Product details
Overview
TA6L30AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SlimSMAW (DO-221AD) package, designed for automotive-grade overvoltage protection. It features a 30 V nominal breakdown voltage (VBR), 25.6 V maximum standoff voltage (VWM), 41.4 V clamping voltage at 14.5 A peak pulse current, 600 W peak pulse power (10/1000 µs), and 185 °C maximum junction temperature - enabling robust protection of MOSFETs, sensor signal lines, and ICs against inductive switching transients.
For engineers reviewing the TA6L30AHM3/H datasheet, TA6L30AHM3/H pinout, TA6L30AHM3/H application, or TA6L30AHM3/H equivalent, key selection considerations include its AEC-Q101 qualification, unidirectional polarity, SlimSMAW thermal performance (RθJM = 12–15 °C/W), and compatibility with high-reliability automotive electronics requiring TJ = 185 °C operation and JESD201 Class 2 whisker resistance.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for junction stability under high-temperature stress. Its unidirectional configuration provides low-leakage reverse blocking up to 25.6 V while delivering precise clamping at 41.4 V under 14.5 A surge current (10/1000 µs waveform).
The device operates across -65 °C to +185 °C junction temperature range and meets MSL Level 1 reflow requirements (260 °C peak). Its SlimSMAW (DO-221AD) package enables high power density with low thermal resistance (RθJM ≤ 15 °C/W) and halogen-free, RoHS-compliant construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 28.5 / 30.0 / 31.5 V - ensures reliable conduction onset above system operating voltage with tight tolerance for predictable clamping threshold |
| VWM | 25.6 V - maximum continuous reverse voltage before leakage exceeds 1 μA, compatible with 24 V automotive supply rails |
| VC @ IPPM | 41.4 V - clamping voltage at 14.5 A peak pulse, limiting protected circuit voltage during 600 W transient events |
| PPPM | 600 W (10/1000 µs) - sustains high-energy surges common in automotive load-dump and inductive-switching scenarios |
| TJ max | +185 °C - supports under-hood deployment and long-term reliability in high-temperature automotive environments |
| Package | SlimSMAW (DO-221AD) - low-profile surface-mount outline with 0.118" max height, optimized for thermal transfer to PCB copper |
| AEC-Q101 | Qualified - validated for automotive electronic systems per stress test requirements including temperature cycling and HTRB |
Pinout & Package
SlimSMAW (DO-221AD) package: cathode-indicating band on top surface; anode and cathode terminals formed as flat, matte tin-plated leads suitable for J-STD-002 soldering. Mounting pad layout follows JEDEC DO-221AD standard with 0.055" minimum pad length and 0.075" pad width.

|---|---|
Use Scenario: Protecting analog output signals from wheel speed sensors, pressure transducers, and position encoders exposed to load-dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output line and ground to clamp transients before they reach downstream ADC or microcontroller input. Use Value: Prevents latch-up or damage to precision analog front-ends by limiting voltage to ≤41.4 V during 14.5 A surges, maintaining signal integrity in ASIL-B systems. |
Use Scenario: Safeguarding 24 V supply inputs to ECUs, body control modules, and lighting drivers against battery reversal and alternator load dump. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing energy from ISO 7637-2 Pulse 5a (load dump) events up to 600 W. Use Value: Maintains system uptime by preventing overvoltage shutdown or MOSFET gate oxide rupture during 35 V/400 ms transients. |
| MOSFET Gate Protection | Infotainment Signal Line Guarding |
Use Scenario: Shielding high-side and low-side N-channel MOSFET gates in motor drivers and solenoid controllers from ESD and inductive spikes. IC Role / Device Role / Timing Role: Low-capacitance TVS placed directly at gate-to-source to suppress sub-100 ns transients before gate oxide breakdown occurs. Use Value: Limits gate-source voltage to ≤41.4 V during fast-rising spikes, avoiding irreversible gate oxide failure while preserving switching timing fidelity. |
