Product details
Overview
T6N27CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 27.0 V nominal breakdown voltage (VBR), 23.1 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 T6N27CAHM3/I datasheet, T6N27CAHM3/I pinout, T6N27CAHM3/I application, or T6N27CAHM3/I equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal derating behavior, clamping performance at 16.0 A IPPM, and DFN3820A footprint compatibility with AOI-optimized side-wettable flanks.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve bidirectional clamping with low leakage (<1.0 μA at VWM) and high junction temperature capability (TJ = –65 °C to +185 °C). Its DFN3820A package enables automated placement and meets MSL Level 1 with 260 °C reflow peak.
The device operates as a single-channel, unidirectional-capable bidirectional suppressor - clamping transients above 25.7 V (min VBR) to ≤37.5 V (max VC at 16.0 A) while maintaining <1.0 μA reverse leakage up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 25.7 / 27.0 / 28.4 V - ensures reliable turn-on before system damage threshold in 24 V automotive circuits |
| VWM | 23.1 V - maximum continuous working voltage without leakage degradation |
| IPPM (10/1000 μs) | 16.0 A - peak surge current it safely shunts without failure |
| VC @ IPPM | 37.5 V - clamped voltage seen by protected IC during full-rated surge |
| PPPM | 600 W - transient energy absorption capacity under standard waveform |
| TJ max | +185 °C - supports under-hood automotive placement without thermal derating loss |
| ESD immunity | ±30 kV contact/air per IEC 61000-4-2 - eliminates need for secondary ESD stages |
Pinout & Package
DFN3820A package: 2.18 mm × 1.98 mm × 0.88 mm body, leadless, side-wettable flanks, matte tin-plated terminals, no cathode band (bidirectional).

Applications
| Automotive Sensor Protection | 24 V Power Rail Clamping |
|---|---|
Use Scenario: Protecting LIN/CAN 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 or IC input pins to limit transient excursions below IC absolute maximum ratings. Use Value: Maintains signal integrity with <1.0 μA leakage at 23.1 V and clamps 16.0 A surges to ≤37.5 V - preventing latch-up or gate oxide rupture in downstream ICs. | Use Scenario: Safeguarding 24 V supply rails feeding ADAS cameras, radar modules, and infotainment ECUs against ISO 7637-2 Pulse 1/2a/5a events. IC Role / Device Role / Timing Role: Primary transient suppression element mounted near power entry point, coordinated with bulk capacitance and upstream fusing. Use Value: Absorbs 600 W pulses without degradation while operating up to +185 °C - enabling compact placement near heat-generating components. |
| MOSFET Gate Protection | High-Temperature Industrial I/O |
Use Scenario: Shielding N-channel MOSFET gates in motor drivers and solenoid controllers from Miller-induced voltage spikes during fast switching. IC Role / Device Role / Timing Role: Low-capacitance (typ. <50 pF), fast-response TVS placed between gate and source to clamp dv/dt-induced overshoot. Use Value: Delivers 37.5 V clamping at 16.0 A with sub-1 ns response - limiting gate-source voltage to safe levels without adding propagation delay. | Use Scenario: Securing digital I/O lines in industrial PLCs and railway signaling systems exposed to lightning-induced surges in harsh ambient environments. IC Role / Device Role / Timing Role: Ruggedized discrete protector deployed across isolated fieldbus interfaces (RS-485, CAN FD) operating continuously at +125 °C ambient. Use Value: Sustains <1.0 μA leakage at elevated temperature and passes ±30 kV ESD - eliminating field failures due to latent overstress damage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ28A-E3/57T | DO-214AC package, 28 V VBR, 400 W PPPM, higher RθJA (190 °C/W), non-AEC-Q101 | Larger footprint, lower power rating, unsuitable for under-hood automotive use | Select only for cost-sensitive industrial PCBs where space and thermal constraints allow larger package |
| SMCJ28A-QH | DO-214AB package, 28 V VBR, 1500 W PPPM, AEC-Q101 qualified, but 7.11 mm × 6.22 mm body | Higher surge capacity but 5× larger area - incompatible with dense automotive layouts | Choose when system-level surge threat exceeds 600 W and board space permits larger case outline |
Compared with SMAJ28A-E3/57T and SMCJ28A-QH, the T6N27CAHM3/I uniquely balances AEC-Q101 compliance, 600 W capability, and ultra-compact DFN3820A footprint - making it the only option for space-constrained, high-reliability 24 V automotive signal line protection.

FAQ
What is the breakdown voltage tolerance of the T6N27CAHM3/I?
The T6N27CAHM3/I has a ±5 % breakdown voltage tolerance, specified as 25.7 V (min), 27.0 V (typ), and 28.4 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports robust design margins in 24 V automotive systems where overvoltage thresholds must be precisely controlled.
Is the T6N27CAHM3/I suitable for under-hood automotive applications?
Yes, the T6N27CAHM3/I 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 modules and transmission control units. Its DFN3820A package maintains mechanical and electrical integrity under thermal cycling and vibration stress per automotive qualification standards.
Does the T6N27CAHM3/I require polarity-aware PCB layout?
No, the T6N27CAHM3/I is a bidirectional TVS diode with no cathode band marking and symmetrical terminal functionality. Both terminals serve interchangeably as anode or cathode, allowing unrestricted orientation during automated placement and eliminating risk of reverse installation on PCBs.
What is the maximum clamping voltage of the T6N27CAHM3/I at rated surge current?
The maximum clamping voltage (VC) of the T6N27CAHM3/I is 37.5 V at 16.0 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is critical for ensuring downstream ICs remain within their absolute maximum ratings.
How does the DFN3820A package of the T6N27CAHM3/I support automated optical inspection?
The DFN3820A package of the T6N27CAHM3/I features side-wettable flanks - vertical metalized sidewalls that form visible, reflective solder fillets during reflow. This enables automated optical inspection (AOI) systems to reliably detect solder joint quality, voiding, and alignment without requiring X-ray or cross-section analysis - improving first-pass yield in high-volume automotive manufacturing.
