Overview
TA6L30AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor in SlimSMAW (DO-221AD) package, rated for 30 V breakdown voltage (VBR = 28.5–31.5 V at 1 mA), 25.6 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 µs). It delivers 14.5 A peak pulse current (IPPM) with 41.4 V clamping voltage (VC) and operates up to +185 °C junction temperature - designed for automotive-grade overvoltage protection of MOSFETs and sensor signal lines.
For engineers reviewing the TA6L30AHM3/I datasheet, TA6L30AHM3/I pinout, TA6L30AHM3/I application, or TA6L30AHM3/I equivalent, this page provides verified electrical specs, thermal derating behavior, AEC-Q101 qualification status, SlimSMAW mechanical dimensions, and direct alternatives with documented clamping and leakage differences.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for high-temperature stability and low-leakage performance. Its unidirectional configuration enables precise reverse-biased clamping during positive transients, with junction passivation ensuring reliability under automotive thermal cycling (TJ = −65 °C to +185 °C).
The device meets MSL Level 1 per J-STD-020, supports 260 °C lead-free reflow, and features matte tin-plated leads solderable per J-STD-002. Its SlimSMAW (DO-221AD) package offers low profile and UL 94 V-0 flammability compliance, with cathode indicated by color band.
Key Specifications

IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp surges >40 V. Use Value: With 41.4 V clamping and 14.5 A IPPM, TA6L30AHM3/I limits voltage seen by downstream PMICs and microcontrollers to safe levels during 100 V/100 ms events. |
Use Scenario: Safeguarding analog inputs of pressure, temperature, and position sensors connected to ECU via long harnesses. IC Role / Device Role / Timing Role: TVS mounted at connector entry point to absorb coupled inductive spikes from nearby solenoids or relays. Use Value: Sub-1 µA leakage at 25.6 V VWM prevents DC offset errors in precision ratiometric sensor bridges; 185 °C rating ensures reliability in engine bay mounting. |
| Body Control Module (BCM) LIN Bus | Electric Power Steering (EPS) Motor Driver |
Use Scenario: Protecting LIN transceiver pins (e.g., TJA1020) from ESD and cable discharge events in door modules and lighting nodes. IC Role / Device Role / Timing Role: Low-capacitance unidirectional TVS placed directly at transceiver I/O pins to suppress fast transients without signal distortion. Use Value: SlimSMAW footprint minimizes board space; 1.0 µA leakage preserves LIN bus idle-state voltage integrity and avoids false wake-up. |
Use Scenario: Clamping voltage spikes induced by PWM-driven 3-phase motor windings in EPS actuator control units. IC Role / Device Role / Timing Role: TVS installed across high-side MOSFET source-drain or gate drive lines to prevent avalanche-induced latch-up. Use Value: 600 W peak pulse power rating handles repetitive 10/1000 µs surges common in motor commutation; AEC-Q101 qualification validates endurance over 10,000 cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | VBR = 33.3–36.8 V; VC = 48.4 V at 12.4 A; RθJA = 150 °C/W; not AEC-Q101 qualified | Higher clamping voltage reduces margin for 3.3 V or 5 V logic; lacks automotive qualification | Select SMAJ30A only for cost-sensitive industrial applications where AEC-Q101 and 185 °C operation are not required. |
| TPSMF30A | VBR = 31.7–35.1 V; VC = 48.4 V at 12.4 A; TJ max = +150 °C; AEC-Q101 qualified but no JESD201 Class 2 whisker test | Lower thermal capability limits placement near high-power stages; same clamping as SMAJ30A | Choose TPSMF30A when AEC-Q101 is mandatory but 185 °C operation is unnecessary - e.g., cabin electronics with ambient <125 °C. |
Compared with SMAJ30A and TPSMF30A, TA6L30AHM3/I provides tighter VBR tolerance (±5 % vs. ±10 %), lower clamping (41.4 V vs. ≥48.4 V), and superior thermal resilience (185 °C vs. ≤150 °C), making it the only option qualified for under-hood powertrain and steering systems requiring JESD201 Class 2 whisker resistance.

FAQ
What is the exact breakdown voltage range for TA6L30AHM3/I?
The TA6L30AHM3/I has a guaranteed breakdown voltage (VBR) range of 28.5 V to 31.5 V at test current IT = 1.0 mA, per Vishay Document Number 87415. This ±5 % tolerance ensures predictable clamping onset across production lots and temperature extremes, supporting deterministic design margins in 24 V automotive systems where TA6L30AHM3/I is commonly deployed.
Is TA6L30AHM3/I qualified for automotive use?
Yes, TA6L30AHM3/I is AEC-Q101 qualified and its HM3 suffix confirms compliance with JESD22-A114 (HTOL), JESD22-A108 (TC), and JESD201 Class 2 whisker testing. The device is rated for operation up to +185 °C junction temperature and meets MSL Level 1 - all requirements for front-end power and sensor protection in modern automotive ECUs, making TA6L30AHM3/I suitable for safety-critical vehicle subsystems.
What does the "HM3" suffix indicate in TA6L30AHM3/I?
The "HM3" suffix in TA6L30AHM3/I denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance. It also specifies packaging in 13″ tape-and-reel (14,000 units per reel), distinguishing it from the "H" variant (7″ reel, 3,500 units). The HM3 marking appears as the device code "BRL" on the top surface of the SlimSMAW package.
How does TA6L30AHM3/I compare to standard SMAJ30A in clamping performance?
TA6L30AHM3/I clamps at 41.4 V (at 14.5 A), while SMAJ30A clamps at 48.4 V (at 12.4 A). This 7 V lower clamping voltage gives TA6L30AHM3/I significantly more margin for protecting 3.3 V or 5 V logic interfaces downstream. Additionally, TA6L30AHM3/I's tighter VBR tolerance and 185 °C rating make it unsuitable for direct substitution with SMAJ30A in automotive designs requiring AEC-Q101 compliance.
What is the thermal resistance of TA6L30AHM3/I and how does it affect layout?
TA6L30AHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W on standard FR4 with 2 oz. copper, per JEDEC 51-2A. For repetitive surge conditions, thermal design must account for this value: a 1 W average dissipation raises junction temperature by ~120 °C above ambient. Layout best practices include using thermal vias under the cathode/anode pads and minimizing trace length to reduce inductance during fast transients - both validated in TA6L30AHM3/I reference layouts.
