Product details
Overview
TA6F36AHM3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SlimSMA (DO-221AC) package, rated for 36.0 V breakdown voltage (VBR), 30.8 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 12.0 V clamping voltage at 49.9 A peak surge current, and qualified to AEC-Q101 for automotive electronics protection.
For engineers reviewing the TA6F36AHM3_A/H datasheet, TA6F36AHM3_A/H pinout, TA6F36AHM3_A/H application, or TA6F36AHM3_A/H equivalent, this device serves as a high-reliability, low-profile (0.95 mm height) ESD and surge protector for automotive sensor signal lines, MOSFET gate drivers, and IC power rails where TJ = 185 °C operation and IEC 61000-4-2 ±30 kV ESD immunity are required.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for stable clamping under repetitive transients. Its unidirectional configuration provides reverse-biased overvoltage protection while maintaining low leakage (<1.0 µA at VWM) and tight VBR tolerance (±5% typical).
Designed for high-temperature reliability, TA6F36AHM3_A/H achieves 185 °C maximum junction temperature and meets MSL Level 1 (260 °C reflow peak). Thermal resistance is 120–150 °C/W (junction-to-ambient) on FR4 PCB with minimum recommended pad layout, enabling robust thermal performance in compact automotive modules.

Use Scenario: Protecting analog output lines of pressure, temperature, and position sensors in engine control units exposed to load-dump and inductive switching noise. IC Role / Device Role / Timing Role: TVS diode placed between sensor output and ECU input to clamp fast transients before they reach precision ADC front-end. Use Value: Maintains signal integrity with <1.0 µA leakage at 30.8 V and clamps to 12.0 V during 49.9 A surges, preventing ADC saturation or latch-up. |
Use Scenario: Safeguarding 3.3 V or 5 V microcontroller supply rails in body control modules subject to battery line transients. IC Role / Device Role / Timing Role: Unidirectional TVS connected from VCC to GND to shunt positive-going spikes exceeding VWM. Use Value: 600 W peak power rating and 185 °C junction rating allow sustained operation in under-hood environments without thermal shutdown. |
| MOSFET Gate Protection | Infotainment Interface Lines |
|
Use Scenario: Shielding high-side N-channel MOSFET gates in LED driver circuits from voltage overshoot during PWM switching. IC Role / Device Role / Timing Role: TVS placed between gate and source to limit dV/dt-induced gate oxide stress and prevent false turn-on. Use Value: Tight VBR tolerance (±5%) and low clamping voltage (12.0 V) ensure gate voltage stays within safe SOA limits even during 10/1000 µs surges. |
Use Scenario: ESD hardening of LIN bus or CAN FD physical layer signal lines in dashboard displays and head units. IC Role / Device Role / Timing Role: Discrete TVS on each differential line to absorb contact/air discharge per IEC 61000-4-2 up to ±30 kV. Use Value: SlimSMA footprint allows placement directly at connector entry point; 0.95 mm height avoids interference with shield cans and stacked PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A-E3/5A (Vishay) | Same VBR (36 V), but SMA package (DO-214AC); RθJA = 140 °C/W vs. 120–150 °C/W; height 2.3 mm vs. 0.95 mm | Less suitable for ultra-low-profile automotive modules; higher thermal resistance requires larger copper area for same power dissipation | Select TA6F36AHM3_A/H when board height ≤1.0 mm is mandatory and AEC-Q101 + MSL Level 1 are required |
| TPSMD36CA (Texas Instruments) | Bi-directional configuration; same VBR and PPPM, but higher VC (13.4 V); not AEC-Q101 qualified | Applicable only where symmetrical AC-coupled signals require bidirectional clamping; lacks automotive qualification evidence | Choose TA6F36AHM3_A/H for unidirectional DC systems requiring certified automotive reliability and lower clamping voltage |
Compared with SMAJ36A-E3/5A and TPSMD36CA, TA6F36AHM3_A/H delivers superior height reduction (0.95 mm), verified AEC-Q101 compliance, and tighter clamping (12.0 V), making it optimal for next-generation automotive ECUs where space, reliability, and precise voltage limiting are critical.

The TA6F36AHM3_A/H has a specified breakdown voltage range of 34.2 V (min) to 37.8 V (max) at 1.0 mA test current, corresponding to ±5% tolerance around the nominal 36.0 V value. This tight tolerance ensures predictable clamping behavior across production lots and temperature ranges, critical for protecting sensitive automotive electronics without premature conduction.
Is TA6F36AHM3_A/H compatible with lead-free reflow soldering processes?
Yes, TA6F36AHM3_A/H is rated for MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD22-B102, and the SlimSMA package passes JESD201 Class 2 whisker testing, making it fully compatible with standard lead-free SMT assembly lines.
Does TA6F36AHM3_A/H meet automotive qualification standards?
Yes, TA6F36AHM3_A/H is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet (Document Number: 89939, Revision: 16-Jan-2025). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and ESD, validating its suitability for automotive powertrain, chassis, and body electronics applications.
What is the maximum clamping voltage of TA6F36AHM3_A/H at rated surge current?
The maximum clamping voltage (VC) of TA6F36AHM3_A/H is 12.0 V at the rated peak pulse current (IPPM) of 49.9 A under a 10/1000 µs waveform. This low clamping level ensures downstream components such as microcontrollers and analog sensors remain within safe operating voltage limits during severe transients.
How does the thermal performance of TA6F36AHM3_A/H compare to standard SMA packages?
TA6F36AHM3_A/H offers improved thermal resistance versus traditional SMA packages: RθJA is 120–150 °C/W on FR4 with minimum pad layout, compared to ~140–180 °C/W for SMAJ-series devices. Its SlimSMA (DO-221AC) construction and optimized thermal path enable higher power dissipation in confined spaces, supporting continuous operation at elevated ambient temperatures.
