Product details
Overview
T6N16CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs), designed for automotive-grade ESD and surge protection of sensor signal lines and MOSFET gates.
For engineers reviewing the T6N16CAHM3/H datasheet, T6N16CAHM3/H pinout, T6N16CAHM3/H application, or T6N16CAHM3/H equivalent, key selection criteria include AEC-Q101 qualification, TJ = 185 °C operation, side-wettable DFN package for AOI, clamping voltage of 22.5 V at 26.7 A, and compatibility with SMP (DO-220AA) footprint.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-reliability automotive environments, delivering bidirectional clamping without cathode marking. Its junction passivation enables stable performance under thermal stress up to 185 °C and meets IEC 61000-4-2 ±30 kV contact/air discharge requirements.
The DFN3820A package provides low-profile mounting (0.88 mm height) with matte tin-plated terminals solderable per J-STD-002 and JESD 22-B102, and HM3 suffix confirms halogen-free, RoHS-compliant, AEC-Q101 qualified construction meeting JESD 201 Class 2 whisker resistance.

Applications
| Automotive Sensor Protection | Power Supply Rail Clamping |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive switching transients in engine control units. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed directly at connector interface or IC input pins to shunt surge energy to ground. Use Value: Limits transient voltage to ≤22.5 V during 26.7 A surges, preventing latch-up or gate oxide damage in protected ICs. | Use Scenario: Safeguarding 12 V power rails feeding microcontrollers and driver ICs in ADAS camera modules and radar ECUs. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing ISO 7637-2 Pulse 5a (load dump) energy before it reaches downstream regulators. Use Value: Withstands 600 W peak pulses and operates continuously up to +185 °C, ensuring reliability in high-ambient under-hood environments. |
| MOSFET Gate Protection | Signal Line ESD Suppression |
Use Scenario: Shielding high-side/low-side N-channel MOSFET gates in automotive motor drivers from Miller-induced voltage spikes and ESD. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF typical) TVS placed between gate and source to clamp dv/dt-induced overshoot without slowing switching. Use Value: Clamps gate-source voltage to 22.5 V at 26.7 A, preventing gate oxide rupture while maintaining fast response (<1 ns). | Use Scenario: Hardening LIN bus, PWM dimming, or analog feedback lines in lighting control and HVAC actuators against ESD and cable discharge events. IC Role / Device Role / Timing Role: Bidirectional suppressor installed at PCB entry point to divert ±30 kV IEC 61000-4-2 discharges away from signal conditioning circuitry. Use Value: Delivers 30 kV air/contact ESD immunity without adding series impedance or signal distortion due to symmetric clamping behavior. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA | DO-214AC (SMA) package, 1.9 mm height, higher RθJA (190 °C/W), non-AEC-Q101 rated | Limited to industrial/commercial use; unsuitable for under-hood automotive deployment | Select when cost sensitivity outweighs automotive qualification and space constraints allow larger footprint |
| SMCJ16CA | DO-214AB (SMC) package, 2.3 mm height, 1500 W PPPM, same VBR/VC but lower power density | Better suited for high-energy surge zones (e.g., battery input), not optimized for dense sensor node layouts | Choose where higher surge margin is required and board space permits larger 7.11 mm × 6.22 mm outline |

FAQ
What is the maximum clamping voltage of the T6N16CAHM3/H at its rated peak pulse current?
The T6N16CAHM3/H has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak pulse current (IPPM) of 26.7 A under the standard 10/1000 μs waveform. This value is measured per Figure 3 in the official Vishay datasheet (Document Number: 98489) and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the T6N16CAHM3/H suitable for use in automotive under-hood applications?
Yes, the T6N16CAHM3/H is explicitly qualified to AEC-Q101 and rated for continuous operation up to +185 °C junction temperature, making it suitable for under-hood automotive applications such as engine control units, transmission control modules, and ADAS sensor interfaces where ambient temperatures exceed 125 °C.
Does the T6N16CAHM3/H have polarity markings on its package?
No, the T6N16CAHM3/H is a bidirectional TVS diode and carries no cathode band or polarity marking on the DFN3820A package. Its symmetrical internal structure allows either terminal to be connected to the line or ground side of the protected circuit without functional impact.
What is the standoff voltage (VWM) specification for the T6N16CAHM3/H?
The standoff voltage (VWM) for the T6N16CAHM3/H is 13.6 V, meaning it remains in high-impedance state with ≤1.0 μA reverse leakage current at this DC or RMS voltage level. This ensures compatibility with nominal 12 V automotive systems while providing sufficient margin above normal operating voltage.
How does the DFN3820A package of the T6N16CAHM3/H support automated optical inspection (AOI)?
The DFN3820A package of the T6N16CAHM3/H features side-wettable flanks-exposed copper terminations along the package edges-that reflect light uniformly during AOI. This enables reliable solder joint quality verification without requiring X-ray inspection, reducing manufacturing cost and cycle time in high-volume automotive PCB assembly.
