Product details
Overview
TA6F24AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode in SlimSMA (DO-221AC) package, rated for 24.0 V breakdown voltage (VBR), 20.5 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs). It delivers clamping voltage of 33.2 V at 5.0 A peak pulse current and operates up to +185 °C junction temperature, making it suitable for automotive sensor line protection under inductive switching transients.
For engineers reviewing the TA6F24AHM3_A/H datasheet, TA6F24AHM3_A/H pinout, TA6F24AHM3_A/H application, or TA6F24AHM3_A/H equivalent, this device is selected for high-reliability AEC-Q101-compliant transient suppression where low-profile mounting (<0.95 mm height), 30 kV IEC 61000-4-2 ESD robustness, and MSL Level 1 reflow compatibility are required.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for stable clamping performance across -65 °C to +185 °C. Its unidirectional architecture provides reverse-biased transient suppression only, requiring correct polarity alignment (cathode band marked) in series with protected signal or power lines.
The SlimSMA (DO-221AC) package enables automated placement and achieves RθJA = 120–150 °C/W on FR4 PCB with minimum recommended pad layout. Thermal resistance junction-to-mount (RθJM) is 12–15 °C/W, supporting sustained 8 W power dissipation at TM = 65 °C under defined thermal conditions.
Key Specifications

Applications
| Automotive Sensor Protection | Power Supply Input Clamping |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive switching transients in engine control units. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground to clamp negative-going transients and absorb surge energy. Use Value: Limits voltage excursion to ≤33.2 V during 5.0 A surges, preventing latch-up or gate oxide damage in 3.3 V/5 V interface ICs. |
Use Scenario: Safeguarding 24 V DC input rails of ADAS domain controllers and body control modules against ISO 7637-2 pulse 1/2a/5a transients. IC Role / Device Role / Timing Role: Primary front-end transient suppressor mounted directly at connector entry point, shunting surge current to chassis ground. Use Value: Withstands 600 W peak pulse power and operates up to +185 °C, ensuring protection integrity during extended high-temperature operation. |
| Industrial Motor Drive Feedback Lines | Automotive Lighting Control |
Use Scenario: Shielding encoder quadrature signals and current-sense amplifier inputs from commutation noise in BLDC motor drives. IC Role / Device Role / Timing Role: Low-capacitance TVS (CJ < 100 pF at VWM) placed inline with differential pairs to avoid signal integrity degradation. Use Value: Maintains signal fidelity while clamping fast-rising transients (tr = 10 μs) to safe levels below receiver absolute maximum ratings. |
Use Scenario: Suppressing voltage spikes induced by relay switching and PWM dimming in LED headlamp driver modules. IC Role / Device Role / Timing Role: Unidirectional TVS connected across LED string anode-cathode to prevent reverse-bias overstress during turn-off transients. Use Value: 20.5 V VWM allows normal 12 V/24 V operation while clamping >30 V spikes, extending LED driver MOSFET lifetime. |
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 | Same VBR (24.0 V typ), but rated for 400 W PPPM and uses SMA package (1.7 mm height) | Larger footprint and height limit use in ultra-thin modules; lower surge rating reduces margin in harsh automotive environments | Select when cost sensitivity outweighs height constraints and 400 W surge capacity suffices |
| TPSMD24 | Same SlimSMA package and 600 W rating, but bidirectional configuration (VRWM = 24 V, symmetrical clamping) | Required for AC-coupled or dual-polarity signal lines; adds ~15% capacitance vs. unidirectional TA6F24AHM3_A/H | Select for differential bus protection (e.g., RS-485) where polarity reversal must be suppressed |
Compared with SMAJ24A and TPSMD24, TA6F24AHM3_A/H offers optimal balance of ultra-low profile (0.95 mm), AEC-Q101 qualification, and full 600 W surge capability in unidirectional configuration-making it preferred for space-limited, high-reliability automotive signal line protection.

FAQ
What is the exact breakdown voltage tolerance for TA6F24AHM3_A/H?
The TA6F24AHM3_A/H has a specified breakdown voltage range of 22.8 V (minimum) to 25.2 V (maximum) at 1.0 mA test current, with 24.0 V nominal. This ±5% tolerance ensures consistent clamping behavior across production lots while maintaining margin against system operating voltage.
Is TA6F24AHM3_A/H compatible with lead-free reflow processes?
Yes, TA6F24AHM3_A/H is qualified for lead-free reflow with a maximum peak temperature of 260 °C per J-STD-020, classified as MSL Level 1. Its matte tin-plated terminals and halogen-free molding compound ensure reliable solder joint formation without voiding or intermetallic issues.
Does TA6F24AHM3_A/H support bidirectional transient suppression?
No, TA6F24AHM3_A/H is unidirectional. It clamps only reverse-biased transients (anode negative relative to cathode). For bidirectional protection, consider the TPSMD24 variant, which shares the same SlimSMA package but provides symmetrical clamping around 0 V.
What is the maximum clamping voltage of TA6F24AHM3_A/H under surge conditions?
The TA6F24AHM3_A/H exhibits a maximum clamping voltage (VC) of 33.2 V when subjected to a 5.0 A peak pulse current with a 10/1000 μs waveform. This value is measured per standard test conditions and defines the upper voltage limit imposed on protected circuitry during transient events.
How does TA6F24AHM3_A/H perform at elevated junction temperatures?
TA6F24AHM3_A/H maintains specified performance up to +185 °C junction temperature. Its VBR exhibits a positive temperature coefficient of +0.085 %/°C, meaning breakdown voltage increases linearly with temperature-ensuring stable, predictable clamping behavior in under-hood automotive applications.
