Product details
Overview
TA6F16AHM3/6B from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and ESD transients on power rails and signal lines. It features a 15.2–16.8 V breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), 600 W peak pulse power (10/1000 μs), 22.5 V maximum clamping voltage at 26.7 A, and AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the TA6F16AHM3/6B datasheet, TA6F16AHM3/6B pinout, TA6F16AHM3/6B application, or TA6F16AHM3/6B equivalent, key selection criteria include unidirectional clamping behavior, DO-221AC (SlimSMA) package compatibility with automated placement, 185 °C junction temperature rating, IEC 61000-4-2 Level 4 ESD immunity, and thermal resistance (RθJA = 145 °C/W) under standard FR-4 mounting.
Technical Context
This TVS diode operates as a voltage-clamping protection device in series with sensitive downstream circuitry, activating above its 13.6 V stand-off threshold to divert surge current away from ICs, MOSFETs, or sensor interfaces. Its passivated anisotropic rectifier structure ensures stable leakage (<1 μA at VWM) and low capacitance across temperature.
The device delivers 600 W peak pulse power handling per 10/1000 μs waveform while maintaining 22.5 V clamping at 26.7 A, enabling robust protection of 12 V automotive systems and industrial control inputs. Its DO-221AC package supports high-density layout and meets MSL Level 1 reflow requirements up to 260 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 15.2 V / 16.8 V - Ensures reliable turn-on above nominal 12 V rail while avoiding false triggering during normal operation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A | Same DO-214AC (SMA) package; 16.7–18.5 V VBR; 600 W PPPM; no AEC-Q101 qualification; RθJA = 160 °C/W | Not qualified for automotive use; higher thermal resistance reduces power handling in compact layouts | Preferred for cost-sensitive industrial or consumer designs where AEC-Q101 and 185 °C operation are not required |
| TPSMD16A | DO-214AB (SMC) package; 16.7–18.5 V VBR; 1500 W PPPM; AEC-Q101 qualified; RθJA = 110 °C/W | Larger footprint (7.11 × 6.22 mm vs. 4.35 × 2.70 mm); higher surge capacity but incompatible with space-constrained layouts | Chosen when higher pulse energy tolerance is needed and board area permits larger SMC package |
Compared with SMAJ16A and TPSMD16A, TA6F16AHM3/6B uniquely balances AEC-Q101 qualification, ultra-low-profile DO-221AC packaging, and 185 °C operation-making it optimal for next-generation automotive ECUs and miniaturized industrial controllers where thermal margin and footprint are simultaneously constrained.

FAQ
What is the breakdown voltage range specified for TA6F16AHM3/6B?
The TA6F16AHM3/6B has a guaranteed breakdown voltage (VBR) range of 15.2 V to 16.8 V at 1.0 mA test current, measured per the Vishay datasheet Document Number 89939. This range ensures consistent clamping onset across production lots and supports design margining for 12 V nominal systems where transient thresholds must exceed steady-state operating voltage without false triggering.
Is TA6F16AHM3/6B suitable for automotive applications?
Yes, TA6F16AHM3/6B is AEC-Q101 qualified and rated for junction temperatures up to 185 °C, making it suitable for under-hood and cabin automotive applications including engine control units, body control modules, and ADAS sensor interfaces. Its DO-221AC package supports automated assembly in high-volume automotive manufacturing lines.
What does the "HM3/6B" suffix indicate in TA6F16AHM3/6B?
The "HM3" suffix denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification and JESD201 Class 2 whisker resistance; "6B" specifies packaging in 13-inch diameter plastic tape and reel containing 14,000 units-optimized for high-speed SMT placement equipment used in automotive and industrial production.
How does the clamping voltage of TA6F16AHM3/6B compare to its stand-off voltage?
TA6F16AHM3/6B has a stand-off voltage (VWM) of 13.6 V and a maximum clamping voltage (VC) of 22.5 V at 26.7 A peak pulse current. This 8.9 V differential provides sufficient headroom to avoid conduction during normal operation while limiting transient overvoltage to a safe level for downstream 24 V-tolerant or 30 V-maximum-rated ICs.
Can TA6F16AHM3/6B be used in bidirectional protection configurations?
No, TA6F16AHM3/6B is unidirectional only, as explicitly stated in the Vishay datasheet. It conducts and clamps only for positive transients relative to its cathode terminal. For bidirectional protection, two TA6F16AHM3/6B devices must be connected in series opposition-or a dedicated bidirectional TVS such as the SMBJ16CA should be selected instead.
