Product details
Overview
TA6L24AHM3/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SlimSMAW (DO-221AD) package, designed for automotive-grade circuit protection. It features a 24.0 V nominal breakdown voltage (VBR), 20.5 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 18.1 A peak pulse current (IPPM), and 33.2 V maximum clamping voltage (VC) - deployed to safeguard MOSFETs and sensor signal lines against inductive switching transients.
For engineers reviewing the TA6L24AHM3/H datasheet, TA6L24AHM3/H pinout, TA6L24AHM3/H application, or TA6L24AHM3/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, SlimSMAW mechanical dimensions, and direct alternatives with documented clamping and leakage differences.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for junction stability up to TJ = 185 °C, enabling operation in high-reliability automotive environments. Its unidirectional configuration provides low-leakage reverse blocking (1.0 µA at VWM) and precise clamping response under 10/1000 µs surge waveforms.
The device is housed in a halogen-free, RoHS-compliant SlimSMAW (DO-221AD) package with matte tin-plated leads, rated MSL Level 1 and qualified to JESD22-B102 solderability standards. Thermal resistance is RθJA = 120–150 °C/W on FR4 PCB per JEDEC 51-2A.
Key Specifications

|---|---|
| VBR (min/typ/max) | 22.8 / 24.0 / 25.2 V - ensures reliable conduction onset above system operating voltage while avoiding false triggering |
| VWM | 20.5 V - maximum continuous reverse voltage before significant leakage begins; matches 24 V automotive supply rails |
| IPPM | 18.1 A - peak surge current capability under standardized 10/1000 µs waveform, defining robustness against load dump |
| VC | 33.2 V - clamped voltage during IPPM, limiting stress on downstream ICs and MOSFETs |
| TJ max | +185 °C - enables sustained operation in engine bay or powertrain control units without thermal shutdown |
| Package | SlimSMAW (DO-221AD) - low-profile surface-mount outline with 0.197" × 0.142" footprint and 0.032" height for space-constrained PCB layouts |
Pinout & Package
SlimSMAW (DO-221AD) is a two-terminal, single-diode surface-mount package with cathode indicated by a color band. The device has no internal connections beyond anode and cathode terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction; connected to ground or low-side reference in unidirectional TVS configuration | Provides return path for surge current when cathode is held at higher potential than anode |
| Cathode | Current exit point during clamping; connected to protected line (e.g., sensor output or MOSFET gate) | Defines polarity-sensitive clamping action - only conducts when cathode voltage exceeds anode by ≥VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics use including powertrain and body control modules under stress conditions per JESD22-A108 |
| Junction temperature rating | Rated for continuous operation up to +185 °C - supports placement near heat sources without derating penalties |
| Low-profile SlimSMAW package | 0.032" height enables integration into compact ECUs and ADAS sensor housings where Z-axis clearance is constrained |
| Halogen-free & RoHS-compliant | Meets automotive environmental compliance requirements including ELV Directive and OEM material declarations |
| MSL Level 1 rating | Allows unlimited floor life and reflow at 260 °C peak - eliminates baking requirements prior to assembly |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/5T | VC = 38.9 V (higher clamping), VWM = 20.5 V same, IPPM = 15.4 A (lower surge current) | Less effective clamping margin for 24 V systems with tight downstream voltage tolerances | Select SMAJ24A-E3/5T only if board layout requires SMA package and clamping margin >5 V is acceptable |
| TPSMF24A | VC = 35.5 V, VWM = 20.5 V, IPPM = 16.9 A, RθJA = 130 °C/W (slightly higher thermal resistance) | Lower peak power rating (400 W vs. 600 W) limits suitability for high-energy load dump scenarios | Prefer TP-SMF24A only when cost sensitivity outweighs need for full 600 W surge capacity in non-critical subsystems |
Compared with SMAJ24A-E3/5T and TPSMF24A, TA6L24AHM3/H delivers superior surge robustness (600 W/18.1 A) and tighter clamping (33.2 V), making it optimal for AEC-Q101-compliant 24 V automotive power domains where voltage margin and thermal endurance are critical.

FAQ
What is the clamping voltage of the TA6L24AHM3/H under peak pulse conditions?
The TA6L24AHM3/H has a maximum clamping voltage (VC) of 33.2 V when subjected to its rated peak pulse current (IPPM) of 18.1 A using the standard 10/1000 µs waveform. This value is measured per Figure 3 in the official Vishay datasheet (Document Number: 87415) and defines the upper voltage limit imposed on protected circuits during surge events. The TA6L24AHM3/H maintains this clamping performance across its full operating temperature range.
Is the TA6L24AHM3/H qualified for automotive applications?
Yes, the TA6L24AHM3/H is AEC-Q101 qualified and meets JESD22-A108 stress testing requirements for automotive electronics. Its HM3 suffix indicates halogen-free, RoHS-compliant construction and JESD201 Class 2 whisker resistance. The device operates reliably from -65 °C to +185 °C junction temperature, satisfying under-hood and powertrain placement requirements. TA6L24AHM3/H is explicitly listed in Vishay's automotive-grade product portfolio.
What package type does the TA6L24AHM3/H use, and what are its key mechanical attributes?
The TA6L24AHM3/H uses the SlimSMAW (DO-221AD) package: a low-profile surface-mount outline measuring 5.00 mm × 3.60 mm × 0.81 mm (L × W × H), with a cathode band marking and matte tin-plated leads. It complies with MSL Level 1 per J-STD-020 and supports 260 °C lead-free reflow. The SlimSMAW footprint allows high-density PCB layouts while maintaining thermal performance via optimized copper pad design per JEDEC 51-2A.
How does the TA6L24AHM3/H compare to standard SMAJ-series TVS diodes in terms of surge capability?
The TA6L24AHM3/H delivers 600 W peak pulse power (10/1000 µs), exceeding the 400 W rating of SMAJ24A-E3/5T. Its IPPM is 18.1 A versus 15.4 A for SMAJ24A-E3/5T, and its VC is lower at 33.2 V versus 38.9 V - resulting in tighter voltage limiting and greater energy-handling margin. These advantages stem from the TA6L24AHM3/H's optimized passivated anisotropic rectifier structure and SlimSMAW thermal design.
What is the reverse leakage current specification for the TA6L24AHM3/H at its stand-off voltage?
The TA6L24AHM3/H exhibits a maximum reverse leakage current (IR) of 1.0 µA at its stand-off voltage (VWM) of 20.5 V, tested at TA = 25 °C. At elevated temperature (TJ = 150 °C), leakage increases to 5.0 µA - still well within safe operating limits for protecting sensitive analog and digital inputs. This low-leakage behavior is confirmed in Table 1 of the Vishay datasheet (87415) and supports precision sensor interface designs.
