Product details
Overview
T6N30CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 30 V nominal breakdown voltage (VBR = 28.5–31.5 V), 25.6 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs). It delivers 14.5 A peak pulse current and clamps to 41.4 V at IPPM, operating up to +185 °C junction temperature for automotive-grade transient protection of sensor signal lines.
For engineers reviewing the T6N30CAHM3/I datasheet, T6N30CAHM3/I pinout, T6N30CAHM3/I application, or T6N30CAHM3/I equivalent, this device is selected for high-reliability, AEC-Q101-qualified ESD and surge suppression in space-constrained automotive ECUs where low-profile side-wettable DFN packaging enables AOI-compatible assembly and thermal robustness under sustained high-temperature operation.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for bidirectional clamping, delivering stable breakdown behavior across -65 °C to +185 °C. Its DFN3820A package features side-wettable flanks and meets MSL Level 1 (260 °C reflow), supporting automated placement and optical inspection in high-volume automotive PCB assembly.
The device exhibits 1.0 μA maximum reverse leakage at VWM (25.6 V) and 1.0 μA at 150 °C, with thermal resistance RθJA ≤ 175 °C/W and RθJM ≤ 6.5 °C/W - enabling effective heat dissipation in thermally dense layouts without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 28.5 / 30.0 / 31.5 V - defines reliable conduction onset under transient overvoltage, ±5 % tolerance ensures predictable clamping threshold |
| VWM | 25.6 V - maximum continuous working voltage before leakage exceeds 1.0 μA, sets safe operating margin below breakdown |
| IPPM (10/1000 μs) | 14.5 A - peak surge current it safely shunts without failure, directly determines protected circuit's surge withstand capability |
| VC @ IPPM | 41.4 V - clamped voltage during full-rated surge, limits stress on downstream ICs like automotive sensors or CAN transceivers |
| PPPM | 600 W - peak pulse power handling per standard 10/1000 μs waveform, validates suitability for ISO 7637-2 Pulse 1/2a/5a compliance |
| TJ max | +185 °C - maximum junction temperature rating, supports under-hood deployment and long-term reliability in high-ambient environments |
| ESD immunity | ±30 kV (IEC 61000-4-2 contact/air) - enables standalone ESD protection without additional discrete suppressors |
Pinout & Package
Package: DFN3820A - 2-terminal, leadless, halogen-free, RoHS-compliant, side-wettable flanks for AOI; dimensions 3.95 mm × 2.18 mm × 0.88 mm (L × W × H); no cathode band (bidirectional).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 185 °C junction rating | Supports operation in under-hood ambient temperatures up to +125 °C with sufficient thermal derating margin - extends lifetime in thermally aggressive locations |
| DFN3820A footprint compatibility | Matches SMP (DO-220AA) outline - allows drop-in replacement in legacy designs using larger packages while reducing board area by >50 % |
| Low-profile height (0.88 mm) | Enables integration beneath low-clearance shields or connectors - critical for compact ADAS camera modules and radar front-ends |
Applications
| Automotive Sensor Signal Protection | Infotainment USB/USB-C Port Protection |
|---|---|
Use Scenario: Protecting LIN/CAN bus signal lines and analog outputs of pressure, temperature, and position sensors in engine control units and battery management systems exposed to load dump and inductive switching transients.

| ADAS Camera Module Power Input | Electric Power Steering (EPS) Motor Driver Protection |
Use Scenario: Guarding 12 V input rails of CMOS image sensor modules against ISO 7637-2 Pulse 5a (50 V/100 ms) and load dump events in forward-facing cameras. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main power rail, conducting surge current away from LDOs and image processors during transients exceeding 25.6 V. Use Value: Limits rail voltage to 41.4 V during 14.5 A surges, preventing brownout reset or overvoltage damage to 1.2 V/1.8 V digital cores without requiring bulk capacitance redesign. | Use Scenario: Protecting gate drivers and current sense amplifiers in EPS motor control boards from inductive kickback generated by 3-phase BLDC motor commutation. IC Role / Device Role / Timing Role: Bidirectional TVS placed across half-bridge source nodes and ground, clamping negative-going spikes from freewheeling diodes and positive spikes from supply bounce.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30CA | DO-214AC (SMA) package, 30 V VBR, 600 W PPPM, but 1.5 mm height and no side-wettable flanks | Requires manual AOI or X-ray for solder joint verification; unsuitable for ultra-thin modules | Select when board-level rework accessibility is prioritized over automated inspection and height constraints |
| TPSMD30CA | DO-214AB (SMC) package, same 30 V VBR, higher 1500 W PPPM, but 2.3 mm height and 7.1 mm² footprint | Offers higher surge margin but occupies >3× PCB area; not AEC-Q101 qualified | Select only for non-automotive industrial applications needing higher single-pulse energy absorption |
Compared with SMAJ30CA and TPSMD30CA, T6N30CAHM3/I provides identical 30 V clamping performance in a 3.95 mm × 2.18 mm DFN3820A package with AEC-Q101 qualification, side-wettable flanks, and 0.88 mm profile - making it the sole option meeting automotive AOI, space, and reliability requirements simultaneously.

FAQ
What is the breakdown voltage tolerance of the T6N30CAHM3/I?
The T6N30CAHM3/I has a ±5 % breakdown voltage tolerance, with a specified range of 28.5 V (min) to 31.5 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage protection design margins in automotive applications where VBR directly impacts system-level surge immunity.
Is the T6N30CAHM3/I compatible with lead-free reflow processes?
Yes, the T6N30CAHM3/I is fully compatible with lead-free reflow processes, meeting J-STD-020 MSL Level 1 with a maximum peak temperature of 260 °C. Its matte tin-plated terminals and halogen-free molding compound ensure reliable solderability and intermetallic formation under standard Pb-free profiles used in automotive PCB assembly lines.
Does the T6N30CAHM3/I require orientation during placement?
No, the T6N30CAHM3/I does not require orientation during placement because it is a bidirectional TVS diode with no cathode marking or polarity designation. Both terminals are functionally identical, allowing unrestricted placement on PCBs - a key advantage for automated pick-and-place and reducing assembly errors in high-mix automotive manufacturing.
What is the maximum reverse leakage current of the T6N30CAHM3/I at elevated temperature?
The T6N30CAHM3/I specifies a maximum reverse leakage current of 1.0 μA at VWM = 25.6 V and TJ = 150 °C. This low, temperature-stable leakage ensures minimal power loss and avoids false triggering in always-on automotive circuits such as wake-up receivers or low-power sensor interfaces where quiescent current budgets are tightly constrained.
How does the DFN3820A package of the T6N30CAHM3/I improve thermal performance versus SMA packages?
The DFN3820A package of the T6N30CAHM3/I achieves RθJM ≤ 6.5 °C/W via its exposed thermal pad, which provides a direct low-resistance path to the PCB ground plane - outperforming SMA packages (RθJM typically >15 °C/W). This enables higher sustained surge duty cycles and extended operation at elevated ambient temperatures without thermal runaway, critical for under-hood deployments.
