Product details
Overview
6DFN75CA-M3/H from Vishay General Semiconductor is a bidirectional surface-mount TRANSZORB® transient voltage suppressor in DFN3820A package, with 75 V nominal breakdown voltage (VBR = 71.3–78.8 V), 64.1 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 µs). It clamps transients to ≤104 V at 5.8 A peak surge current and operates from –65 °C to +175 °C - deployed for ESD and lightning surge protection on sensor signal lines in industrial and automotive control units.
For engineers reviewing the 6DFN75CA-M3/H datasheet, 6DFN75CA-M3/H pinout, 6DFN75CA-M3/H application, or 6DFN75CA-M3/H equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, thermal resistance (RθJA = 140–175 °C/W), MSL Level 1 reflow compatibility, and side-wettable flanks for AOI validation.
Technical Context
This device implements an anisotropic rectifier structure with junction passivation optimized for low-leakage bidirectional clamping. Its single-channel configuration delivers symmetrical reverse/forward breakdown behavior without cathode marking, enabling simplified PCB layout in AC-coupled or differential signal paths.
Designed for automated SMT placement, the DFN3820A package features matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, and passes JESD 201 Class 2 whisker testing. Thermal performance relies on low RθJM (5–6.5 °C/W) to mounting pad, supporting high-reliability operation under repetitive surge stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 71.3 / 75.0 / 78.8 V - ensures reliable conduction onset above system operating voltage while maintaining margin against false triggering |
| VWM | 64.1 V - maximum continuous working voltage before leakage exceeds 1 μA, defining safe DC bias limit |
| VC @ IPPM | ≤104 V - clamping voltage at 5.8 A surge current; must be below protected IC's absolute max input rating |
| PPPM | 600 W (10/1000 µs) - peak transient energy handling capacity per standard waveform |

Applications
| Automotive Sensor Signal Protection | Industrial PLC Analog Input Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load-dump transients and ESD in engine control modules. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt surges before reaching precision front-end amplifiers or communication ICs. Use Value: Clamps 600 W transients to ≤104 V while maintaining <1 μA leakage at 64.1 V - preserving signal integrity and ADC accuracy in 12 V/24 V systems. | Use Scenario: Safeguarding 4–20 mA current loop inputs and ±10 V analog channels in programmable logic controllers exposed to relay switching noise and field wiring surges. IC Role / Device Role / Timing Role: Standoff voltage (64.1 V) exceeds typical industrial supply rails; clamping action activates only during fault conditions, avoiding interference with normal operation. Use Value: 175 °C max junction temperature and robust thermal resistance (RθJM = 5–6.5 °C/W) ensure reliability in enclosed, high-ambient cabinets without forced cooling. |
| Medical Imaging Data Interface Protection | Telecom Base Station RF Front-End Protection |
Use Scenario: Shielding high-speed serial links (e.g., LVDS, RS-485) between imaging sensors and processing boards from electrostatic discharge during handling and cable coupling. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed adjacent to connector to minimize signal distortion while meeting IEC 61000-4-2 ±30 kV compliance. Use Value: Side-wettable flanks enable full AOI coverage of solder joints - critical for zero-defect requirements in Class II medical device manufacturing. | Use Scenario: Guarding RF transceiver I/O pins and bias lines against lightning-induced surges entering via antenna ports or power feeds in outdoor small cells. IC Role / Device Role / Timing Role: Fast-response transient suppressor with sub-nanosecond turn-on, placed before LNA or PA stages to prevent gate oxide damage. Use Value: 600 W peak pulse power rating and 104 V clamping voltage provide sufficient margin over LTE/5G RF IC absolute maximum ratings (typically ≤120 V). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ75A-E3/57T | DO-214AC (SMA) package; higher RθJA (~150 °C/W); 75 V VBR, 600 W rating; unidirectional | Requires polarity-aware layout; less suitable for AC-coupled or differential lines without external diode pairing | Select when legacy SMA footprint exists and unidirectional protection suffices with external polarity management |
| SMCJ75CA | DO-214AB (SMC) package; same VBR/VWM; 1500 W rating; bidirectional; larger footprint (7.11 × 6.22 mm) | Higher surge capacity but incompatible with DFN3820A board space; better for high-energy industrial surge events | Choose when system-level surge tests exceed 600 W and PCB area permits larger package |
Compared with SMAJ75A-E3/57T and SMCJ75CA, the 6DFN75CA-M3/H uniquely combines bidirectional symmetry, ultra-low profile (0.88 mm), side-wettable flanks for AOI, and DFN3820A footprint - making it optimal for next-gen compact, automated, and high-reliability designs where polarity independence and process verification are mandatory.

FAQ
What is the exact breakdown voltage range for 6DFN75CA-M3/H?
The 6DFN75CA-M3/H has a guaranteed breakdown voltage range of 71.3 V (minimum) to 78.8 V (maximum) at 1.0 mA test current, with 75.0 V nominal. This ±5 % tolerance ensures predictable turn-on behavior while maintaining margin above its 64.1 V stand-off voltage - critical for avoiding false triggering in 48 V or 60 V system rails.
Does 6DFN75CA-M3/H require a heatsink for 600 W surge handling?
No, the 6DFN75CA-M3/H does not require an external heatsink for single-event 600 W (10/1000 µs) surges. Its thermal design relies on low junction-to-mount thermal resistance (RθJM = 5–6.5 °C/W) and proper PCB copper area (per JEDEC 51-14). Continuous or repetitive surges demand derating per Figure 2 in the datasheet, but standalone transients are handled within package limits.
Is 6DFN75CA-M3/H qualified to AEC-Q101?
Yes, the "H" suffix in 6DFN75CA-M3/H indicates AEC-Q101 qualification. This certification covers stress testing for automotive-grade reliability including temperature cycling, humidity bias HAST, and ESD - confirming suitability for under-hood and chassis-mounted applications where extended temperature range (–65 °C to +175 °C) and long-term stability are required.
How does the side-wettable flank feature benefit manufacturing of 6DFN75CA-M3/H?
The side-wettable flanks on the 6DFN75CA-M3/H enable full automated optical inspection (AOI) of solder fillet formation along the package edges - eliminating reliance on X-ray for void detection. This reduces final-test cost, improves first-pass yield, and supports zero-defect initiatives in high-volume automotive and medical manufacturing where solder joint integrity is mission-critical.
Can 6DFN75CA-M3/H replace older SMA or SMC package TVS diodes on the same PCB?
No, 6DFN75CA-M3/H cannot directly replace SMA or SMC packages due to different footprints and thermal profiles. While electrically comparable to SMAJ75A-E3/57T (unidirectional) or SMCJ75CA (bidirectional), its DFN3820A outline (3.95 mm × 2.18 mm) is incompatible with DO-214AC or DO-214AB land patterns. Layout redesign is required - though mechanical compatibility with SMP (DO-220AA) aids evaluation fixture reuse.
