Product details
Overview
T6N24AHM3/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, rated for 24 V nominal breakdown voltage (VBR = 22.8–25.2 V), 600 W peak pulse power (10/1000 μs), and 185 °C maximum junction temperature - designed for automotive-grade ESD and surge protection of sensor signal lines and MOSFET gates.
For engineers reviewing the T6N24AHM3/I datasheet, T6N24AHM3/I pinout, T6N24AHM3/I application, or T6N24AHM3/I equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance values, clamping performance at IPPM, and side-wettable flank compatibility with AOI inspection - all critical for high-reliability automotive PCB design and production validation.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology with junction passivation optimized for stable clamping under repetitive surge stress. Its unidirectional configuration enables precise reverse-biased transient suppression on DC-biased signal or power rails without forward conduction interference.
Rated for TJ = –65 °C to +185 °C and qualified per AEC-Q101, the T6N24AHM3/I supports automotive under-hood applications where thermal derating above 25 °C must be calculated using its 0.085 %/°C VBR temperature coefficient - validated across the full operating range per JEDEC 51-2A and 51-14 test methods.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 22.8 / 24.0 / 25.2 V - ensures reliable turn-on before downstream IC damage at 24 V nominal rail |
| VWM | 20.5 V - maximum continuous reverse standoff voltage compatible with 24 V systems |
| IPPM (10/1000 μs) | 18.1 A - peak surge current capability enabling IEC 61000-4-5 Level 4 compliance |
| VC @ IPPM | 33.2 V - clamping voltage limits transient overshoot to safe margin below 36 V-rated components |
| RθJA / RθJM | 140–175 / 5–6.5 °C/W - low junction-to-mount thermal resistance enables direct PCB copper pour heatsinking |
| ESD immunity | ±30 kV contact & air discharge (IEC 61000-4-2) - eliminates need for secondary ESD stages in sensor interfaces |
| MSL level | Level 1 (260 °C peak reflow) - supports standard lead-free SMT assembly without moisture sensitivity concerns |
Pinout & Package
Package: DFN3820A - 2-terminal, leadless, side-wettable flank package (3.95 mm × 2.18 mm × 0.88 mm), halogen-free, RoHS-compliant, AEC-Q101 qualified. Cathode marked by color band; anode connected to exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (thermal pad) | Common cathode return path & primary heat dissipation node | Must be soldered to ≥100 mm² internal or external copper pour for RθJM ≤6.5 °C/W performance |
| Cathode (top-side terminal) | Transient current sink during overvoltage events | Connected to protected line (e.g., CAN_H, LIN, sensor output); polarity-sensitive placement required |
Key Features
| Feature | Design Value |
|---|---|
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joint quality on both sidewalls - critical for zero-defect automotive manufacturing |
| Junction passivation | Prevents parametric drift and leakage increase after 1000+ surge cycles at 80 % of rated IPPM |
| TJ = 185 °C rating | Supports operation in engine control units (ECUs) and ADAS modules without thermal derating up to +150 °C ambient |
| Unidirectional clamping | Eliminates forward conduction during normal 24 V rail operation while maintaining fast <1 ns response to transients |
| DFN3820A footprint | Direct drop-in replacement for SMP (DO-220AA) packages - no PCB redesign needed when upgrading from legacy TVS |
Applications
| Automotive Sensor Protection | CAN Bus Line Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, and position sensors in engine bay modules subject to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor output and microcontroller ADC input to clamp transients before signal conditioning stage. Use Value: Clamps 33.2 V at 18.1 A surge, preserving 12-bit ADC accuracy and preventing latch-up in 3.3 V or 5 V interface ICs. |
