Product details
Overview
T6N16AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor in DFN3820A package, rated for 16.0 V nominal breakdown voltage (VBR), 13.6 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs). It delivers 26.7 A peak pulse current and clamps to 22.5 V at IPPM, with AEC-Q101 qualification and 185 °C maximum junction temperature - deployed for automotive sensor line protection against load dump and ESD.
For engineers reviewing the T6N16AHM3/H datasheet, T6N16AHM3/H pinout, T6N16AHM3/H application, or T6N16AHM3/H equivalent, key selection criteria include unidirectional clamping behavior, DFN3820A side-wettable flanks for AOI, TJ = 185 °C capability, MSL Level 1 rating, and compatibility with SMP (DO-220AA) footprint - all critical for high-reliability automotive PCB designs.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with junction passivation optimized for stable clamping under repetitive surge stress. Its unidirectional configuration enables precise reverse-biased overvoltage protection on signal or power rails where polarity is fixed.
The DFN3820A package provides low thermal resistance (RθJM = 5 °C/W typical) and supports automated placement with matte tin-plated terminals solderable per J-STD-002. Polarity is marked by cathode band; heatsink pad serves as anode terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |

|---|---|
Use Scenario: Protecting LIN/CAN transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from inductive switching spikes and ESD in engine control units. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp transients before reaching precision analog front-end or digital receiver. Use Value: Maintains signal integrity below 22.5 V clamping threshold while surviving 26.7 A surges - preventing latch-up or damage to 3.3 V/5 V interface ICs. |
Use Scenario: Safeguarding 5 V/12 V power rails feeding audio amplifiers, display drivers, and USB controllers in head units and telematics modules. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing load-dump energy (ISO 16750-2) and suppressing conducted noise from alternator ripple. Use Value: 600 W peak power rating handles 12 V system surges up to 35 V for 40 ms without derating - ensuring uninterrupted operation during battery disconnect events. |
| ADAS Camera Module ESD Shielding | Body Control Module (BCM) Signal Line Protection |
Use Scenario: Front-end protection of MIPI CSI-2 differential pairs and power supplies in surround-view camera modules exposed to 30 kV ESD per IEC 61000-4-2.

Use Value: Side-wettable DFN3820A allows full AOI coverage of solder joints - critical for zero-defect manufacturing in safety-critical vision systems. |
Use Scenario: Overvoltage suppression on wake-up lines, door lock actuator drivers, and ambient light sensor inputs within BCMs subjected to battery reversal and jump-start conditions. IC Role / Device Role / Timing Role: Unidirectional clamping device referenced to vehicle ground, protecting microcontroller GPIOs and discrete driver transistors. Use Value: 185 °C junction rating ensures functional stability during prolonged under-dash thermal exposure - eliminating need for derating in high-ambient designs. |
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 | DO-214AC (SMA) package, higher RθJA (≈200 °C/W), 150 °C TJ max, non-AEC-Q101 | Limited to industrial or consumer use; not qualified for automotive under-hood deployment | Select when cost-sensitive non-automotive designs require legacy SMA footprint compatibility |
| SMF16A | SOD-123FL package, 150 °C TJ max, 400 W PPPM, no side-wettable flanks | Lower surge rating and no AOI support - unsuitable for high-volume automotive SMT lines requiring full process traceability | Choose only for space-constrained consumer boards where AEC-Q101 and AOI are not required |
Compared with SMAJ16A and SMF16A, T6N16AHM3/H uniquely combines AEC-Q101 qualification, 185 °C operation, side-wettable DFN3820A for AOI, and 600 W surge capability - making it the only option qualified for zero-defect automotive electronics production with full process visibility.

FAQ
What is the breakdown voltage tolerance for T6N16AHM3/H?
The T6N16AHM3/H has a ±5 % breakdown voltage tolerance, specified as 15.2 V (min) to 16.8 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margining in 12 V automotive systems where the T6N16AHM3/H is commonly applied.
Is T6N16AHM3/H compatible with standard SMT reflow profiles?
Yes, T6N16AHM3/H meets MSL Level 1 per J-STD-020 with a maximum peak reflow temperature of 260 °C, allowing direct placement into standard lead-free reflow ovens without pre-baking. Its DFN3820A package and matte tin terminations comply fully with J-STD-002 solderability requirements.
Does T6N16AHM3/H support automatic optical inspection (AOI)?
Yes, T6N16AHM3/H features side-wettable flanks on its DFN3820A package, enabling full solder-joint inspection using standard AOI systems. This eliminates the need for X-ray verification and supports zero-defect quality goals in automotive electronics manufacturing where the T6N16AHM3/H is deployed.
What is the thermal resistance from junction to mount for T6N16AHM3/H?
The typical thermal resistance from junction to mount (RθJM) for T6N16AHM3/H is 5 °C/W, measured per JEDEC® 51-14 using the transient dual interface method. This low value enables efficient heat transfer to the PCB copper pour, supporting sustained operation at TJ = 185 °C in high-ambient automotive environments.
How does T6N16AHM3/H perform under high-temperature storage conditions?
T6N16AHM3/H is rated for storage temperatures from -65 °C to +185 °C and maintains parameter stability after 1000 hours at 150 °C per AEC-Q101 stress testing. Its junction passivation design prevents IR increase or VBR shift during long-term high-temperature exposure - a key requirement for under-hood applications where the T6N16AHM3/H is used.
