Product details
Overview
TA6F30AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SlimSMA (DO-221AC) package, rated for 30 V breakdown voltage (VBR = 28.5–31.5 V at 1 mA), 600 W peak pulse power (10/1000 μs), and 185 °C maximum junction temperature - designed for automotive-grade ESD and surge protection on signal lines and MOSFET gates.
For engineers reviewing the TA6F30AHM3_A/I datasheet, TA6F30AHM3_A/I pinout, TA6F30AHM3_A/I application, or TA6F30AHM3_A/I equivalent, this device delivers AEC-Q101 qualification, 30 kV IEC 61000-4-2 contact discharge immunity, and low-profile (0.95 mm height) compatibility with automated SMT placement in space-constrained automotive sensor modules and powertrain control units.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to achieve stable clamping under repetitive transients while maintaining low leakage (<1.0 μA at VWM = 25.6 V) and high thermal robustness (TJ up to 185 °C). Its unidirectional architecture enables precise reverse-biased overvoltage clamping without forward conduction interference.
The SlimSMA (DO-221AC) package provides optimized thermal resistance (RθJA = 120–150 °C/W, RθJM = 12–15 °C/W) and meets JESD201 Class 2 whisker resistance, MSL Level 1, and UL 94 V-0 flammability - supporting high-reliability mounting on FR4 PCBs with minimum recommended pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 28.5 / 30.0 / 31.5 V at 1 mA - defines reliable turn-on threshold for transient suppression without false triggering during normal operation |
| VWM | 25.6 V - maximum continuous reverse working voltage before leakage exceeds 1.0 μA, ensuring safe operation across automotive battery ranges |
| VC @ IPPM | 41.4 V at 14.5 A - clamping voltage during 600 W surge, limiting downstream IC stress to <42 V under worst-case 10/1000 μs transients |

Applications
| Automotive Sensor Protection | Powertrain Control Unit Inputs |
|---|---|
Use Scenario: Protecting analog outputs of pressure, temperature, and position sensors exposed to load-dump and inductive switching noise in engine bays. IC Role / Device Role / Timing Role: Unidirectional TVS clamping element placed directly at sensor connector interface to shunt transients before reaching ADC input or op-amp buffer. Use Value: Limits voltage to ≤41.4 V during 600 W surges, preserving signal integrity and preventing latch-up in 3.3 V/5 V sensor signal conditioning circuits. |
Use Scenario: Safeguarding digital inputs (e.g., crankshaft/camshaft position signals) and PWM-controlled actuator feedback lines in transmission control modules. IC Role / Device Role / Timing Role: Fast-response overvoltage clamp on microcontroller GPIO pins interfacing with external magnetic or Hall-effect sensors. Use Value: Withstands 30 kV ESD events and sub-100 ns transients without degradation, ensuring functional safety compliance (ISO 26262 ASIL-B ready). |
| Body Electronics LIN Bus Nodes | Electric Power Steering (EPS) Motor Drivers |
Use Scenario: Shielding LIN transceiver I/O pins against battery reversal, jump-start spikes, and electrostatic discharge in door modules and seat controllers. IC Role / Device Role / Timing Role: Standoff voltage (25.6 V) matches LIN bus operating range; clamps reverse polarity and ESD without interfering with 12 V nominal signaling. Use Value: Maintains <1.0 μA leakage at VWM, avoiding signal distortion or false wake-up in always-on LIN nodes. |
Use Scenario: Protecting gate drive signals and current-sense amplifier inputs in EPS motor driver ICs subjected to motor back-EMF and load dump. IC Role / Device Role / Timing Role: Placed between gate driver output and MOSFET gate to clamp Miller-induced voltage spikes and prevent unintended turn-on. Use Value: 185 °C junction rating ensures stable clamping performance during sustained high-temperature EPS operation (e.g., >125 °C ambient). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ30A (ON Semiconductor) | Same VBR range (28.5–31.5 V), but SMB (DO-214AA) package (1.7 mm height); RθJA = 190 °C/W vs. 120–150 °C/W for TA6F30AHM3_A/I | Larger footprint and height limit use in ultra-thin modules; lower thermal performance reduces surge margin at elevated ambient temperatures | Select when legacy SMB layout exists and height constraint is not critical; avoid for new AEC-Q101 designs requiring SlimSMA footprint |
| TPSMA6L30A (Texas Instruments) | Identical SlimSMA (DO-221AC) package and VBR/VC specs, but rated for 150 °C TJ max (vs. 185 °C) and lacks AEC-Q101 certification | Not qualified for automotive under-hood use; suitable only for industrial or consumer applications with lower thermal/stress requirements | Acceptable for non-automotive designs where cost is prioritized over extended temperature capability and qualification traceability |
Compared with SMBJ30A and TPSMA6L30A, TA6F30AHM3_A/I offers superior thermal robustness (185 °C TJ), verified AEC-Q101 qualification, and lowest profile among equivalents - making it the preferred choice for next-generation automotive ECUs demanding high-density packaging and extended lifetime under thermal stress.