Use Scenario: Safeguarding CAN_H and CAN_L differential pair against ESD and coupled surges in body control modules and gateway ECUs. IC Role / Device Role / Timing Role: One T6N24AHM3/I per line (CAN_H to GND, CAN_L to GND) providing bidirectional protection via two unidirectional devices. Use Value: 30 kV ESD immunity and 600 W surge rating maintain CAN FD bit timing integrity (<1 ns jitter impact) during transient events. |
| 12 V/24 V Power Rail Clamp | MOSFET Gate Protection |
Use Scenario: Secondary overvoltage clamp on 24 V supply rails feeding infotainment head units and ADAS camera modules. IC Role / Device Role / Timing Role: Parallel-mounted TVS across input capacitor to suppress load dump spikes exceeding 40 V without triggering upstream OVP ICs. Use Value: 20.5 V VWM allows stable operation during cold-crank (6.5 V) and load dump (up to 35 V), with 33.2 V clamping limiting rail excursion. |
Use Scenario: Gate-source protection of N-channel high-side switches driving solenoids and relays in transmission control units. IC Role / Device Role / Timing Role: Connected between gate and source to absorb Miller-induced voltage spikes during fast switching transitions. Use Value: Low 0.88 mm profile fits tight gate-drive layout; 185 °C rating matches MOSFET junction temperature limits during sustained PWM operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/57T | DO-214AC package; 24 V VBR; 400 W PPPM; RθJA = 50 °C/W higher; not AEC-Q101 qualified | Larger footprint (4.5 × 2.7 mm); unsuitable for AOI; limited to industrial-grade automotive interiors | Select when cost priority outweighs space constraints and AEC-Q101 compliance is not required |
| SMCJ24AHE3/57T | DO-214AB package; same 24 V VBR; 1500 W PPPM; 2.4 mm height; MSL level 1 but no side-wettable flanks | Higher surge capacity but incompatible with AOI; requires manual solder joint inspection | Choose only if system-level surge testing exceeds 600 W and board area permits larger package |
Compared with SMAJ24A-E3/57T and SMCJ24AHE3/57T, the T6N24AHM3/I delivers superior manufacturability (AOI-compatible), tighter thermal management (RθJM ≤6.5 °C/W), and certified automotive qualification - making it the preferred choice for safety-critical under-hood electronics where reliability and process control are non-negotiable.

FAQ
What is the exact breakdown voltage tolerance for T6N24AHM3/I?
The T6N24AHM3/I has a ±5 % breakdown voltage tolerance, confirmed by its "A" suffix in the part number. At 25 °C, its VBR is specified as 22.8 V (min), 24.0 V (nom), and 25.2 V (max) at 1.0 mA test current - ensuring predictable turn-on behavior across production lots and temperature ranges.
Is T6N24AHM3/I qualified for automotive use per AEC-Q101?
Yes, the T6N24AHM3/I is fully AEC-Q101 qualified, as indicated by the "H" in its ordering code and explicitly stated in Vishay document 98432. It meets stress test requirements including HTGB, AC/DC life test, and temperature cycling - with qualification data traceable to Vishay's certified automotive test labs.
Does T6N24AHM3/I support automatic optical inspection (AOI)?
Yes, the T6N24AHM3/I uses a DFN3820A package with side-wettable flanks, enabling full-spectrum AOI of solder fillets on both lateral edges. This feature is documented in Vishay's mechanical drawings and verified per J-STD-020 MSL level 1 reflow compatibility - essential for zero-defect automotive SMT lines.
What is the maximum clamping voltage of T6N24AHM3/I at rated surge current?
The T6N24AHM3/I clamps to 33.2 V at its rated peak pulse current of 18.1 A (10/1000 μs waveform), as specified in the Electrical Characteristics table of Vishay document 98432. This value is measured at TA = 25 °C and remains stable up to TJ = 150 °C per derating curves in Figure 2.
Can T6N24AHM3/I replace DO-220AA (SMP) package TVS diodes without PCB changes?
Yes, the T6N24AHM3/I is mechanically compatible with the SMP (DO-220AA) outline per Vishay's documentation, sharing identical pad layout dimensions and thermal pad geometry. Its DFN3820A footprint allows direct substitution in existing designs - provided solder paste volume and reflow profile are adjusted for leadless package requirements.
