Product details
Overview
T6N100CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, rated for 100 V breakdown voltage (VBR), 85.5 V working voltage (VWM), and 600 W peak pulse power (10/1000 μs), designed to protect automotive sensor signal lines and MOSFET gates against lightning-induced transients and inductive switching surges.
For engineers reviewing the T6N100CAHM3/H datasheet, T6N100CAHM3/H pinout, T6N100CAHM3/H application, or T6N100CAHM3/H equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal derating behavior, clamping performance at 4.4 A IPPM, and DFN3820A mechanical compatibility with AOI-capable side-wettable flanks.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for junction stability up to TJ = 185 °C, enabling operation in under-hood automotive environments. Its bidirectional configuration provides symmetrical clamping for AC-coupled or floating signal paths without polarity constraints.
The device delivers 137 V maximum clamping voltage (VC) at 4.4 A peak pulse current (IPPM) under 10/1000 μs waveform, with <1.0 μA reverse leakage at VWM and 6.0 μA at 150 °C - critical for low-power sensor interface integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 95.0 / 100 / 105 V - ensures reliable conduction onset above system operating voltage while accommodating ±5 % tolerance |
| VWM | 85.5 V - maximum continuous reverse voltage before significant leakage, compatible with 80 V nominal automotive bus systems |
| PPPM (10/1000 μs) | 600 W - sustains high-energy transients without failure, supporting ISO 7637-2 Pulse 5a robustness requirements |
| IPPM | 4.4 A - peak surge current capability directly tied to clamping voltage of 137 V, defining protection margin for downstream ICs |
| TJ max | +185 °C - enables placement near heat sources (e.g., powertrain ECUs) without derating loss or reliability degradation |
| ESD immunity | ±30 kV contact discharge (IEC 61000-4-2) - eliminates need for secondary ESD protection on exposed connectors |
| RθJA | 140–175 °C/W - quantifies thermal bottleneck on standard FR4 PCB; dictates minimum copper area for sustained surge duty |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ100CA | DO-214AC package; higher RθJA (190 °C/W); 600 W rating; VC = 156 V at 3.8 A | Through-hole mounting; less suitable for AOI; larger footprint (4.5 × 2.7 mm) limits high-density layouts | Select when legacy through-hole assembly is required or when higher clamping voltage is acceptable for non-safety-critical circuits |
| SMCJ100CA | DO-214AB package; 1500 W rating; VC = 165 V at 9.1 A; RθJA = 130 °C/W | Higher power handling but 7.1 × 6.2 mm footprint incompatible with compact DFN-restricted designs | Choose for systems requiring >600 W surge capacity where board space permits larger SMC package |
Compared with SMAJ100CA and SMCJ100CA, the T6N100CAHM3/H offers superior board-level integration via DFN3820A's side-wettable flanks and 0.88 mm profile, tighter clamping (137 V vs. ≥156 V), and guaranteed AEC-Q101 qualification - making it the preferred choice for new automotive electronics requiring zero-defect manufacturability and thermal resilience.

FAQ
What is the clamping voltage of the T6N100CAHM3/H at its rated peak pulse current?
The T6N100CAHM3/H has a maximum clamping voltage (VC) of 137 V at 4.4 A peak pulse current (IPPM) 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 - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the T6N100CAHM3/H qualified for automotive applications?
Yes, the T6N100CAHM3/H is AEC-Q101 qualified, as confirmed by the HM3 suffix in its ordering code and explicitly stated in Vishay's datasheet revision 17-Oct-2023. It undergoes stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD per JESD22 standards - making it suitable for deployment in engine control units, ADAS sensors, and other safety-relevant automotive subsystems.
Does the T6N100CAHM3/H have polarity markings on the package?
No, the T6N100CAHM3/H has no cathode band or polarity marking because it is a bidirectional TVS diode. The DFN3820A package features two identical terminals with symmetrical electrical behavior - either terminal may connect to the protected line or reference rail without affecting clamping performance or reliability.
What is the thermal resistance junction-to-ambient (RθJA) for the T6N100CAHM3/H?
The T6N100CAHM3/H has a typical RθJA of 140 °C/W and a maximum of 175 °C/W when mounted on a standard FR4 PCB per JEDEC 51-2A guidelines. This parameter determines how much the junction temperature rises above ambient under steady-state or repetitive surge conditions - essential for calculating safe operating area in thermally constrained automotive modules.
Can the T6N100CAHM3/H replace older SMAJ100CA parts in existing designs?
The T6N100CAHM3/H is not a pin-compatible replacement for SMAJ100CA due to differing packages (DFN3820A vs. DO-214AC) and thermal profiles. While both offer 600 W surge rating and 100 V nominal breakdown, the T6N100CAHM3/H requires updated PCB layout, stencil design, and reflow profile - but delivers lower clamping voltage (137 V vs. 156 V) and AEC-Q101 assurance not present in the SMAJ series.
