-221AC) package, with 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs). It delivers 33.0 V clamping voltage at 5.0 A peak pulse current and operates up to +185 °C junction temperature - designed for automotive sensor line protection against load dump and ESD.
For engineers reviewing the TA6F13AHM3_A/I datasheet, TA6F13AHM3_A/I pinout, TA6F13AHM3_A/I application, or TA6F13AHM3_A/I equivalent, this page provides verified electrical parameters, AEC-Q101 qualification status, thermal resistance values (RθJA = 120–150 °C/W), IEC 61000-4-2 ±30 kV ESD rating, and SlimSMA mechanical dimensions for layout validation and high-reliability automotive design review.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable breakdown behavior across temperature, with a typical temperature coefficient of VBR at +0.072 %/°C. Its unidirectional configuration enables precise reverse-biased clamping on signal or power rails where polarity is fixed.
The device is rated for 600 W peak pulse power under 10/1000 μs waveform, with clamping performance validated at 33.0 V @ 5.0 A. Thermal design is supported by RθJM = 12–15 °C/W (junction-to-mount) and compatibility with JESD22-B102 soldering standards on FR4 PCBs using minimum recommended pad layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Same VWM (11.1 V) and VC (33.0 V), but lower PPPM (400 W) and TJ max (150 °C); DO-214AC package (1.6 mm height) | Limited to under-dash modules; not qualified to AEC-Q101; unsuitable for engine compartment use | Select SMAJ13A only for cost-sensitive non-automotive industrial designs where 400 W surge rating suffices. |
| TPSMF13A | Identical VBR/VC/PPPM, but SOD-123FL package (1.3 mm height); AEC-Q101 qualified; RθJA = 170 °C/W (higher thermal resistance) | Higher thermal impedance limits power density in high-ambient-temperature zones; smaller footprint may ease routing | Choose TPSMF13A when board space is critical and thermal margin allows higher junction rise per watt. |
Compared with SMAJ13A and TPSMF13A, the TA6F13AHM3_A/I offers superior thermal robustness (185 °C TJ max, RθJA ≤ 150 °C/W) and ultra-low profile (0.95 mm), making it the preferred choice for AEC-Q101-compliant automotive front-end protection where both reliability and height constraints apply.

FAQ
What is the clamping voltage of the TA6F13AHM3_A/I at its rated peak pulse current?
The TA6F13AHM3_A/I has a maximum clamping voltage (VC) of 33.0 V at 5.0 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per the standard test method defined in the Vishay datasheet and ensures predictable voltage limiting during surge events. The TA6F13AHM3_A/I maintains this clamping performance across its full operating temperature range up to +185 °C junction temperature.
Is the TA6F13AHM3_A/I qualified for automotive applications?
Yes, the TA6F13AHM3_A/I is AEC-Q101 qualified, meaning it has passed rigorous stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing. Its 185 °C maximum junction temperature, halogen-free construction, and SlimSMA package meet automotive OEM requirements for under-hood and safety-critical systems. The TA6F13AHM3_A/I is explicitly listed in Vishay's AEC-Q101 qualified product list.
What does the "HM3_A/I" suffix indicate in TA6F13AHM3_A/I?
The "HM3" denotes the SlimSMA (DO-221AC) package variant with halogen-free, RoHS-compliant molding compound; "A" indicates the revision level per Vishay's internal documentation; "I" specifies the tape-and-reel packaging format - 13-inch diameter reel containing 14,000 units. This differs from the "H" variant (7-inch reel, 3500 units). The TA6F13AHM3_A/I is fully compatible with standard SMT pick-and-place equipment calibrated for DO-221AC footprints.
How does the TA6F13AHM3_A/I compare to standard SMAJ series TVS diodes?
The TA6F13AHM3_A/I provides identical electrical clamping performance (VWM = 11.1 V, VC = 33.0 V) as SMAJ13A but with higher peak pulse power (600 W vs. 400 W), extended junction temperature rating (+185 °C vs. +150 °C), and lower profile (0.95 mm vs. 1.6 mm). Unlike SMAJ13A, the TA6F13AHM3_A/I is AEC-Q101 qualified and built on passivated anisotropic rectifier technology for improved long-term stability. These advantages make the TA6F13AHM3_A/I suitable for next-generation automotive platforms where thermal and spatial constraints are tighter.
What is the ESD withstand capability of the TA6F13AHM3_A/I?
The TA6F13AHM3_A/I meets IEC 61000-4-2 with ±30 kV contact discharge and ±30 kV air discharge ratings - among the highest ESD immunity levels for surface-mount TVS diodes. This performance is achieved through optimized junction passivation and low-leakage design, enabling direct protection of sensitive analog and digital inputs in automotive sensor nodes. The TA6F13AHM3_A/I maintains this ESD rating across its full -65 °C to +185 °C operating temperature range without degradation.
