Product details
Overview
TA6F7.5AHM3/6A from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and ESD transients on power rails and signal lines. It features a 7.13–7.88 V breakdown voltage (VBR), 6.40 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 µs), 11.3 V clamping voltage at 53.1 A peak current, and operates up to 185 °C junction temperature. It is used to protect MOSFET gates and sensor interfaces in automotive body control modules.
For engineers reviewing the TA6F7.5AHM3/6A datasheet, TA6F7.5AHM3/6A pinout, TA6F7.5AHM3/6A application, or TA6F7.5AHM3/6A equivalent, key selection criteria include unidirectional clamping behavior, DO-221AC package compatibility with high-density layouts, AEC-Q101 qualification for automotive use, and thermal resistance (RθJA = 145 °C/W) under standard FR-4 mounting conditions.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for low-leakage, stable clamping under repetitive surge stress. Its 185 °C maximum junction temperature and MSL Level 1 rating support reflow soldering at 260 °C and operation in under-hood automotive environments.
The device delivers 600 W peak pulse power per 10/1000 µs waveform with a clamping ratio (VC/VBR) of ~1.49 and exhibits <250 µA reverse leakage at VWM (6.40 V) and 25 °C - critical for low-power sensor rail protection where standby current must remain minimal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 7.13–7.88 V at 10 mA test current - defines minimum voltage at which clamping initiates reliably |
| Stand-off Voltage VWM | 6.40 V - maximum continuous working voltage before leakage exceeds 250 µA |
| Clamping Voltage VC | 11.3 V at 53.1 A IPPM - limits transient voltage seen by downstream ICs during 10/1000 µs surge |
| Peak Pulse Power PPPM | 600 W (10/1000 µs) - sustains single high-energy transients without failure |
| Junction Temperature Range | –65 °C to +185 °C - enables deployment in engine control units and industrial motor drives |
| ESD Rating | IEC 61000-4-2 Level 4: ±8 kV contact / ±15 kV air - protects against human-body-model discharge events |
| Thermal Resistance RθJA | 145 °C/W - determines self-heating rise above ambient on standard FR-4 PCB pad layout |
Pinout & Package
Package: DO-221AC (SlimSMA), surface-mount, unidirectional configuration with cathode indicated by color band. Dimensions: 5.52 mm × 3.12 mm × 0.95 mm (L × W × H), matte tin-plated terminals, halogen-free and RoHS-compliant (HM3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or lower-potential rail; completes conduction path during reverse-biased surge |
| Cathode | High-side connection point | Marked with color band; connects to protected line (e.g., 5 V supply or CAN_H); conducts when VIN > VBR |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low profile height | 0.95 mm typical - enables placement beneath low-clearance shields and in compact automotive ECUs |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress - required for ASIL-B systems |
| Junction passivation design | Reduces long-term parameter drift under thermal-humidity bias - ensures stable VBR over 15-year vehicle lifetime |
| MSL Level 1 rating | Supports single-reflow assembly at 260 °C peak without popcorn or delamination - eliminates pre-bake requirements |
| Uni-directional clamping only | Prevents unintended conduction during normal forward-biased operation - avoids loading of DC power rails |
Applications
| Automotive Body Control Module (BCM) | Industrial Sensor Interface Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A | Higher VBR (6.67–7.37 V), same DO-214AC package, 600 W rating, but only rated to 150 °C TJ max | Lacks AEC-Q101 qualification and 185 °C capability - unsuitable for under-hood automotive use | Select SMAJ7.0A only for cost-sensitive industrial applications where extended temperature range is not required |
| TPSMF7.0A | Same VBR range (6.67–7.37 V), DO-214AC, 600 W, AEC-Q101 qualified, but 175 °C TJ max (vs. 185 °C) | Lower thermal margin may require derating in high-ambient environments (>125 °C board temp) | Acceptable for cabin-mounted automotive modules but verify thermal margin using RθJA = 150 °C/W |
Compared with SMAJ7.0A and TPSMF7.0A, TA6F7.5AHM3/6A provides superior high-temperature robustness (185 °C vs. 150/175 °C), tighter VBR tolerance (±5% vs. ±6.5%), and lower clamping voltage (11.3 V vs. ≥11.5 V), making it preferred for mission-critical automotive power rail protection.

FAQ
What is the exact breakdown voltage range for TA6F7.5AHM3/6A?
The TA6F7.5AHM3/6A has a guaranteed breakdown voltage (VBR) range of 7.13 V to 7.88 V at 10 mA test current, measured per JEDEC JESD22-A114. This tight ±5% tolerance ensures predictable clamping onset across production lots and temperature extremes, critical for protecting sensitive 5 V or 3.3 V logic rails without premature conduction.
Is TA6F7.5AHM3/6A suitable for automotive under-hood applications?
Yes, TA6F7.5AHM3/6A is AEC-Q101 qualified and rated for continuous operation up to +185 °C junction temperature - exceeding standard automotive under-hood requirements (typically 150 °C). Its DO-221AC package passes MSL Level 1 reflow and maintains stable VBR and leakage performance after thermal cycling, making it appropriate for engine control units and transmission control modules.
What is the clamping voltage of TA6F7.5AHM3/6A at its rated peak pulse current?
The TA6F7.5AHM3/6A clamps to a maximum of 11.3 V at its specified peak pulse current (IPPM) of 53.1 A, tested with a 10/1000 µs waveform. This clamping voltage is measured at the device terminals under standardized conditions and defines the upper voltage limit imposed on protected circuitry during surge events - essential for ensuring downstream ICs remain within absolute maximum ratings.
Does TA6F7.5AHM3/6A support automated SMT placement?
Yes, TA6F7.5AHM3/6A is optimized for automated surface-mount placement with its DO-221AC (SlimSMA) package: 0.95 mm profile, matte tin-plated leads compliant with J-STD-002 and JESD22-B102, and HM3 suffix meeting JESD201 Class 2 whisker resistance. Its symmetrical geometry and defined cathode band enable reliable vision-based alignment and high-yield reflow on standard 7" tape-and-reel feeders.
How does the thermal resistance of TA6F7.5AHM3/6A affect PCB layout?
TA6F7.5AHM3/6A has a typical junction-to-ambient thermal resistance (RθJA) of 145 °C/W on standard FR-4 with minimum recommended pad layout. To avoid exceeding 185 °C junction temperature at 6 W steady-state dissipation, designers must ensure adequate copper area (≥40 mm² per side) and consider thermal vias - especially in enclosed enclosures where ambient exceeds 85 °C.
