Product details
Overview
TA6F36AHM3/6B from Vishay General Semiconductor is a unidirectional surface-mount PAR® Transient Voltage Suppressor (TVS) designed for clamping inductive switching transients and ESD events on signal lines and power rails. It features a breakdown voltage of 34.2–37.8 V at 1 mA, clamps to ≤49.9 V at 12.0 A (10/1000 μs), delivers 600 W peak pulse power, operates up to +185 °C junction temperature, and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the TA6F36AHM3/6B datasheet, TA6F36AHM3/6B pinout, TA6F36AHM3/6B application, or TA6F36AHM3/6B equivalent, key selection criteria include unidirectional clamping behavior, DO-221AC (SlimSMA) package compatibility with automated placement, 1.0 μA max reverse leakage at 30.8 V, MSL Level 1 moisture sensitivity, and IEC 61000-4-2 Level 4 ESD robustness (±8 kV contact / ±15 kV air).
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for high-temperature stability and low-profile mounting. Its unidirectional architecture enables precise forward-biased conduction during overvoltage events while maintaining tight stand-off voltage control (30.8 V) and low dynamic impedance under surge conditions.
The device is rated for 600 W peak pulse power (10/1000 μs), supports continuous power dissipation of 6 W at 65 °C on infinite heat sink, and exhibits thermal resistance of 20 °C/W junction-to-mount - critical for PCB-level thermal management in compact automotive and industrial modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 34.2–37.8 V at 1 mA - defines minimum clamping initiation threshold under controlled DC test |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36A | Same DO-214AC package; higher RθJA (150 °C/W vs. 145 °C/W); VBR = 40–44.4 V; lower PPPM = 400 W | Limited to lower-energy transients; less suitable for automotive load dump where 600 W margin is required | Select TA6F36AHM3/6B when 600 W rating, AEC-Q101 qualification, or 185 °C TJ are mandatory |
| SMCJ36A | DO-214AB package (larger footprint); same VBR range; PPPM = 1500 W; RθJA = 12 °C/W junction-to-mount | Requires more PCB area; better for high-power industrial surge but incompatible with SlimSMA layout | Choose TA6F36AHM3/6B for space-constrained designs needing AEC-Q101 and minimal height |
Compared with SMAJ36A and SMCJ36A, TA6F36AHM3/6B uniquely combines 600 W pulse power, DO-221AC ultra-low profile (0.95 mm), AEC-Q101 qualification, and 185 °C junction rating - making it optimal for next-generation automotive ECUs and miniaturized industrial sensors where thermal, spatial, and reliability constraints converge.

FAQ
What is the exact breakdown voltage range for TA6F36AHM3/6B?
The TA6F36AHM3/6B has a guaranteed breakdown voltage (VBR) range of 34.2 V to 37.8 V at a test current of 1.0 mA, measured per the Vishay datasheet Document Number 89939. This range ensures consistent clamping behavior across production lots and supports design margining for 36 V nominal systems.
Is TA6F36AHM3/6B suitable for automotive under-hood applications?
Yes, TA6F36AHM3/6B is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood automotive applications such as engine control units, battery disconnect units, and transmission control modules where ambient temperatures exceed 125 °C.
Does TA6F36AHM3/6B have bidirectional capability?
No, TA6F36AHM3/6B is unidirectional only. Its electrical characteristics - including specified VBR, VWM, and clamping behavior - apply only in reverse-bias mode. For bidirectional protection, two TA6F36AHM3/6B devices must be used in series opposition or a dedicated bidirectional TVS selected.
What is the moisture sensitivity level (MSL) of TA6F36AHM3/6B?
TA6F36AHM3/6B meets MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30 °C/60% RH and requires no baking prior to reflow soldering - simplifying manufacturing flow and reducing process risk in high-volume SMT lines.
How does the DO-221AC package of TA6F36AHM3/6B compare to standard SMA packages?
The DO-221AC (SlimSMA) package of TA6F36AHM3/6B measures 0.163–0.171 inches in length and just 0.039–0.049 inches in height (0.95 mm typical), offering ~30% lower profile than standard DO-214AC (SMA). This enables thinner end products and improved airflow in stacked PCB assemblies.
