Product details
Overview
TA6F36AHM3_A/I 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), and 185 °C maximum junction temperature - designed for automotive-grade ESD and surge protection of sensor signal lines and MOSFET gates.
For engineers reviewing the TA6F36AHM3_A/I datasheet, TA6F36AHM3_A/I pinout, TA6F36AHM3_A/I application, or TA6F36AHM3_A/I equivalent, this device delivers AEC-Q101 qualification, 30 kV IEC 61000-4-2 ESD immunity, MSL Level 1 moisture sensitivity, and low-profile 0.95 mm height for high-density automated placement in harsh-environment electronics.
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) and tight VBR tolerance (±5% typical). Its thermal resistance RθJA is 120–150 °C/W on FR4 PCB with minimum recommended pad layout, enabling reliable operation up to TJ = 185 °C.
The device operates unidirectionally with cathode band marking, exhibits 0.090 %/°C temperature coefficient of VBR, and delivers 12.0 V clamping voltage (VC) at 49.9 A peak pulse current (IPPM) - optimized for fast response to inductive switching spikes and lightning-induced surges in automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 34.2 / 36.0 / 37.8 V - ensures precise overvoltage triggering above system operating rail (30.8 V VWM) without false trips |
| VC @ IPPM | 12.0 V at 49.9 A - limits downstream IC voltage stress during 600 W transient events |
| IPPM (10/1000 μs) | 49.9 A - supports robust surge handling per ISO 7637-2 Pulse 1/2a/5a in automotive ECUs |
| TJ max | 185 °C - enables deployment in engine bay, transmission control, and ADAS modules without derating |
| ESD rating | 30 kV contact/air per IEC 61000-4-2 - protects against human-body-model and system-level ESD events |
| Package | SlimSMA (DO-221AC), 0.95 mm height - fits ultra-thin layouts and passes automated optical inspection (AOI) |
| MSL level | Level 1 per J-STD-020 - allows unlimited floor life and reflow at 260 °C peak without baking |
Pinout & Package

Applications
| Automotive Sensor Protection | Power MOSFET Gate Clamp |
|---|---|
|
Use Scenario: Protecting LIN/CAN bus sensor nodes (e.g., wheel speed, pressure, temperature) from load-dump and inductive kickback in 12 V systems. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output line and ground to clamp transients before they reach analog front-end or microcontroller input. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V interface ICs during 100 V/500 ms load dump events per ISO 16750-2. |
Use Scenario: Safeguarding gate oxide of N-channel power MOSFETs used in automotive DC-DC converters and motor drivers. IC Role / Device Role / Timing Role: TVS connected between gate and source to limit VGS excursion during fast-switching dv/dt events or Miller-induced spikes. Use Value: Maintains gate voltage within ±20 V absolute maximum rating, avoiding irreversible gate rupture during 100 ns rise-time transients. |
| ADAS Camera Power Line | Infotainment USB Data Line |
|
Use Scenario: Securing 5 V power rail feeding CMOS image sensors and ISP processors in forward-facing ADAS cameras exposed to engine compartment heat. IC Role / Device Role / Timing Role: TVS installed at camera module input to absorb ISO 7637-2 Pulse 5b (100 V, 0.5 Ω) surges induced by alternator regulation faults. Use Value: Clamps voltage to ≤12.0 V within 1 ns, preserving sensor functionality and preventing black-frame artifacts during transient exposure. |
Use Scenario: Shielding USB 2.0 D+/D− lines in head-unit infotainment systems from ESD events during user insertion/removal of peripherals. IC Role / Device Role / Timing Role: Dual-channel TVS array not applicable here; TA6F36AHM3_A/I serves as single-line protector on VBUS or individual data line where unidirectional clamping suffices. Use Value: Withstands 30 kV contact discharge without parametric shift, ensuring USB enumeration reliability after repeated hot-plug cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A | Same VBR (36.0 V), but SMA package (1.6 mm height); RθJA = 160 °C/W; no AEC-Q101 qualification | Limited to industrial/commercial environments; unsuitable for under-hood automotive deployments | Select SMAJ36A only if board height > 1.0 mm is acceptable and automotive qualification is not required. |
| TPSMF36A | DO-214AB (SMC) package; higher IPPM (64.5 A); same VC (12.0 V); AEC-Q101 qualified; 2.3 mm height | Better suited for high-energy surges (e.g., alternator load dump) but requires more PCB area and height | Choose TPSMF36A when surge energy exceeds 600 W or when legacy SMC footprint compatibility is mandatory. |
Compared with SMAJ36A and TPSMF36A, TA6F36AHM3_A/I uniquely balances AEC-Q101 compliance, ultra-low 0.95 mm profile, and verified 185 °C operation - making it optimal for next-gen compact automotive modules where thermal margin and space constraints dominate selection.

FAQ
What is the breakdown voltage tolerance of TA6F36AHM3_A/I?
The TA6F36AHM3_A/I has a specified breakdown voltage range of 34.2 V (min) to 37.8 V (max) at 1.0 mA test current, yielding a ±5% tolerance around the nominal 36.0 V value. This tight distribution ensures consistent clamping behavior across production lots and supports robust design margins in automotive signal protection circuits.
Is TA6F36AHM3_A/I suitable for bidirectional transient suppression?
No, TA6F36AHM3_A/I is a unidirectional TVS diode, intended for clamping positive-going transients on grounded-return circuits. It must be oriented with cathode toward the protected line. For bidirectional protection (e.g., AC lines or differential buses), a separate bidirectional device such as the SMBJ36CA would be required - TA6F36AHM3_A/I does not support reverse-polarity surge suppression.
Does TA6F36AHM3_A/I require derating at elevated ambient temperatures?
Yes, TA6F36AHM3_A/I power dissipation must be derated above 25 °C ambient per Figure 5 in Vishay Doc. #89939. At 65 °C case temperature, its continuous power rating drops to 8 W; at 100 °C, it falls to approximately 4.5 W. Designers must apply thermal modeling using RθJA = 120–150 °C/W and verify junction temperature stays ≤185 °C under worst-case surge duty cycles.
What is the meaning of the "HM3_A/I" suffix in TA6F36AHM3_A/I?
The "HM3" denotes the SlimSMA (DO-221AC) package variant; "A" indicates the revision code per Vishay's base P/NHM3_X convention; "I" specifies the packaging format - 13-inch tape-and-reel with 14,000 units per reel. The "/I" suffix directly maps to delivery mode and quantity, not electrical or thermal characteristics.
Can TA6F36AHM3_A/I replace SMAJ36A in an existing design without layout changes?
No - although both share identical VBR and VC specs, TA6F36AHM3_A/I uses SlimSMA (DO-221AC) footprint, which differs mechanically from SMA. Pad dimensions, terminal spacing, and solder mask openings are incompatible. A redesign of the land pattern and stencil is required to migrate from SMAJ36A to TA6F36AHM3_A/I.
