Product details
Overview
T6N68CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, featuring 68 V nominal breakdown voltage (VBR), 58.1 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 T6N68CAHM3/I datasheet, T6N68CAHM3/I pinout, T6N68CAHM3/I application, or T6N68CAHM3/I equivalent, key selection criteria include AEC-Q101 qualification, TJ = 185 °C operation, side-wettable flanks for AOI, and clamping voltage of 92.0 V at 6.5 A IPPM - critical for robust transient suppression in high-reliability automotive electronics.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for high-temperature stability and low leakage. Its bidirectional configuration enables symmetrical clamping across both polarities without polarity marking, supporting protection of AC-coupled or differential signal paths.
The DFN3820A package delivers low thermal resistance (RθJM = 5–6.5 °C/W) and meets MSL Level 1 (260 °C peak reflow), while its 0.88 mm profile and side-wettable flanks ensure compatibility with automated optical inspection and high-density PCB layouts.
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 |
|---|---|---|---|
| SMAJ64A-E3/57T | DO-214AC package; 64 V VWM; 100 W PPPM; unidirectional only | Lacks AEC-Q101 qualification and side-wettable flanks; unsuitable for automated AOI or automotive under-hood use | Select only for cost-sensitive industrial applications where 185 °C operation and automotive compliance are not required |
| SMCJ64CA | DO-214AB package; 64 V VWM; 1500 W PPPM; larger footprint (7.11 mm × 6.22 mm) | Higher power but incompatible with high-density SMT assembly; no MSL Level 1 rating | Choose when higher surge margin is needed and board space allows larger package |
Compared with SMAJ64A-E3/57T and SMCJ64CA, the T6N68CAHM3/I provides superior automotive readiness via AEC-Q101 qualification, tighter VBR tolerance (±5 %), and compact DFN3820A packaging - enabling smaller PCB area, better thermal coupling, and full process compatibility with modern SMT lines.

FAQ
What is the breakdown voltage tolerance of the T6N68CAHM3/I?
The T6N68CAHM3/I has a ±5 % breakdown voltage tolerance, specified as 64.6 V (min) to 71.4 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise system-level overvoltage margining in automotive designs where predictable protection thresholds are mandatory.
Is the T6N68CAHM3/I suitable for use in under-hood automotive applications?
Yes, the T6N68CAHM3/I is explicitly rated for TJ = –65 °C to +185 °C and is AEC-Q101 qualified, making it suitable for under-hood environments including engine control modules, transmission control units, and turbocharger actuators. Its DFN3820A package maintains mechanical and electrical integrity at sustained high temperatures without derating.
Does the T6N68CAHM3/I require a PCB polarity marking during layout?
No, the T6N68CAHM3/I is a bidirectional TVS with no cathode band or polarity marking. Both terminals are functionally identical, allowing placement in either orientation on the PCB - simplifying layout, reducing assembly errors, and eliminating orientation-dependent routing constraints in differential or AC-coupled signal protection schemes.
What is the maximum clamping voltage of the T6N68CAHM3/I at its rated peak pulse current?
The T6N68CAHM3/I exhibits a maximum clamping voltage (VC) of 92.0 V at its rated peak pulse current (IPPM) of 6.5 A under 10/1000 μs waveform conditions. This value defines the upper voltage limit imposed on protected circuitry during worst-case transients and is critical for ensuring downstream ICs remain within absolute maximum ratings.
How does the DFN3820A package of the T6N68CAHM3/I support automated optical inspection (AOI)?
The DFN3820A package of the T6N68CAHM3/I features side-wettable flanks - exposed copper terminations along the package edges - enabling standard AOI systems to verify solder fillet formation and wetting quality without requiring X-ray inspection. This reduces final test cost and improves yield in high-volume automotive electronics manufacturing.
