Overview
6DFN75CA-M3/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) in DFN3820A package, designed for clamping ESD and surge transients on signal/power lines. It features 75 V nominal breakdown voltage (VBR), 64.1 V stand-off voltage (VWM), 104 V maximum clamping voltage (VC) at 5.8 A peak pulse current, and 600 W peak pulse power (10/1000 μs). Used to protect MOSFET gates, sensor interfaces, and USB/UART lines in industrial and telecom equipment.
For engineers reviewing the 6DFN75CA-M3/I datasheet, 6DFN75CA-M3/I pinout, 6DFN75CA-M3/I application, or 6DFN75CA-M3/I equivalent, key selection criteria include clamping voltage margin relative to protected IC's absolute maximum rating, thermal resistance (RθJA = 140–175 °C/W), bidirectional symmetry, and MSL Level 1 reflow compatibility.
Technical Context
This TVS diode employs anisotropic rectifier technology with junction passivation optimized for low leakage and stable breakdown. Its bidirectional configuration enables symmetrical clamping without polarity constraints, supporting AC-coupled or differential signal protection.
Rated for 175 °C maximum junction temperature and compliant with IEC 61000-4-2 (±30 kV contact/air discharge), it delivers robust immunity in harsh environments. The DFN3820A package provides side-wettable flanks for automated optical inspection and high-density PCB layouts.

Use Scenario: Protecting analog output (4–20 mA) and digital I/O lines of pressure/temperature sensors exposed to relay switching noise and field wiring surges. IC Role / Device Role / Timing Role: Bidirectional TVS placed directly at connector entry point to clamp transients before reaching ADC or microcontroller GPIO. Use Value: 104 V clamping voltage ensures protected MCU I/O remains below its 120 V absolute max rating; 600 W rating handles repetitive 1 kV/500 A surge events per IEC 61000-4-5. |
Use Scenario: Safeguarding D+ and D− lines of embedded USB host controllers against ESD events during cable insertion and lightning-induced common-mode surges. IC Role / Device Role / Timing Role: Low-capacitance TVS (CJ ≈ 100 pF at 0 V) placed adjacent to USB connector to minimize signal integrity impact. Use Value: ±30 kV IEC 61000-4-2 compliance meets USB-IF ESD test requirements; bidirectional symmetry avoids polarity misplacement errors during layout. |
| Telecom Power Rail Clamp | MOSFET Gate Driver Transient Suppression |
|
Use Scenario: Clamping induced transients on 48 V DC telecom power distribution rails feeding remote radio units and baseband processors. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing fast-rising line-to-ground surges (e.g., from nearby lightning strikes) before they propagate to DC/DC converters. Use Value: 64.1 V VWM allows safe operation across full 48 V ±10 % input range; 175 °C TJMAX supports operation near hot-running power components. |
Use Scenario: Preventing gate oxide rupture in high-side N-channel MOSFETs driven by PWM controllers in motor control inverters. IC Role / Device Role / Timing Role: TVS placed between gate and source to clamp Miller-induced voltage spikes during high dV/dt switching transitions. Use Value: 75 V VBR aligns with typical 60–80 V MOSFET VGS ratings; low leakage (<1 μA) avoids gate drive current loss during idle states. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
