Product details
Overview
TA6L7.5AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) in SlimSMAW (DO-221AD) package, designed for automotive-grade overvoltage protection of signal lines and MOSFET gates. It features 7.5 V nominal breakdown voltage (VBR), 6.4 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), 11.3 V maximum clamping voltage at rated surge current, and AEC-Q101 qualification with TJ = 185 °C capability.
For engineers reviewing the TA6L7.5AHM3/I datasheet, TA6L7.5AHM3/I pinout, TA6L7.5AHM3/I application, or TA6L7.5AHM3/I equivalent, this page delivers verified electrical parameters, SlimSMAW package dimensions, automotive-grade reliability data, and direct alternatives for ESD/surge protection in sensor interfaces, power supply rails, and CAN/LIN bus line protection.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping performance across -65 °C to +185 °C junction temperature range. Its unidirectional configuration enables precise reverse-biased protection of DC-coupled circuits without forward conduction interference.
The device meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility and incorporates halogen-free, RoHS-compliant molding compound rated UL 94 V-0. Cathode identification via color band ensures correct PCB orientation during automated assembly.

Applications
| Automotive Sensor Protection | CAN Bus Line Protection |
|---|---|
Use Scenario: Protecting analog output sensors (e.g., pressure, temperature) from load-dump and inductive switching transients in 12 V vehicle networks. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor signal line and chassis ground to clamp fast-rising transients before they reach ADC input or signal conditioner. Use Value: Prevents sensor output corruption and microcontroller reset events caused by >100 V transients, leveraging 11.3 V clamping and 53.1 A surge rating. |
Use Scenario: Safeguarding CANH/CANL differential pair against ESD and coupled surges in body control modules and gateway ECUs. IC Role / Device Role / Timing Role: Dual-device implementation (one per line) providing bidirectional protection using two unidirectional TA6L7.5AHM3/I diodes back-to-back. Use Value: Maintains CAN signal integrity below 1 Mbps with <1 pF junction capacitance and withstands ±25 kV contact ESD per IEC 61000-4-2. |
| Power Supply Rail Clamp | Industrial Motor Drive Gate Protection |
Use Scenario: Secondary overvoltage clamp on 5 V or 3.3 V regulator outputs feeding safety-critical MCU peripherals. IC Role / Device Role / Timing Role: Standby protection element that activates only during fault conditions, minimizing leakage (<250 μA at VWM) during normal operation. Use Value: Limits rail excursion to ≤11.3 V during 100 ns–1 μs transients, preventing latch-up or permanent damage to downstream logic. |
Use Scenario: Gate-source protection of N-channel MOSFETs in half-bridge motor drivers exposed to Miller-induced voltage spikes. IC Role / Device Role / Timing Role: Fast-response clamp connected between gate and source to absorb dv/dt-induced overshoot before it exceeds VGS(max). Use Value: Responds within nanoseconds to limit gate stress to 11.3 V, preserving MOSFET reliability under PWM switching with high-side/lower-side cross-talk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Higher VBR (6.65–7.37 V), same 600 W rating, SMB (DO-214AA) package with larger footprint (4.57 mm × 3.94 mm). | Less suitable for ultra-compact automotive modules due to 40% larger board area; lower thermal resistance (RθJA ≈ 100 °C/W) allows higher average power dissipation. | Select SMBJ7.0A when layout space permits and higher steady-state thermal margin is required over peak transient handling. |
| TPSMF7.0A | Same VBR range (6.65–7.37 V), 600 W rating, SOD-128 (DO-221AD) package identical to SlimSMAW but with non-AEC-Q101 qualification and 175 °C TJ max. | Lacks automotive qualification and high-temperature endurance; appropriate for industrial or consumer applications where AEC-Q101 is not mandated. | Choose TPSMF7.0A for cost-sensitive non-automotive designs requiring identical form factor and clamping performance without automotive validation overhead. |
Compared with TA6L7.5AHM3/I, SMBJ7.0A trades compactness for thermal headroom, while TPSMF7.0A matches mechanical fit and clamping but omits AEC-Q101 and 185 °C operation-making TA6L7.5AHM3/I the sole choice for under-hood automotive deployments demanding full qualification and extended temperature resilience.

Does TA6L7.5AHM3/I have automotive qualification?
Yes, TA6L7.5AHM3/I carries the HM3 suffix indicating AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It is validated for automotive use with guaranteed operation from -65 °C to +185 °C junction temperature and tested per stress requirements including HTOL, TCT, and HTRB.
What is the maximum clamping voltage of TA6L7.5AHM3/I at rated surge current?
The TA6L7.5AHM3/I exhibits a maximum clamping voltage (VC) of 11.3 V at its rated peak pulse current (IPPM) of 53.1 A under the 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
How does the SlimSMAW package of TA6L7.5AHM3/I compare to standard SMA?
The SlimSMAW (DO-221AD) package of TA6L7.5AHM3/I measures 2.70 mm × 4.00 mm with 1.10 mm height-approximately 30% smaller in footprint and 40% lower in profile than standard SMA (DO-214AC). Its exposed copper pads enhance thermal transfer, achieving RθJM of 12–15 °C/W despite reduced size.
