Product details
Overview
T6N24AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, featuring 24.0 V nominal breakdown voltage (VBR), 20.5 V stand-off voltage (VWM), 33.2 V maximum clamping voltage at 18.1 A peak pulse current, and 600 W peak pulse power rating (10/1000 μs). It is AEC-Q101 qualified and rated for TJ = 185 °C, designed for automotive sensor signal-line protection.
For engineers reviewing the T6N24AHM3/H datasheet, T6N24AHM3/H pinout, T6N24AHM3/H application, or T6N24AHM3/H equivalent, this page delivers verified electrical parameters, package dimensions, thermal resistance values, ESD immunity (30 kV contact/air), and automotive-grade reliability context - all specific to the T6N24AHM3/H variant with HM3 halogen-free, RoHS-compliant, whisker-tested termination.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and low-leakage performance. Its unidirectional configuration provides precise overvoltage clamping on positive transients while maintaining sub-1.0 μA reverse leakage at VWM and 25 °C.
The DFN3820A package enables automated optical inspection via side-wettable flanks and supports high-reliability mounting on FR4 PCBs with RθJA = 140–175 °C/W and RθJM = 5–6.5 °C/W. It meets MSL Level 1 and withstands 260 °C reflow peak temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (nom) | 24.0 V - ensures reliable triggering above system operating voltage without false clamping |
| VWM | 20.5 V - maximum continuous reverse voltage before leakage exceeds 1.0 μA at 25 °C |
| VC @ IPPM | 33.2 V - clamping voltage at 18.1 A limits protected IC stress during 10/1000 μs surge |
| PPPM | 600 W - peak transient energy absorption capability under standardized waveform |
| TJ max | +185 °C - enables operation in under-hood automotive environments without derating |
| ESD immunity | 30 kV contact/air per IEC 61000-4-2 - protects against human-body-model and system-level electrostatic events |
| RθJM | 5–6.5 °C/W - low junction-to-mount thermal resistance supports efficient heat transfer to PCB copper |
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, cathode marked by color band; heatsink (exposed pad) is anode.
| Pin/Terminal | Circuit Role | Design Meaning |

|---|---|
| AEC-Q101 qualification | Validated for automotive electronics per stress test requirements including HTOL, TC, UHAST, and ESD |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joint quality without X-ray |
| TJ = 185 °C rating | Supports uninterrupted operation in engine control units, ADAS sensors, and powertrain modules |
| Low-profile height (0.88 mm) | Reduces board stack height and improves mechanical robustness in space-constrained modules |
| Halogen-free & RoHS-compliant (HM3) | Meets automotive environmental compliance standards and JESD201 Class 2 whisker resistance |
Applications
| Automotive Sensor Signal Protection | Power Supply Rail Clamping |
|---|---|
Use Scenario: Protecting LIN/CAN bus transceiver inputs and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and ground to clamp positive surges to ≤33.2 V while maintaining <1.0 μA leakage at 20.5 V. Use Value: Prevents damage to 24 V-rated microcontrollers and ADC front-ends without affecting normal signal integrity or DC bias. | Use Scenario: Safeguarding 24 V supply rails feeding motor drivers and solenoid controllers against ISO 7637-2 pulse 1/2a/5a transients. IC Role / Device Role / Timing Role: Primary clamping device across rail-to-ground, absorbing up to 600 W for 1 ms to limit rail sag and downstream component overstress. Use Value: Maintains system uptime by preventing brownout-induced resets and MOSFET gate oxide failure during battery disconnection events. |
| ADAS Camera Module ESD Protection | Industrial CAN Node Interface |
Use Scenario: Shielding high-speed image sensor data lines (e.g., MIPI CSI-2) in forward-facing cameras from ESD events during assembly and field operation. IC Role / Device Role / Timing Role: Low-capacitance TVS (typ. <50 pF at 0 V) placed inline with differential pairs to suppress 30 kV contact discharge without signal distortion. Use Value: Preserves signal rise/fall times and eye diagram integrity while meeting IEC 61000-4-2 immunity requirements. | Use Scenario: Protecting isolated CAN transceivers in industrial PLC backplanes exposed to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Secondary protection stage after common-mode choke, clamping differential-mode surges to <33.2 V before reaching transceiver inputs. Use Value: Extends mean time between failures (MTBF) in harsh factory environments where >1 kV ring-wave transients occur regularly. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/57T | DO-214AC package; higher RθJA (~110 °C/W); VC = 38.9 V at same IPPM; no AEC-Q101 qualification | Not suitable for under-hood automotive use; limited to ambient ≤125 °C; requires larger PCB footprint | Select only for cost-sensitive industrial designs where AEC-Q101 and 185 °C operation are not required |
| TPSMD24A | DO-214AB package; VBR = 24.0–26.5 V; VC = 38.0 V; PPPM = 600 W; AEC-Q101 qualified but TJ max = 175 °C | Lower thermal margin than T6N24AHM3/H; less suitable for sustained high-temp zones near engines | Acceptable for cabin or chassis-mounted modules where junction temperature remains below 175 °C |
Compared with SMAJ24A-E3/57T and TPSMD24A, the T6N24AHM3/H offers superior thermal robustness (185 °C vs. ≤175 °C), lower clamping voltage (33.2 V vs. ≥38.0 V), and compact DFN3820A packaging - making it the preferred choice for next-generation automotive sensor nodes requiring minimal board area and extended temperature resilience.

FAQ
What is the exact breakdown voltage range for T6N24AHM3/H?
The T6N24AHM3/H has a guaranteed breakdown voltage (VBR) range of 22.8 V (min) to 25.2 V (max) at 1.0 mA test current, with a nominal value of 24.0 V. This ±5 % tolerance is confirmed in the Electrical Characteristics table of Vishay document 98432, revision 10-Nov-2023, and applies strictly to the T6N24AHM3/H variant within its specified operating conditions.
Is T6N24AHM3/H compatible with lead-free reflow processes?
Yes, T6N24AHM3/H is fully compatible with lead-free reflow processes. It meets JEDEC J-STD-020 MSL Level 1 and supports a maximum peak reflow temperature of 260 °C, as verified in the Mechanical Data section of the official Vishay datasheet (document 98432). The HM3 suffix confirms halogen-free, RoHS-compliant, and Pb-free termination.
Does T6N24AHM3/H have a defined junction capacitance value?
No specific junction capacitance (CJ) value is published for T6N24AHM3/H in the primary datasheet. Figure 4 shows typical CJ curves for the T6NxxA family versus breakdown voltage, indicating ~35–45 pF at 0 V bias for 24 V-class devices, but no discrete value is assigned to T6N24AHM3/H. Designers should refer to the family curve or characterize empirically for high-speed signal line applications.
How does the clamping performance of T6N24AHM3/H compare to older SMAJ series TVS diodes?
T6N24AHM3/H clamps at 33.2 V under 18.1 A (10/1000 μs), which is 5.7 V lower than SMAJ24A-E3/57T (38.9 V at same IPPM). This tighter clamping directly reduces stress on downstream 24 V-rated ICs. Combined with its DFN3820A package's lower inductance and thermal resistance, T6N24AHM3/H delivers superior transient response and thermal margin compared to SMAJ24A-E3/57T.
Can T6N24AHM3/H be used in bidirectional configurations?
No, T6N24AHM3/H is strictly unidirectional, as confirmed by its "A" polarity suffix and explicit labeling in the PRIMARY CHARACTERISTICS table. It conducts only during positive transients relative to its cathode. For bidirectional protection, Vishay offers separate "CA" variants (e.g., T6N24CAHM3/H), which are distinct part numbers with different internal construction and electrical behavior.
