Product details
Overview
T6N75CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 75 V nominal breakdown voltage (VBR), 64.1 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 T6N75CAHM3/H datasheet, T6N75CAHM3/H pinout, T6N75CAHM3/H application, or T6N75CAHM3/H equivalent, this AEC-Q101 qualified TVS delivers verified 185 °C junction capability, side-wettable flanks for AOI, and clamping voltage of 104 V at 5.8 A IPPM - critical for robust transient suppression in high-reliability automotive electronics.
Technical Context
This device employs passivated anisotropic rectifier technology to achieve stable bidirectional clamping without cathode marking. Its DFN3820A package supports automated placement and meets MSL Level 1 with 260 °C lead-free reflow compatibility.
Rated for -65 °C to +185 °C operating junction temperature, it sustains 30 kV IEC 61000-4-2 contact discharge immunity and exhibits thermal resistance RθJA ≤ 175 °C/W on FR4 PCB - enabling reliable operation under sustained thermal stress in engine bay or ADAS modules.
Key Specifications

Applications
| Automotive Sensor Protection | Power MOSFET Gate Protection |
|---|---|
Use Scenario: Protecting LIN/CAN bus sensor nodes (e.g., wheel speed, pressure, temperature sensors) from load dump and inductive switching transients in 12 V vehicle architectures. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential signal pair or supply rail to clamp sub-100 ns spikes before they reach analog front-end or MCU inputs. Use Value: Clamps to 104 V at 5.8 A while maintaining 64.1 V stand-off - preserving signal integrity during normal operation and preventing latch-up in protected ASICs. | Use Scenario: Shielding gate oxide of high-side N-channel MOSFETs in automotive DC-DC converters and motor drivers from Miller-induced voltage overshoot during fast switching. IC Role / Device Role / Timing Role: Low-capacitance (<100 pF typical), fast-response TVS connected between gate and source to absorb dv/dt-induced transients before gate threshold is exceeded. Use Value: With 185 °C TJ max and 30 kV ESD rating, T6N75CAHM3/H withstands repeated surge events in high-temperature power stages without parametric drift. |
| Infotainment Display Interface | ADAS Camera Power Line Protection |
Use Scenario: Safeguarding LVDS or FPD-Link III video interface lines between head unit and TFT display from ESD and cable discharge events. IC Role / Device Role / Timing Role: Placed inline on each differential pair to suppress common-mode transients while minimizing signal distortion via low junction capacitance. Use Value: DFN3820A footprint minimizes board area impact; side-wettable flanks ensure solder joint quality verification on fine-pitch flex-rigid PCBs. | Use Scenario: Protecting 5 V or 12 V camera module power rails in surround-view systems exposed to ignition noise and alternator ripple. IC Role / Device Role / Timing Role: Mounted at connector entry point to divert >600 W surges (10/1000 µs) away from image sensor and ISP power domains. Use Value: 600 W peak pulse power rating and 104 V clamping enable compliance with ISO 7637-2 Pulse 5a load-dump immunity requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ75CA | DO-214AC (SMA) package, 1.9 mm height, higher RθJA (~190 °C/W), 600 W rating same | Through-hole or larger SMT footprint; less suitable for AOI or ultra-thin modules | Select when legacy layout or manual rework compatibility is prioritized over space and inspection efficiency |
| SMCJ75CA | DO-214AB (SMC) package, 2.3 mm height, 1500 W rating, higher clamping voltage (121 V) | Higher energy handling but larger size and slower response due to higher junction capacitance | Choose only when system-level surge tests exceed 600 W or require higher IPPM margin |
Compared with SMAJ75CA and SMCJ75CA, T6N75CAHM3/H offers the smallest footprint (3.95 mm × 2.18 mm), lowest profile (0.88 mm), and integrated AOI support - making it optimal for space-constrained, high-volume automotive PCBs where manufacturability and thermal performance are co-prioritized.

FAQ
What is the clamping voltage of T6N75CAHM3/H at its rated peak pulse current?
The T6N75CAHM3/H has a maximum clamping voltage (VC) of 104 V when subjected to its rated peak pulse current (IPPM) of 5.8 A under the standard 10/1000 µs waveform. This value is measured per Figure 3 in the official Vishay datasheet (Doc. #98489) and defines the upper voltage limit imposed on protected circuitry during surge events. It directly determines the safe operating margin for downstream components like microcontrollers or transceivers.
Is T6N75CAHM3/H compatible with lead-free reflow processes?
Yes, T6N75CAHM3/H is fully compatible with lead-free reflow processes, meeting MSL Level 1 per J-STD-020 with a maximum peak temperature of 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102 solderability standards, and the DFN3820A package is qualified for standard Pb-free reflow profiles without delamination or voiding concerns. The HM3 suffix confirms halogen-free, RoHS-compliant construction.
Does T6N75CAHM3/H have polarity markings for orientation during placement?
No, T6N75CAHM3/H does not have polarity markings. As a bidirectional TVS, it features symmetric terminals with no cathode band or anode indicator. Both terminals are functionally identical, allowing unrestricted orientation during automated placement. This simplifies pick-and-place programming and eliminates orientation-related assembly errors in high-speed SMT lines.
What is the maximum junction temperature rating for T6N75CAHM3/H, and how does it impact automotive use?
The T6N75CAHM3/H is rated for a maximum junction temperature (TJ) of +185 °C, validated per AEC-Q101 stress testing. This enables reliable operation in under-hood environments such as engine control units, transmission modules, and ADAS ECUs where ambient temperatures exceed 125 °C. The rating allows full 600 W surge capability up to 150 °C junction temperature before derating begins, per Figure 2 in the Vishay datasheet.
How does the DFN3820A package of T6N75CAHM3/H support automated optical inspection (AOI)?
The DFN3820A package of T6N75CAHM3/H features side-wettable flanks - exposed copper terminations along the package edges - which allow AOI systems to inspect solder fillet formation and wetting quality without requiring X-ray. This capability reduces post-reflow defect escapes in automotive manufacturing, supports IPC-A-610 Class 3 compliance, and eliminates the need for secondary inspection methods in high-volume SMT lines.
