Product details
Overview
T6N47CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 47 V nominal breakdown voltage (±5 %), 40.2 V stand-off voltage, 64.8 V clamping voltage at 9.3 A peak pulse current, and 600 W peak pulse power (10/1000 μs). It delivers automotive-grade ESD protection for sensor signal lines and MOSFET gate drivers under high-temperature operation up to 185 °C.
For engineers reviewing the T6N47CAHM3/H datasheet, T6N47CAHM3/H pinout, T6N47CAHM3/H application, or T6N47CAHM3/H equivalent, this page provides verified electrical parameters, AEC-Q101 qualification status, DFN3820A package dimensions, clamping performance at rated IPPM, and direct alternatives for automotive transient suppression design.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for low-leakage bidirectional clamping. Its junction passivation enables stable operation at TJ = 185 °C and supports MSL Level 1 reflow compatibility (260 °C peak).
The device features side-wettable flanks for AOI inspection and is halogen-free, RoHS-compliant, and qualified to AEC-Q101. Its single-channel DFN3820A configuration delivers 30 kV IEC 61000-4-2 contact/air discharge immunity without polarity marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nom) | 47 V ±5 % - ensures precise triggering above system operating voltage while maintaining margin against false clamping |
| VWM | 40.2 V - maximum continuous reverse voltage before leakage exceeds 1 μA, compatible with 36 V automotive supply rails |
| VC @ IPPM | 64.8 V - clamping voltage at 9.3 A, limiting downstream IC stress during 600 W transients |
| IPPM | 9.3 A - peak surge current capability under 10/1000 μs waveform, derated linearly above 25 °C ambient |
| TJ max | +185 °C - enables placement near heat sources in engine control units and ADAS modules |
| ESD Rating | 30 kV (IEC 61000-4-2) - protects CAN, LIN, and sensor interfaces from human-body-model surges |
| Package | DFN3820A - 3.95 mm × 2.18 mm footprint with side-wettable flanks for automated optical inspection |
Pinout & Package
DFN3820A is a 2-terminal, leadless, bidirectional package with no cathode band. Terminals are matte tin-plated and solderable per J-STD-002 and JESD 22-B102. Polarity is non-applicable due to symmetrical construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Interchangeable connection point - either terminal serves as input or return path for transient energy |
| Terminal 2 | Anode/Cathode (bidirectional) | Paired terminal completing low-inductance clamping loop across protected line and ground or rail |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal paths without polarity constraints |
| Side-wettable flanks | Supports automated optical inspection (AOI) of solder joints on both lateral edges of DFN3820A package |
| AEC-Q101 qualification | Validates reliability for automotive powertrain, chassis, and ADAS applications under temperature cycling and HTRB stress |
| 185 °C junction rating | Permits placement in high-temperature zones (e.g., near power converters) without thermal derating penalties |
| MSL Level 1 | Allows unlimited floor life and single-reflow processing at 260 °C peak without moisture-induced failure |
Applications
| Automotive Sensor Protection | CAN Bus Transient Suppression |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, and position sensors in engine control modules exposed to load-dump and inductive switching noise. IC Role / Device Role / Timing Role: Bidirectional TVS clamping element placed between sensor output and microcontroller ADC input. Use Value: Limits transient overvoltage to ≤64.8 V during 9.3 A surges, preserving 12-bit ADC accuracy and preventing latch-up in downstream signal conditioning ICs. | Use Scenario: Safeguarding CAN_H and CAN_L lines in body control modules against ESD events and battery reverse-connection transients. IC Role / Device Role / Timing Role: Low-capacitance (typ. 120 pF at 0 V) bidirectional clamp installed differential-mode across CAN bus pair. Use Value: Maintains signal integrity with <1 ns response time and prevents CAN controller damage from 30 kV IEC 61000-4-2 discharges. |
| Power MOSFET Gate Protection | Infotainment Display Interface |
Use Scenario: Shielding high-side N-channel MOSFET gates in 48 V DC-DC converters from Miller-induced voltage spikes during fast switching transitions. IC Role / Device Role / Timing Role: Clamp connected between gate and source to suppress dv/dt-induced overshoot exceeding VGS absolute maximum rating.

IC Role / Device Role / Timing Role: Single-channel TVS placed on each differential pair (CLK, DATA0–DATA3) adjacent to display driver IC. Use Value: Provides 30 kV ESD immunity with <0.5 pF added capacitance per line, preserving signal rise/fall times and eye diagram compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ47A-E3/5A | DO-214AC package, 47 V VBR, 600 W PPPM, but larger footprint (4.3 × 2.6 mm) and no AEC-Q101 qualification | Limited to industrial or consumer PCBs where space and automotive qualification are not required | Select when legacy through-hole or larger SMD layouts preclude DFN3820A adoption |
| TPSMD47CA | DO-218AB package, same 47 V VBR and 600 W rating, AEC-Q101 qualified, but 1.7 mm height vs. 0.88 mm for T6N47CAHM3/H | Suitable for high-power board-level protection where thermal mass outweighs profile constraints | Choose when higher surge current handling (12.3 A IPPM) and lower RθJA (110 °C/W) justify taller package |
Compared with SMAJ47A-E3/5A and TPSMD47CA, the T6N47CAHM3/H offers the lowest profile (0.88 mm), smallest footprint (3.95 × 2.18 mm), and full AEC-Q101 compliance - making it optimal for space-constrained automotive modules requiring zero-height optimization and process-compatible AOI.

FAQ
What is the clamping voltage of the T6N47CAHM3/H at its rated peak pulse current?
The T6N47CAHM3/H has a maximum clamping voltage (VC) of 64.8 V at its rated peak pulse current (IPPM) of 9.3 A under the standard 10/1000 μs waveform. This value is measured per Figure 3 in Vishay document 98489 and defines the upper voltage limit imposed on protected circuitry during surge events.
Is the T6N47CAHM3/H qualified for automotive use?
Yes, the T6N47CAHM3/H is AEC-Q101 qualified, as confirmed by the HM3 suffix in its ordering code and explicitly stated in the Vishay datasheet revision 17-Oct-2023. It meets automotive reliability requirements including temperature cycling, high-temperature reverse bias, and humidity testing.
Does the T6N47CAHM3/H have polarity markings on the package?
No, the T6N47CAHM3/H is a bidirectional TVS diode and carries no cathode band or polarity marking on the DFN3820A package. Its symmetrical construction allows installation in either orientation across protected lines without functional impact.
What is the maximum operating junction temperature for the T6N47CAHM3/H?
The T6N47CAHM3/H supports a maximum junction temperature (TJ) of +185 °C, enabling reliable operation in under-hood automotive environments and near high-power components. This rating is validated per JEDEC JESD22-A108 and reflected in thermal derating curves in the datasheet.
How does the DFN3820A package of the T6N47CAHM3/H support automated optical inspection?
The DFN3820A package of the T6N47CAHM3/H features side-wettable flanks - exposed copper terminations along both long edges - allowing AOI systems to verify solder joint quality without requiring X-ray inspection. This design complies with IPC-J-STD-020 and supports high-yield SMT assembly.
