Product details
Overview
T6N75CAHM3/I 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). It delivers 5.8 A peak pulse current and clamps to 104 V at rated surge, supporting automotive-grade protection of sensor signal lines and MOSFET gates under lightning and inductive switching transients.
For engineers reviewing the T6N75CAHM3/I datasheet, T6N75CAHM3/I pinout, T6N75CAHM3/I application, or T6N75CAHM3/I equivalent, this device is selected for high-reliability 185 °C junction operation, AEC-Q101 qualification, side-wettable flanks for AOI, and compatibility with SMP (DO-220AA) footprint constraints in space-constrained automotive ECUs.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for low-leakage, stable clamping across -65 °C to +185 °C. Its bidirectional configuration enables symmetrical transient suppression on AC-coupled or floating signal paths without polarity concerns.
The DFN3820A package provides 5 °C/W typical junction-to-mount thermal resistance and meets MSL Level 1 with 260 °C lead-free reflow peak. It achieves 30 kV ESD immunity per IEC 61000-4-2 (contact and air discharge), targeting robustness in harsh automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 71.3 / 75.0 / 78.8 V - Ensures reliable triggering above system operating voltage while maintaining margin against false clamping. |
| VWM | 64.1 V - Maximum continuous reverse working voltage compatible with 60 V nominal automotive supply rails. |
| IPPM (10/1000 μs) | 5.8 A - Sustains defined surge energy without degradation; derates linearly above 25 °C ambient. |
| VC @ IPPM | 104 V - Clamped voltage limits downstream IC stress during 600 W transient events. |

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-E3/5A (Vishay) | DO-214AC (SMA) package; 75 V VBR, 600 W rating, but 140 °C TJ max and no AEC-Q101 qualification. | Larger footprint (4.5 × 2.7 mm), higher RθJA (190 °C/W); suitable for industrial, not automotive under-hood. | Select when cost sensitivity outweighs space constraints and automotive qualification is unnecessary. |
| TPSMF7.0A-Q (ON Semiconductor) | DFN1006-2 package; 7.0 V VBR, 200 W rating, AEC-Q101 qualified, but lower voltage range and power handling. | Designed for 3.3 V/5 V logic rails; insufficient for 64.1 V VWM systems like 48 V architectures or CAN FD. | Use only for low-voltage microcontroller I/O protection-not a functional substitute for T6N75CAHM3/I's 64.1 V operating window. |
Compared with SMAJ75A-E3/5A and TPSMF7.0A-Q, the T6N75CAHM3/I uniquely combines 64.1 V stand-off capability, 185 °C junction rating, AEC-Q101 qualification, and DFN3820A footprint-enabling direct integration into next-generation automotive power domains where thermal, reliability, and space constraints converge.

FAQ
What is the maximum clamping voltage of the T6N75CAHM3/I at its rated peak pulse current?
The T6N75CAHM3/I clamps to a maximum of 104 V when subjected to its rated 5.8 A peak pulse current (10/1000 μs waveform). This value is measured under standardized test conditions per ANSI/IEEE C62.35 and is guaranteed across the full operating temperature range up to 185 °C junction temperature. The clamping performance ensures downstream ICs remain within safe voltage limits during surge events.
Is the T6N75CAHM3/I suitable for use in automotive under-hood applications?
Yes, the T6N75CAHM3/I is explicitly qualified to AEC-Q101 and rated for continuous operation up to +185 °C junction temperature, making it suitable for under-hood applications such as engine control units, transmission control modules, and battery management systems. Its DFN3820A package and halogen-free construction further align with automotive material compliance requirements.
Does the T6N75CAHM3/I have polarity markings on the package?
No, the T6N75CAHM3/I is a bidirectional TVS diode and carries no cathode band or polarity marking on the DFN3820A package. Both terminals are functionally identical, allowing flexible placement across differential lines (e.g., CAN_H/CAN_L) or single-ended paths without orientation constraints during automated assembly.
What is the thermal resistance from junction to mount (RθJM) for the T6N75CAHM3/I?
The T6N75CAHM3/I has a typical junction-to-mount thermal resistance (RθJM) of 5 °C/W, measured using the JEDEC® 51-14 transient dual interface method. This low value enables efficient heat transfer to the PCB copper pour or thermal pad, supporting sustained power dissipation in thermally demanding automotive environments.
How does the T6N75CAHM3/I compare to standard SMA package TVS diodes in terms of board space and manufacturability?
The T6N75CAHM3/I occupies 3.95 mm × 2.18 mm - approximately 55 % less area than the DO-214AC (SMA) package - while offering side-wettable flanks for full-spectrum AOI verification. Unlike SMA devices, it requires no post-reflow visual inspection or X-ray, reducing manufacturing cost and improving first-pass yield in high-volume automotive SMT lines.
