Product details
Overview
T6N33CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 33.0 V nominal breakdown voltage (±5 %), 28.2 V stand-off voltage, and 600 W peak pulse power (10/1000 μs). It delivers 13.1 A peak pulse current and clamps to 45.7 V at that current, supporting automotive-grade protection of sensor signal lines and MOSFET gates under lightning and inductive switching transients.
For engineers reviewing the T6N33CAHM3/I datasheet, T6N33CAHM3/I pinout, T6N33CAHM3/I application, or T6N33CAHM3/I equivalent, key selection criteria include its AEC-Q101 qualification, TJ = 185 °C rating, side-wettable DFN3820A footprint for AOI, and bidirectional clamping performance validated per IEC 61000-4-2 (30 kV contact/air discharge).
Technical Context
This TVS diode uses passivated anisotropic rectifier technology optimized for high-temperature stability and low-leakage operation. Its bidirectional configuration enables symmetrical transient suppression without polarity constraints, and its junction passivation ensures reliability under thermal cycling up to +185 °C.
The device is rated for 600 W peak pulse power under the standardized 10/1000 μs waveform and exhibits 45.7 V clamping voltage at 13.1 A IPPM - a critical parameter for ensuring downstream ICs remain below absolute maximum ratings during surge events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (Nom) | 33.0 V ±5 % - defines precise voltage threshold at which avalanche conduction begins under 1 mA test current |
| VWM | 28.2 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| IPPM | 13.1 A - peak surge current it safely shunts during 10/1000 μs transient without damage |
| VC @ IPPM | 45.7 V - clamped voltage seen by protected circuit during full-rated surge, limiting stress on downstream components |
| PPPM | 600 W - peak transient power dissipation capability under standard 10/1000 μs waveform |
| TJ max | +185 °C - enables operation in under-hood automotive environments and high-reliability industrial control systems |
| ESD Rating | 30 kV (IEC 61000-4-2 contact/air) - meets stringent electrostatic discharge immunity requirements for automotive ECUs |

Applications
| Automotive Sensor Protection | Power MOSFET Gate Protection |
|---|---|
Use Scenario: Protecting LIN/CAN bus sensor nodes (e.g., temperature, pressure, position) from load dump and ESD in vehicle cabins and powertrain compartments. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential signal pair or supply rail to clamp transients before they reach analog front-end or MCU input pins. Use Value: Maintains signal integrity under 30 kV ESD and 10/1000 μs surges while operating continuously at TJ = 150 °C ambient. | Use Scenario: Safeguarding gate oxide of high-side N-channel MOSFETs in 12 V/24 V automotive power switches against Miller-induced voltage spikes. IC Role / Device Role / Timing Role: Low-capacitance TVS connected between gate and source to suppress dv/dt-induced overshoot without slowing switching speed.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33CA | DO-214AC (SMA) package; higher RθJA (150 °C/W); VC = 53.3 V @ 11.3 A; not AEC-Q101 qualified | Less suitable for space-constrained automotive PCBs; limited to industrial or consumer-grade designs | Select when legacy SMA footprint reuse is prioritized over thermal performance and automotive qualification |
| TPSMD33CA | DO-214AB (SMC) package; VC = 53.3 V @ 11.3 A; AEC-Q101 qualified; larger footprint (7.11 × 6.22 mm) | Acceptable for under-hood use but requires >2× board area vs. DFN3820A; higher mounting height | Choose only if existing SMC layout prevents DFN adoption and thermal derating margin permits |
Compared with SMAJ33CA and TPSMD33CA, the T6N33CAHM3/I offers superior thermal resistance (RθJM = 5 °C/W), lowest profile (0.88 mm), and verified AOI compatibility - making it the optimal choice for next-generation automotive modules where density, reliability, and automated inspection are mandatory.

FAQ
What is the breakdown voltage tolerance of the T6N33CAHM3/I?
The T6N33CAHM3/I has a breakdown voltage tolerance of ±5 %, with a nominal VBR of 33.0 V (min 31.4 V, max 34.7 V at 1 mA test current). This tight tolerance ensures consistent clamping behavior across production lots and supports precise system-level surge margining in safety-critical automotive designs.
Is the T6N33CAHM3/I suitable for automotive applications?
Yes, the T6N33CAHM3/I is AEC-Q101 qualified, rated for TJ = -65 °C to +185 °C, and manufactured with halogen-free, RoHS-compliant materials. Its side-wettable DFN3820A package and 30 kV IEC 61000-4-2 ESD rating make it fully compliant for use in engine control units, ADAS sensors, and body electronics modules.
What does the "HM3" suffix indicate in T6N33CAHM3/I?
The "HM3" suffix in T6N33CAHM3/I denotes AEC-Q101 qualification (H), halogen-free/RoHS-compliant construction (M), and JESD 201 Class 2 whisker resistance (3). The "I" indicates 13" tape-and-reel packaging (14,000 units per reel), distinguishing it from the "H" variant (7" reel, 3,500 units).
How does the clamping voltage of T6N33CAHM3/I compare to its stand-off voltage?
The T6N33CAHM3/I has a VWM of 28.2 V and clamps to 45.7 V at its rated 13.1 A peak pulse current. This 17.5 V differential provides sufficient margin above VWM to avoid false triggering during normal operation while ensuring protected circuits remain below 46 V during worst-case transients.
Can T6N33CAHM3/I replace SMAJ33CA in an existing design?
T6N33CAHM3/I is not a direct pin-compatible replacement for SMAJ33CA due to differing packages (DFN3820A vs. DO-214AC). While both provide 33 V bidirectional suppression, the T6N33CAHM3/I requires PCB layout revision to accommodate its 3.95 mm × 2.18 mm footprint, though it delivers superior thermal performance and automotive qualification.
