Product details
Overview
T6N33AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, rated for 33 V nominal breakdown voltage (VBR = 31.4–34.7 V), 600 W peak pulse power (10/1000 μs), and 13.1 A peak pulse current, designed for automotive-grade ESD and surge protection of sensor signal lines and MOSFET gates.
For engineers reviewing the T6N33AHM3/H datasheet, T6N33AHM3/H pinout, T6N33AHM3/H application, or T6N33AHM3/H equivalent, this device delivers AEC-Q101 qualification, 185 °C junction temperature capability, side-wettable flanks for AOI, and precise clamping at 45.7 V under 13.1 A surge - critical for robust automotive electronics design and high-reliability industrial control interfaces.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for stable clamping performance across -65 °C to +185 °C. Its unidirectional configuration provides low-leakage reverse blocking (≤1.0 μA at 28.2 V) while enabling fast response to transients induced by inductive switching or ESD events.
The DFN3820A package integrates thermal resistance RθJM as low as 5 °C/W (typ.) to the mounting pad, supporting high-power transient dissipation without external heatsinking. It meets IEC 61000-4-2 ±30 kV contact/air discharge and is qualified per JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 31.4 / 33.0 / 34.7 V - ensures reliable triggering above system stand-off voltage while accommodating process variation |
| VWM | 28.2 V - maximum continuous reverse operating voltage compatible with 24 V automotive supply rails |
| VC @ IPPM | 45.7 V - clamps 13.1 A surge (10/1000 μs) within safe margin for 33 V-rated downstream ICs |
| PPPM | 600 W - sustains high-energy transients common in automotive load-dump and inductive kick scenarios |
| TJ max | +185 °C - enables operation in engine bay and powertrain modules without derating |
| ESD immunity | ±30 kV (IEC 61000-4-2) - protects against human-body-model and contact-discharge events in assembly and field use |
Pinout & Package
Package: DFN3820A - leadless, 2-terminal surface-mount package with side-wettable flanks (0.078 × 0.086 in / 1.98 × 2.18 mm), matte tin-plated terminals, halogen-free, RoHS-compliant, and AEC-Q101 qualified. Polarity marked by cathode band; anode connected to exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pad) | Common cathode reference and thermal path | Exposed copper pad serves as primary heat sink and must be soldered to PCB thermal plane for RθJM = 5 °C/W performance |
| Cathode (K) | Transient current sink during clamping | Connected to protected line; conducts surge current to ground/anode when VIN exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joint quality on both sidewalls - eliminates X-ray requirement for production line validation |
| AEC-Q101 qualification | Validated for automotive applications including powertrain, chassis, and ADAS sensor interfaces under extended temperature and reliability stress tests |
| Junction passivation | Stabilizes VBR drift over lifetime and temperature (αT = 0.089 %/°C), ensuring consistent clamping in harsh environments |
| MSL Level 1 rating | Allows unlimited floor life and reflow up to 260 °C peak - compatible with standard lead-free SMT processes without dry-pack handling |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump spikes and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground to clamp transients before they reach sensitive input pins. Use Value: Clamps 13.1 A surges to ≤45.7 V while maintaining <1.0 μA leakage at 28.2 V - preserves signal integrity and prevents false triggers in 24 V systems. | Use Scenario: Safeguarding digital input channels of programmable logic controllers against field-wiring transients and relay coil flyback. IC Role / Device Role / Timing Role: Standoff protector on 24 V DC input lines, absorbing repetitive 600 W pulses without degradation. Use Value: 185 °C max junction temperature and 140 °C/W RθJA allow sustained operation in enclosed cabinets without forced cooling. |
| Motor Drive Gate Protection | Automotive Lighting Control |
Use Scenario: Shielding high-side/low-side MOSFET gate drivers from Miller-induced voltage spikes during fast switching in BLDC inverters. IC Role / Device Role / Timing Role: Localized TVS at gate-source node to suppress dv/dt-induced ringing and prevent unintended turn-on. Use Value: Low capacitance (<50 pF at 0 V) avoids slowing gate drive edges; 45.7 V clamping prevents gate oxide breakdown on 30 V-rated FETs. | Use Scenario: Protecting LED driver ICs and LIN-controlled headlight modules from battery reverse-polarity and jump-start surges. IC Role / Device Role / Timing Role: Primary transient suppressor on 12 V supply rail upstream of DC-DC converters and linear regulators. Use Value: AEC-Q101 qualification and MSL Level 1 ensure compliance with automotive manufacturing and long-term field reliability requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A-E3/57T | DO-214AC package; higher RθJA (150 °C/W); VC = 53.3 V @ 10.3 A; no AEC-Q101 qualification | Not suitable for under-hood automotive use; limited to industrial or consumer PCBs with ample airflow | Select only if cost sensitivity outweighs thermal and qualification requirements; requires larger board area |
| TPSMF33A | DFN2510-10 package; lower PPPM (400 W); VC = 53.3 V @ 7.5 A; AEC-Q101 qualified | Lower surge capacity limits use to low-energy signal lines; insufficient for power-line or motor-drive protection | Prefer for space-constrained signal-level protection where 600 W is not required |
Compared with SMAJ33A-E3/57T and TPSMF33A, the T6N33AHM3/H uniquely combines 600 W surge rating, 185 °C operation, AEC-Q101 qualification, and DFN3820A's side-wettable flanks - making it the only option validated for high-power, high-temperature automotive power electronics protection with full AOI support.

FAQ
What is the exact breakdown voltage range for T6N33AHM3/H?
The T6N33AHM3/H has a guaranteed breakdown voltage range of 31.4 V (minimum) to 34.7 V (maximum) at 1.0 mA test current, with a nominal value of 33.0 V. This tolerance (±5 %) is specified per the "A" suffix in the part number and ensures predictable clamping onset across production lots and temperature extremes.
Is T6N33AHM3/H qualified for automotive applications?
Yes, the T6N33AHM3/H is fully AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and JESD201 Class 2 whisker-tested construction. It is approved for use in automotive powertrain, chassis, and body electronics where high-reliability transient suppression is mandated.
What is the maximum clamping voltage of T6N33AHM3/H under surge conditions?
The T6N33AHM3/H clamps to a maximum of 45.7 V when subjected to its rated 13.1 A peak pulse current (10/1000 μs waveform). This clamping voltage is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Does T6N33AHM3/H require special PCB layout considerations?
Yes - the DFN3820A package features an exposed anode thermal pad that must be connected to a minimum 100 mm² copper pour on the PCB for optimal thermal performance (RθJM = 5 °C/W). Side-wettable flanks also require compliant stencil design and reflow profile to ensure full solder fillet formation for AOI verification.
How does T6N33AHM3/H perform at elevated temperatures?
The T6N33AHM3/H maintains full specification compliance up to +185 °C junction temperature. Its VBR exhibits a positive temperature coefficient of +0.089 %/°C, meaning breakdown voltage increases predictably with temperature - a key advantage for stable clamping in hot under-hood environments.