Use Scenario: Securing LIN bus, CAN FD stub lines, and audio differential pairs in head units and telematics modules against ESD and board-level coupling. IC Role / Device Role / Timing Role: Unidirectional TVS on each signal line referenced to chassis ground, leveraging low leakage (<1 μA at 25.6 V) to avoid signal distortion. Use Value: Ensures EMC compliance (IEC 61000-4-2 Level 4) without degrading signal rise time due to minimal junction capacitance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | Same VWM (25.6 V), identical SlimSMA package, but rated for 400 W PPPM and not AEC-Q101 qualified | Limited to industrial or consumer applications lacking automotive qualification requirements | Select SMAJ30A only if AEC-Q101 is not mandated and 400 W surge capacity suffices for system-level testing. |
| TPSMD30A | Same 30 V VBR, 600 W rating, and AEC-Q101 qualification, but uses larger SMA (DO-214AC) package with higher RθJA (160 °C/W) | Acceptable for less thermally constrained layouts; lower power density than SlimSMAW | Choose TPSMD30A when existing PCB footprint accommodates SMA and thermal margin allows higher junction rise. |
Compared with SMAJ30A and TPSMD30A, TA6L30AHM3/H delivers superior thermal performance in automotive space-constrained designs due to its SlimSMAW package (RθJM ≤ 15 °C/W) and full AEC-Q101 validation - making it optimal for next-generation ADAS and electrified powertrain modules where reliability and miniaturization intersect.

FAQ
What is the maximum clamping voltage of the TA6L30AHM3/H under standard test conditions?
The TA6L30AHM3/H has a maximum clamping voltage (VC) of 41.4 V when subjected to its rated peak pulse current of 14.5 A using the 10/1000 µs waveform. This value is measured per IEC 61000-4-5 and ANSI/IEEE C62.35 standards and ensures protected circuits remain below critical overvoltage thresholds during surge events. The TA6L30AHM3/H maintains this clamping performance across its full operating temperature range.
Is the TA6L30AHM3/H qualified for automotive applications?
Yes, the TA6L30AHM3/H is AEC-Q101 qualified and meets JESD201 Class 2 whisker test requirements. Its 185 °C maximum junction temperature, MSL Level 1 reflow compatibility, and halogen-free, RoHS-compliant construction make it suitable for under-hood and safety-critical automotive systems including engine control, ADAS sensors, and body electronics. The HM3 suffix explicitly denotes this qualification.
What package type does the TA6L30AHM3/H use, and how does it differ from standard SMA?
The TA6L30AHM3/H uses the SlimSMAW (DO-221AD) package - a low-profile variant of SMA with reduced height (max 0.118") and optimized thermal pad geometry. Unlike standard SMA (DO-214AC), SlimSMAW achieves lower junction-to-mount thermal resistance (RθJM ≤ 15 °C/W), enabling higher power handling in compact automotive layouts. Its footprint remains compatible with automated SMT placement equipment.
Does the TA6L30AHM3/H support bidirectional transient suppression?
No, the TA6L30AHM3/H is a unidirectional TVS diode, intended for DC-biased lines such as 24 V power rails, sensor outputs, and MOSFET gate drives. It conducts only when the cathode voltage exceeds the anode by ≥28.5 V. For AC or bipolar signal lines, a separate bidirectional variant (e.g., TA6L30AHE3) would be required - the TA6L30AHM3/H is not rated for reverse conduction.
What is the leakage current specification for the TA6L30AHM3/H at its maximum standoff voltage?
At its maximum standoff voltage (VWM) of 25.6 V and ambient temperature of 25 °C, the TA6L30AHM3/H exhibits a maximum reverse leakage current (IR) of 1.0 μA. At elevated junction temperatures up to 150 °C, leakage increases to no more than 5.0 μA - ensuring minimal power loss and signal interference in always-on automotive subsystems.
