Product details
Overview
T4F13AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor in SMF (DO-219AB) package, rated for 13.0 V nominal breakdown voltage (VBR), 11.1 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 μs), and 185 °C maximum junction temperature - designed for automotive-grade overvoltage protection of sensor signal lines and MOSFET gates.
For engineers reviewing the T4F13AHM3/H datasheet, T4F13AHM3/H pinout, T4F13AHM3/H application, or T4F13AHM3/H equivalent, key selection criteria include its AEC-Q101 qualification, TJ = 185 °C capability, 18.2 V clamping voltage at 22.0 A IPPM, unidirectional polarity, and SOD-123W-compatible SMF package footprint.
Technical Context
The T4F13AHM3/H employs passivated anisotropic rectifier technology with junction passivation optimized for high-reliability operation under thermal stress. It delivers stable clamping performance across -65 °C to +185 °C junction temperature range and supports wave and reflow soldering per J-STD-020 MSL level 1 (260 °C peak).
Its electrical behavior follows ANSI/IEEE C62.35 standards, with VBR measured at 1.0 mA IT after 300 μs square-wave pulse. The device exhibits a +0.072 %/°C temperature coefficient of breakdown voltage and achieves 18.2 V clamping at 22.0 A peak pulse current under 10/1000 μs waveform.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-HF | Same VBR (13.0 V), but SMA package (DO-214AC); RthJA = 150 °C/W vs. 135 °C/W for T4F13AHM3/H | Higher thermal resistance limits power handling in confined PCB areas | Select when legacy SMA footprint compatibility is required over thermal performance |
| 1.5SMC13A | Higher PPPM (1500 W), but larger SMC (DO-214AB) package; VC = 21.2 V at 70.1 A | Clamps at higher voltage, reducing margin for 12 V logic interfaces | Prefer for high-energy industrial surge zones where board space allows larger case |
Compared with SMAJ13A-HF and 1.5SMC13A, the T4F13AHM3/H offers superior thermal performance in a smaller footprint and tighter clamping voltage - critical for modern automotive sensor nodes where space, temperature, and signal integrity are constrained.

FAQ
What is the clamping voltage of the T4F13AHM3/H at its rated peak pulse current?
The T4F13AHM3/H has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current (IPPM) of 22.0 A under a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures safe operation for 12 V automotive circuits. The T4F13AHM3/H maintains this clamping performance across its full operating temperature range.
Is the T4F13AHM3/H qualified for automotive applications?
Yes, the T4F13AHM3/H is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and other high-reliability automotive applications. Its construction meets MSL Level 1 per J-STD-020, and the HM3 suffix confirms halogen-free, RoHS-compliant, and whisker-resistant plating - all verified per Vishay's qualification report for the T4F13AHM3/H.
What package type does the T4F13AHM3/H use, and is it compatible with automated assembly?
The T4F13AHM3/H uses the SMF (DO-219AB) package, a low-profile surface-mount case with 0.85 mm height and SOD-123W-compatible footprint. It is fully compatible with standard wave and reflow soldering processes, including lead-free reflow profiles up to 260 °C peak, and meets J-STD-002 and JESD 22-B102 solderability requirements for automated assembly of the T4F13AHM3/H.
How does the temperature coefficient affect the breakdown voltage of the T4F13AHM3/H?
The T4F13AHM3/H has a typical temperature coefficient (αT) of +0.072 %/°C for its breakdown voltage. This means VBR increases by approximately 0.0094 V per °C rise above 25 °C. For example, at 150 °C, VBR rises to ~13.9 V - a predictable shift used in margining designs that rely on the T4F13AHM3/H for precision clamping.
What is the maximum reverse leakage current of the T4F13AHM3/H at its stand-off voltage?
At its stand-off voltage (VWM) of 11.1 V and ambient temperature of 25 °C, the T4F13AHM3/H exhibits a maximum reverse leakage current (ID) of 1.0 μA. At elevated temperature (TJ = 150 °C), leakage remains ≤ 5.0 μA - low enough to avoid loading sensitive sensor outputs or microcontroller inputs in systems using the T4F13AHM3/H.
