Product details
Overview
T6N15CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 15.0 V nominal breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs). It delivers 28.3 A peak pulse current (IPPM) and clamps to 21.2 V at rated surge, supporting automotive-grade protection of sensor signal lines and MOSFET gates.
For engineers reviewing the T6N15CAHM3/I datasheet, T6N15CAHM3/I pinout, T6N15CAHM3/I application, or T6N15CAHM3/I equivalent, key selection factors include its AEC-Q101 qualification, 185 °C junction temperature rating, side-wettable DFN3820A footprint for AOI compatibility, and ±5 % VBR tolerance for precise overvoltage thresholding in safety-critical ECUs.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable bidirectional clamping without polarity marking. Its DFN3820A package enables low-profile mounting (0.88 mm height) and thermal resistance of RθJA = 140–175 °C/W on FR4 PCBs.
Designed for high-reliability automotive environments, it meets IEC 61000-4-2 ESD immunity (±30 kV contact/air) and MSL Level 1 reflow (260 °C peak), with TJ max = 185 °C and halogen-free, RoHS-compliant construction per HM3 suffix.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 14.3 / 15.0 / 15.8 V - defines precise clamping onset under 1 mA test current, enabling accurate transient threshold alignment |
| VWM | 12.8 V - maximum continuous reverse working voltage before leakage exceeds 1 μA, ensuring no false triggering during normal operation |
| IPPM (10/1000 μs) | 28.3 A - peak surge current capability that determines survivability against ISO 7637-2 Pulse 1/2a/5a transients in 12 V vehicle systems |
| VC @ IPPM | 21.2 V - clamped voltage during full-rated surge, limiting stress on downstream ICs to safe levels below their absolute maximum ratings |
| PPPM | 600 W - peak pulse power handling capacity, directly tied to energy absorption (E = P × t) for standardized 10/1000 μs waveform compliance |
| TJ max | +185 °C - extended junction temperature rating enabling placement near heat sources (e.g., power modules) without derating penalties |
| ESD Rating | ±30 kV (IEC 61000-4-2) - ensures robustness against human-body-model electrostatic discharge during assembly and field service |
Pinout & Package
DFN3820A package: 2-terminal, leadless, side-wettable flanks, no cathode band (bidirectional), matte tin-plated terminals solderable per J-STD-002/JESD 22-B102, compatible with SMP (DO-220AA) outline.
| Pin/Terminal | Circuit Role | Design Meaning |

IC Role / Device Role / Timing Role: Low-capacitance (<100 pF typical at 0 V) bidirectional TVS placed inline with differential pairs to preserve signal integrity. Use Value: Maintains <1.5 dB insertion loss up to 1 GHz due to minimal junction capacitance, avoiding video artifacts or timing skew in high-speed serial links. | Use Scenario: Protecting 12 V power inputs of surround-view camera modules exposed to lightning-induced surges and alternator ripple in exterior mounting locations. IC Role / Device Role / Timing Role: Primary overvoltage suppression stage upstream of DC/DC converters and image sensor power rails. Use Value: Withstands repeated 600 W pulses without degradation, ensuring >15-year field life under ISO 16750-2 Category IV stress profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15CA | DO-214AC (SMA) package, 1.9 mm height, RθJA ≈ 50 °C/W higher, non-AEC-Q101 rated | Limited to industrial/commercial use; unsuitable for under-hood automotive deployment due to lower TJ max (150 °C) | Select when cost sensitivity outweighs automotive qualification and board space allows larger footprint |
| TPSMD15CA | DO-214AB (SMC) package, 2.3 mm height, 1500 W PPPM, same VBR/VC but higher IPPM (65 A) | Used where higher single-pulse energy absorption is needed (e.g., alternator load dump), but incompatible with AOI and DFN-reflow profiles | Choose for heavy-duty power line protection where PCB real estate permits larger case and thermal mass is available |
Compared with SMAJ15CA and TPSMD15CA, T6N15CAHM3/I uniquely combines AEC-Q101 qualification, side-wettable DFN3820A for automated inspection, and 185 °C operation - making it the only option qualified for compact, high-reliability automotive signal-line protection without layout or process compromises.

FAQ
What is the breakdown voltage tolerance of T6N15CAHM3/I?
The T6N15CAHM3/I has a ±5 % breakdown voltage tolerance, specified as 14.3 V (min) to 15.8 V (max) at 1 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports reliable overvoltage threshold setting in automotive safety-critical circuits where deviation could compromise system-level fault response.
Is T6N15CAHM3/I suitable for lead-free reflow soldering?
Yes, T6N15CAHM3/I is qualified for lead-free reflow with a maximum peak temperature of 260 °C per J-STD-020 MSL Level 1. Its DFN3820A package features matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, and the HM3 suffix confirms JESD 201 Class 2 whisker resistance - essential for high-yield SMT assembly in automotive electronics.
Does T6N15CAHM3/I require polarity-aware PCB layout?
No, T6N15CAHM3/I is a bidirectional TVS diode with no cathode band or polarity marking. Its symmetrical internal structure allows either terminal to serve as anode or cathode depending on transient polarity, eliminating orientation constraints during automated placement and simplifying PCB routing for differential or AC-coupled signal lines.
What is the thermal resistance from junction to mount (RθJM) for T6N15CAHM3/I?
The T6N15CAHM3/I has a typical RθJM of 5 °C/W and maximum of 6.5 °C/W, measured using JEDEC® 51-14 transient dual-interface method. This low value is achieved only when the exposed thermal pad is fully soldered to a dedicated PCB copper pour - critical for sustaining 600 W surges without exceeding the 185 °C junction limit in high-power automotive applications.
How does T6N15CAHM3/I compare to standard SMA-package TVS diodes in automotive use?
T6N15CAHM3/I differs from SMA-package alternatives by offering AEC-Q101 qualification, 185 °C junction rating, side-wettable flanks for AOI, and 0.88 mm profile - whereas SMA variants like SMAJ15CA lack automotive qualification, have higher RθJA, and cannot meet modern zero-defect manufacturing requirements. The T6N15CAHM3/I is therefore the designated solution for next-generation automotive modules where reliability, miniaturization, and process control are non-negotiable.
