Product details
Overview
T6N82CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 77.9 V minimum breakdown voltage, 70.1 V standoff voltage, and 113 V maximum clamping voltage at 5.3 A peak pulse current under 10/1000 μs waveform - designed for automotive-grade ESD and surge protection of sensor signal lines and power rails.
For engineers reviewing the T6N82CAHM3/H datasheet, T6N82CAHM3/H pinout, T6N82CAHM3/H application, or T6N82CAHM3/H equivalent, this device delivers AEC-Q101-qualified transient suppression with 600 W peak pulse power, 185 °C junction rating, and side-wettable DFN footprint compatible with AOI and automated placement in high-reliability automotive electronics.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and low-leakage performance. Its bidirectional configuration enables symmetrical clamping across both polarities without cathode marking, supporting robust protection against inductive switching transients and lightning-induced surges.
The DFN3820A package provides low thermal resistance (RθJM = 5 °C/W typ.) and meets MSL Level 1 with 260 °C lead-free reflow compatibility. It achieves 30 kV ESD immunity per IEC 61000-4-2 (contact and air discharge) while maintaining <1.0 μA reverse leakage at VWM up to 150 °C.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ85CA | DO-214AC package; higher RθJA (190 °C/W); 85 V nominal VBR; 113 V VC at 5.3 A | Larger footprint (4.5 × 2.7 mm), not AOI-compatible; lower thermal performance limits high-density layouts | Select when legacy through-hole or larger SMT layout exists and AEC-Q101 is not mandatory |
| SMCJ85CA | DO-214AB package; 600 W rating; 85 V nominal VBR; 125 V VC at 4.8 A; RθJA ≈ 150 °C/W | Higher clamping voltage increases stress on protected ICs; unsuitable for tight-margin 12 V systems | Choose only if board space allows larger 7.1 × 6.2 mm package and clamping margin permits 125 V peak |
Compared with SMAJ85CA and SMCJ85CA, the T6N82CAHM3/H offers superior thermal management (RθJM = 5 °C/W), smaller footprint (3.95 × 2.18 mm), and verified AEC-Q101 qualification - making it optimal for next-generation automotive electronics where size, reliability, and manufacturability are critical.

FAQ
What is the breakdown voltage tolerance of the T6N82CAHM3/H?
The T6N82CAHM3/H has a ±5 % breakdown voltage tolerance, specified as 77.9 V (min), 82.0 V (nominal), and 86.1 V (max) at 1.0 mA test current. This tight tolerance ensures predictable clamping onset across production lots and temperature ranges, critical for protecting sensitive automotive electronics without premature conduction.
Is the T6N82CAHM3/H suitable for 24 V automotive systems?
Yes, the T6N82CAHM3/H is suitable for 24 V automotive systems. With a 70.1 V standoff voltage (VWM) and 185 °C maximum junction temperature, it safely operates across double-battery transients and load-dump conditions while maintaining low leakage (<1.0 μA) even at elevated temperatures - meeting ISO 7637-2 and ISO 16750-2 requirements.
Does the T6N82CAHM3/H require a heatsink for 600 W pulse handling?
No, the T6N82CAHM3/H does not require an external heatsink for single 10/1000 μs pulses. Its DFN3820A package delivers low junction-to-mount thermal resistance (RθJM = 5 °C/W typ.), enabling effective heat transfer to the PCB copper pour. Continuous or repetitive surges require thermal design validation using the derating curve in Figure 2 of the datasheet.
How does the side-wettable flank design of the T6N82CAHM3/H improve manufacturing yield?
The side-wettable flanks on the T6N82CAHM3/H enable reliable Automated Optical Inspection (AOI) of solder fillets without X-ray imaging. This allows early detection of insufficient solder, bridging, or misalignment during SMT assembly - directly improving first-pass yield and reducing field failure risk in high-volume automotive production.
Can the T6N82CAHM3/H replace older SMAJ or SMCJ series TVS diodes in existing designs?
The T6N82CAHM3/H is not a direct pin-to-pin replacement for SMAJ or SMCJ series due to its DFN3820A footprint and 2-terminal bidirectional layout. While electrically comparable, PCB redesign is required to accommodate the 3.95 mm × 2.18 mm land pattern and side-wettable terminations - but the upgrade delivers better thermal performance, smaller size, and AEC-Q101 assurance.
