Product details
Overview
TA6F30AHM3/6A from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching transients and ESD events on power/signal lines. It features a breakdown voltage of 28.5–31.5 V at 1 mA, 41.4 V clamping voltage at 14.5 A peak pulse current, 600 W peak pulse power (10/1000 μs), DO-221AC (SlimSMA) package, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TA6F30AHM3/6A datasheet, TA6F30AHM3/6A pinout, TA6F30AHM3/6A application, or TA6F30AHM3/6A equivalent, key selection criteria include unidirectional clamping performance, 185 °C maximum junction temperature, IEC 61000-4-2 Level 4 ESD immunity (15 kV air / 8 kV contact), MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on FR-4 boards.
Technical Context
This TVS diode operates as a unidirectional overvoltage protection device, leveraging passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge stress. Its 185 °C TJ max rating enables operation in high-temperature environments such as engine control units and power converters.
The device exhibits low thermal resistance (RθJM = 20 °C/W) and is characterized for use on minimum recommended pad layout per JESD22-B102, with 0.95 mm typical height enabling ultra-thin PCB designs. It meets UL 94 V-0 flammability and halogen-free RoHS compliance via HM3 suffix construction.

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 DO-214AC package; lower PPPM (400 W); VBR = 33.3–36.8 V; no AEC-Q101 qualification | General-purpose industrial/commercial use only; not rated for automotive under-hood deployment | Select when cost sensitivity outweighs automotive qualification and higher surge margin |
| SMCJ30A | Larger DO-214AB package; higher PPPM (1500 W); same VBR range; AEC-Q101 qualified; 2.2 mm height | Requires more PCB area; suited for higher-energy surge environments (e.g., 48 V battery systems) | Select when >600 W surge handling is required and board space permits larger footprint |
Compared with SMAJ30A and SMCJ30A, TA6F30AHM3/6A uniquely balances ultra-low profile (0.95 mm), AEC-Q101 qualification, and 600 W surge capability in the compact DO-221AC package-making it optimal for space-constrained automotive and industrial modules where thermal headroom and reliability are critical.

FAQ
What is the clamping voltage of TA6F30AHM3/6A at its rated peak pulse current?
The TA6F30AHM3/6A has a maximum clamping voltage (VC) of 41.4 V when subjected to its rated peak pulse current (IPPM) of 14.5 A under the standard 10/1000 μs waveform. This value is measured at TJ = 25 °C and ensures downstream components remain within safe operating voltage limits during transient events.
Is TA6F30AHM3/6A suitable for automotive under-hood applications?
Yes, TA6F30AHM3/6A is AEC-Q101 qualified and rated for a maximum junction temperature of +185 °C, making it suitable for under-hood automotive applications such as engine control units, transmission control modules, and body electronics where ambient temperatures exceed 125 °C.
Does TA6F30AHM3/6A meet RoHS and halogen-free requirements?
Yes, TA6F30AHM3/6A carries the HM3 suffix, confirming it is halogen-free, RoHS-compliant, and manufactured using UL 94 V-0 molding compound - fully aligned with modern environmental and safety standards for electronics manufacturing.
What is the moisture sensitivity level (MSL) rating for TA6F30AHM3/6A?
TA6F30AHM3/6A is rated MSL Level 1 per J-STD-020, with a maximum reflow peak temperature of 260 °C. This eliminates the need for baking prior to assembly and simplifies SMT process integration in high-volume production.
How does the DO-221AC (SlimSMA) package of TA6F30AHM3/6A compare to standard SMA packages?
The DO-221AC (SlimSMA) package of TA6F30AHM3/6A measures just 0.95 mm in height - significantly lower than standard SMA (DO-214AC) packages (~2.3 mm). Its reduced profile enables thinner end products and improves thermal performance due to shorter thermal paths to the PCB copper.
