Product details
Overview
T6N15CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 15.0 V nominal breakdown voltage (VBR), 12.8 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs), designed for automotive-grade ESD and surge protection of sensor signal lines and MOSFET gates.
For engineers reviewing the T6N15CAHM3/H datasheet, T6N15CAHM3/H pinout, T6N15CAHM3/H application, or T6N15CAHM3/H equivalent, this page delivers verified AEC-Q101-qualified TVS parameters, DFN3820A terminal mapping, clamping performance at 21.2 V under 28.3 A surge, and direct alternatives for automotive electronics protection design.
Technical Context
This device implements passivated anisotropic rectifier technology in a leadless DFN3820A package with side-wettable flanks, enabling AOI-compatible automated placement and solder joint inspection. Its bidirectional configuration provides symmetrical clamping for AC-coupled or differential signal paths without polarity constraints.
Rated for continuous operation up to TJ = 185 °C and qualified per AEC-Q101, the T6N15CAHM3/H supports high-reliability automotive environments where thermal derating and long-term stability under transient stress are critical - including engine control units, ADAS sensor interfaces, and body electronics modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 14.3 / 15.0 / 15.8 V - ensures reliable triggering above system operating voltage while accommodating manufacturing tolerance |
| VWM | 12.8 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA, compatible with 12 V automotive supply rails |
| VC @ IPPM | 21.2 V - clamping voltage at 28.3 A peak pulse current, limiting protected circuit stress during 600 W transients |
| IPPM (10/1000 μs) | 28.3 A - surge current handling capacity validated per IEC 61000-4-5 waveform standards |
| TJ max | +185 °C - enables operation in under-hood environments without thermal shutdown or parameter drift |
| ESD immunity | ±30 kV contact discharge per IEC 61000-4-2 - protects against human-body-model ESD events in assembly and field use |
| Package | DFN3820A - 3.95 mm × 2.18 mm × 0.88 mm low-profile footprint with side-wettable flanks for solder-joint inspection |
Pinout & Package
DFN3820A package: 2-terminal, bidirectional configuration with no cathode marking; terminals are symmetric and non-polarized. Dimensions: 3.95 mm × 2.18 mm × 0.88 mm (L × W × H), 0.70 mm pitch, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Common connection point for symmetrical transient clamping - interchangeable with Terminal 2 due to bidirectional structure |
| Terminal 2 | Anode/Cathode (bidirectional) | Second terminal completing the TVS junction - no polarity distinction; both terminals function identically in AC or differential protection |

Applications
| Automotive Sensor Signal Protection | Engine Control Unit (ECU) Power Input |
|---|---|
Use Scenario: Protecting LIN/CAN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive switching transients in vehicle cabins. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential signal pairs or single-ended lines to clamp surges before reaching sensitive analog front-ends. Use Value: Limits clamping voltage to 21.2 V at 28.3 A, preventing damage to 3.3 V or 5 V interface ICs while maintaining signal integrity under ISO 7637-2 Pulse 1/2a/3a stress. | Use Scenario: Safeguarding 12 V input rails of ECUs against battery reverse connection, jump-start spikes, and alternator load dump (ISO 16750-2). IC Role / Device Role / Timing Role: Primary overvoltage clamp installed upstream of DC/DC converters and LDO regulators to absorb 600 W pulses. Use Value: Withstands 185 °C junction temperature and maintains 12.8 V stand-off during normal operation, ensuring no false triggering during cold-cranking or cranking transients. |
| ADAS Camera Module Interface | Body Control Module (BCM) I/O Protection |
