Product details
Overview
TA6F7.5AHM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) in SlimSMA (DO-221AC) package, designed for automotive-grade circuit protection. It features a 7.5 V nominal breakdown voltage (VBR), 600 W peak pulse power (10/1000 μs), and AEC-Q101 qualification - enabling robust clamping of inductive switching transients on sensor signal lines and MOSFET gate drivers.
For engineers reviewing the TA6F7.5AHM3_A/I datasheet, TA6F7.5AHM3_A/I pinout, TA6F7.5AHM3_A/I application, or TA6F7.5AHM3_A/I equivalent, this device delivers verified 11.3 V clamping voltage at 53.1 A peak pulse current, 0.052 %/°C temperature coefficient of VBR, and 185 °C maximum junction temperature - critical for high-reliability automotive electronics under thermal stress.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable breakdown behavior and low leakage (<250 μA at VWM = 6.4 V, TJ = 150 °C). Its unidirectional polarity and cathode band marking align with standard PCB layout conventions for reverse-biased transient suppression.
The SlimSMA package enables automated placement with 0.95 mm typical height and meets MSL Level 1 per J-STD-020 (260 °C peak reflow). Thermal resistance is 120–150 °C/W (junction-to-ambient) on FR4, supporting operation up to 185 °C junction temperature without derating loss in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 7.13 / 7.50 / 7.88 V at 10 mA - defines precise overvoltage triggering threshold for reliable system-level surge response |
| VWM | 6.40 V - maximum continuous working voltage before leakage rises; ensures no false triggering during normal 5 V or 6.4 V rail operation |
| VC @ IPPM | 11.3 V at 53.1 A - clamping voltage under 600 W 10/1000 μs surge; limits downstream IC stress to safe levels |
| PPPM | 600 W (10/1000 μs) - standardized surge energy handling capacity validated per IEC 61000-4-5 |
| TJ max | 185 °C - enables use in under-hood automotive environments without thermal shutdown or parameter drift |
| ESD Rating | 30 kV contact/air per IEC 61000-4-2 - provides system-level ESD immunity without external shielding |
| AEC-Q101 | Qualified - confirms reliability for automotive applications including engine control, ADAS sensors, and body electronics |
Pinout & Package
Package: SlimSMA (DO-221AC), surface-mount, halogen-free, RoHS-compliant, matte tin-plated terminals. Cathode identified by color band. Height: 0.95 mm typical.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-impedance return path; forms clamping loop with cathode during transient events |

Key Features
| Feature | Design Value |
|---|---|
| Junction passivation optimized design | Reduces parameter drift over time and temperature; maintains VBR stability across 1000+ hours at 150 °C |
| Very low profile (0.95 mm height) | Enables routing under connectors or in space-constrained modules such as radar front-ends and camera ECUs |
| MSL Level 1 rating | Allows single-pass reflow at 260 °C peak without moisture-induced popcorn failure or delamination |
| 185 °C junction capability | Supports direct mounting near heat sources (e.g., power converters) without thermal derating penalties |
| Halogen-free & RoHS-compliant | Fulfills automotive OEM material compliance requirements (e.g., GMW3172, Ford WSS-M99P9999-A1) |
Applications
| Automotive Sensor Protection | Power MOSFET Gate Clamp |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, and position sensors in engine control units exposed to load dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and microcontroller ADC input to clamp transients below absolute maximum ratings. Use Value: Prevents ADC saturation and latch-up during 600 W surges while maintaining <250 μA leakage at 6.4 V to avoid signal offset errors. |
Use Scenario: Clamping gate-source voltage spikes on N-channel power MOSFETs driving solenoids, fuel injectors, or relays in 12 V automotive systems. IC Role / Device Role / Timing Role: TVS connected directly across MOSFET gate and source to limit VGS to ≤11.3 V during fast-switching turn-off events. Use Value: Eliminates risk of gate oxide rupture and ensures MOSFET reliability under repetitive 53.1 A surge conditions without adding RC snubbers. |
| Infotainment Interface Lines | Body Control Module Signal Inputs |
Use Scenario: Shielding LIN bus or CAN FD physical layer inputs in head unit and display modules from ESD and cable discharge events. IC Role / Device Role / Timing Role: TVS placed on each LIN data line (e.g., LIN_TX/RX) with minimal capacitance impact due to DO-221AC geometry. Use Value: Provides 30 kV IEC 61000-4-2 ESD protection while maintaining signal integrity - no measurable rise-time degradation on 20 kbps LIN signals. |
Use Scenario: Protecting digital inputs (e.g., door lock switch, window lift feedback) in BCMs against battery reversal and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS installed on each input line referenced to chassis ground to absorb negative-going pulses during reverse polarity events. Use Value: Withstands -65 °C to +185 °C operating range and maintains clamping performance after 1000 thermal cycles (−40/+125 °C). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | Same VBR (7.13–7.88 V), but lower PPPM = 400 W; RθJA = 175 °C/W vs. 120–150 °C/W | Limited to lower-energy transients; not qualified to AEC-Q101 | Select SMAJ7.5A only for non-automotive industrial applications where 400 W surge margin suffices and thermal budget allows higher junction rise. |
| TPSMF7.5A | Same SlimSMA package and AEC-Q101 qualification; VC = 12.5 V @ 48.2 A (vs. 11.3 V @ 53.1 A) | Higher clamping voltage reduces protection margin for 5 V logic interfaces | Choose TPSMF7.5A if supply chain prioritizes TI's long-term availability over tighter clamping; verify 12.5 V VC compatibility with downstream IC abs max ratings. |
Compared with SMAJ7.5A and TPSMF7.5A, the TA6F7.5AHM3_A/I offers superior 600 W surge handling, lower clamping voltage, and better thermal resistance - making it optimal for high-reliability automotive signal-line protection where both energy absorption and voltage limiting are critical.
