Product details
Overview
T6N62CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 62 V nominal breakdown voltage (VBR), 53.0 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 gate drivers.
For engineers reviewing the T6N62CAHM3/H datasheet, T6N62CAHM3/H pinout, T6N62CAHM3/H application, or T6N62CAHM3/H equivalent, key selection criteria include AEC-Q101 qualification, TJ = 185 °C operation, side-wettable DFN3820A footprint for AOI, and clamping voltage of 85.0 V at 7.1 A IPPM - critical for robust CAN/LIN bus and ADAS sensor interface protection.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable bidirectional clamping under repetitive transients, with thermal resistance RθJA up to 175 °C/W and RθJM as low as 5 °C/W for efficient heat transfer to PCB copper. Its junction passivation enables reliable operation at TJ = 185 °C, meeting automotive high-temperature stability requirements.
The device exhibits 1.0 μA max reverse leakage at VWM = 53.0 V and 1.0 μA at 150 °C, ensuring minimal standby current in always-on vehicle modules. It meets IEC 61000-4-2 ±30 kV contact/air discharge and is rated for MSL Level 1 reflow (260 °C peak).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 58.9 / 62.0 / 65.1 V - ensures precise overvoltage triggering within ±5 % tolerance for predictable system-level surge response |
| VWM | 53.0 V - maximum continuous operating voltage before leakage exceeds 1.0 μA, compatible with 48 V automotive supply rails |
| IPPM | 7.1 A (10/1000 μs) - peak surge current capability enabling protection against ISO 7637-2 Pulse 1/2a/5a transients |
| VC @ IPPM | 85.0 V - clamping voltage limiting downstream IC stress during 600 W transient events |
| TJ max | +185 °C - supports under-hood placement and long-term reliability in AEC-Q101-compliant automotive modules |
| Package | DFN3820A (3.95 × 2.18 × 0.88 mm) - low-profile, leadless, side-wettable flanks enable automated optical inspection and high-density layout |
| ESD Rating | ±30 kV (IEC 61000-4-2) - protects exposed connectors and sensor interfaces from human-body-model discharges |
Pinout & Package
DFN3820A package: 2-terminal, bidirectional configuration with no polarity marking; terminals are matte tin-plated for J-STD-002 solderability and JESD 22-B102 compliance; flange dimensions support standard FR4 mounting per JEDEC 51-2A.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ64A-E3/57T | DO-214AC (SMA) package, 64 V VBR, 55.1 V VWM, 600 W PPPM, but only TJ = 150 °C and not AEC-Q101 qualified | Lacks automotive qualification and side-wettable flanks; requires X-ray for solder joint verification | Select when cost-sensitive industrial designs prioritize legacy footprint compatibility over AOI and extended temperature range |
| SMCJ64A-QH | DO-214AB (SMC) package, 64 V VBR, 55.1 V VWM, 1500 W PPPM, AEC-Q101 qualified, but 7.1 mm × 6.2 mm footprint vs. DFN3820A's 3.95 mm × 2.18 mm | Higher power handling but 5× larger board area; unsuitable for space-constrained ADAS camera modules | Select when higher surge margin is needed in non-size-critical under-dash ECUs, accepting larger PCB real estate and manual AOI limitations |
Compared with SMAJ64A-E3/57T and SMCJ64A-QH, the T6N62CAHM3/H uniquely combines AEC-Q101 qualification, 185 °C operation, side-wettable DFN3820A packaging, and 600 W surge capability in a 3.95 mm × 2.18 mm footprint - making it the only option for next-generation compact, high-reliability automotive sensor nodes requiring zero visual inspection gaps.

FAQ
What is the breakdown voltage tolerance of the T6N62CAHM3/H?
The T6N62CAHM3/H has a ±5 % breakdown voltage tolerance, confirmed by its "CA" suffix per Vishay's ordering nomenclature. Its VBR is specified as 58.9 V (min), 62.0 V (nom), and 65.1 V (max) at 1.0 mA test current - ensuring consistent clamping behavior across production lots and temperature ranges up to 150 °C.
Is the T6N62CAHM3/H suitable for use in under-hood automotive applications?
Yes, the T6N62CAHM3/H is explicitly rated for TJ = 185 °C and qualified to AEC-Q101, making it suitable for under-hood environments such as engine control units and transmission control modules. Its DFN3820A package provides low thermal resistance (RθJM = 5 °C/W), and its passivated die ensures stable VBR drift under prolonged high-temperature bias stress.
Does the T6N62CAHM3/H require a cathode marking on the package?
No, the T6N62CAHM3/H is a bidirectional TVS and carries no cathode band or polarity marking. As stated in the mechanical data section, "Polarity: no cathode band for bidirectional types." Both terminals are functionally identical, allowing flexible PCB layout and eliminating orientation-dependent assembly errors.
What is the maximum clamping voltage of the T6N62CAHM3/H at its rated peak pulse current?
The T6N62CAHM3/H has a maximum clamping voltage (VC) of 85.0 V at its rated peak pulse current (IPPM) of 7.1 A under the 10/1000 μs waveform. This value is measured per Figure 1 and Table 1 in Document Number 98489 and defines the upper voltage limit imposed on protected circuitry during worst-case surge events.
How does the DFN3820A package of the T6N62CAHM3/H support automated optical inspection?
The DFN3820A package of the T6N62CAHM3/H features side-wettable flanks - exposed copper terminations along the package edges - which reflect light uniformly during AOI. This enables high-confidence solder-joint inspection without X-ray, satisfying IPC-A-610 Class 3 requirements for automotive electronics and reducing post-SMT defect escape rates in high-volume production.