Use Scenario: Shielding FPD-Link III or GMSL serial video interfaces between radar/camera sensors and domain controllers from ESD and cable discharge events. IC Role / Device Role / Timing Role: Low-capacitance TVS (CJ ≈ 100–200 pF typical at VWM) placed directly at connector entry points to minimize signal distortion. Use Value: Clamps 30 kV ESD strikes per IEC 61000-4-2 without latch-up or parametric shift, preserving high-speed video timing margins up to 3 Gbps. | Use Scenario: Securing GPIO, wake-up inputs, and LIN slave node pins in BCMs exposed to harness-level transients during door actuation or lighting load switching. IC Role / Device Role / Timing Role: Compact DFN3820A TVS mounted adjacent to connectors to provide localized protection with minimal PCB area. Use Value: 0.88 mm height allows placement under connectors or near edge-mount components, reducing trace inductance and improving clamping response time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15CA | DO-214AC package (SMA), higher RθJA (190 °C/W), lower IPPM (24.7 A), same VBR/VC specs | Less suitable for space-constrained automotive modules; requires larger PCB footprint and lacks side-wettable flanks for AOI | Select when legacy SMA layout exists and AEC-Q101 is not required; not drop-in for DFN3820A footprints |
| SMCJ15CA | DO-214AB package (SMC), 1500 W rating, larger size (7.11 mm × 6.22 mm), higher VC (24.4 V) | Better for high-energy industrial transients but incompatible with automotive miniaturization goals and automated optical inspection | Choose only when surge energy exceeds 600 W; requires full PCB redesign due to 3× larger footprint and different thermal path |
Compared with SMAJ15CA and SMCJ15CA, the T6N15CAHM3/H delivers identical clamping performance in a 3.95 mm × 2.18 mm AEC-Q101-qualified package with side-wettable flanks - enabling AOI, supporting under-hood thermal demands, and fitting modern automotive sensor module layouts without compromise.

FAQ
What is the breakdown voltage tolerance of the T6N15CAHM3/H?
The T6N15CAHM3/H has a ±5 % breakdown voltage tolerance, specified as 14.3 V (min), 15.0 V (typ), and 15.8 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports robust design margins in automotive 12 V systems where VWM must remain ≥12.8 V to avoid false triggering during cranking.
Is the T6N15CAHM3/H suitable for protecting CAN FD interfaces?
Yes, the T6N15CAHM3/H is suitable for CAN FD interface protection due to its 21.2 V clamping voltage at 28.3 A, low leakage (<1.0 μA at 12.8 V), and bidirectional symmetry - all critical for maintaining signal integrity on high-speed differential buses. Its DFN3820A package minimizes parasitic inductance, and AEC-Q101 qualification confirms suitability for automotive network layers including CAN FD.
Does the T6N15CAHM3/H require a heatsink in standard automotive applications?
No, the T6N15CAHM3/H does not require an external heatsink in standard automotive applications. Its DFN3820A package features RθJM = 5–6.5 °C/W and RθJA = 140–175 °C/W on FR4 with standard footprint, and its 600 W peak pulse rating is designed for transient-only dissipation. Continuous power handling remains negligible due to low leakage (<1 μA), making heatsinking unnecessary even at +125 °C ambient.
How does the T6N15CAHM3/H compare to older SMA-style TVS diodes in terms of manufacturability?
The T6N15CAHM3/H improves manufacturability over SMA-style TVS diodes via its DFN3820A package with side-wettable flanks - enabling automated optical inspection (AOI) of solder joints without X-ray, whereas SMA packages require post-reflow visual or X-ray verification. Its 0.88 mm profile also supports ultra-thin modules, and MSL Level 1 rating eliminates bake steps, reducing line downtime and cost versus legacy DO-214AC solutions.
What is the maximum surge current the T6N15CAHM3/H can handle at elevated temperature?
At TA = 100 °C, the T6N15CAHM3/H retains ~65 % of its 25 °C IPPM rating (28.3 A), delivering approximately 18.4 A for 10/1000 μs pulses per Figure 2 derating curve. This is confirmed by Vishay's thermal derating data and supports sustained operation in under-hood locations where ambient temperatures exceed 85 °C without compromising surge margin.
