Product details
Overview
T6N24CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, featuring 24 V nominal breakdown voltage (VBR), 20.5 V stand-off voltage (VWM), 33.2 V clamping voltage at 18.1 A peak pulse current, and 600 W peak pulse power (10/1000 μs). It is AEC-Q101 qualified and rated for TJ = 185 °C, designed for automotive sensor signal-line protection against inductive switching transients.
For engineers reviewing the T6N24CAHM3/H datasheet, T6N24CAHM3/H pinout, T6N24CAHM3/H application, or T6N24CAHM3/H equivalent, key selection criteria include bidirectional clamping performance under 10/1000 μs surge, low-profile DFN3820A footprint with side-wettable flanks for AOI, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver stable bidirectional clamping across -65 °C to +185 °C junction temperature range. Its DFN3820A package enables high thermal conductivity via low RθJM (6.5 °C/W max) and supports automated optical inspection through side-wettable flanks.
The device operates with 1.0 mA test current, exhibits ≤1.0 μA reverse leakage at VWM (20.5 V), and maintains clamping voltage ≤33.2 V under 18.1 A 10/1000 μs surge - meeting IEC 61000-4-2 ±30 kV contact/air ESD immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/typ/max) | 22.8 / 24.0 / 25.2 V - ensures reliable conduction onset above system operating voltage while accommodating tolerance stack-up |
| VWM | 20.5 V - maximum continuous reverse voltage before significant leakage; compatible with 12 V automotive bus with margin |
| VC @ IPPM | 33.2 V - clamping voltage during 18.1 A 10/1000 μs transient; protects downstream ICs rated ≤36 V |
| PPPM | 600 W - peak pulse power handling capability per standard 10/1000 μs waveform |
| TJ max | +185 °C - enables operation in under-hood automotive environments without derating |
| ESD Rating | ±30 kV (IEC 61000-4-2) - provides robust electrostatic discharge immunity for exposed sensor interfaces |

Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
|
Use Scenario: Protecting analog output lines of wheel speed sensors and pressure transducers from load-dump and inductive kickback in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed between sensor output and microcontroller ADC input. Use Value: Limits transient excursions to ≤33.2 V, preventing damage to 3.3 V or 5 V ADC front-ends while maintaining signal integrity below 20.5 V normal operation. |
Use Scenario: Safeguarding CANH/CANL differential pair in industrial automation gateways exposed to EFT and surge events. IC Role / Device Role / Timing Role: Low-capacitance TVS placed across CAN bus lines to suppress common-mode transients without distorting data signals.

Use Scenario: Front-end protection for 24 V industrial PLC I/O modules subjected to lightning-induced surges on field wiring. IC Role / Device Role / Timing Role: Standoff-rated TVS on power entry point to limit incoming transients before bulk filtering and regulation. Use Value: Withstands repeated 600 W pulses and operates reliably from -65 °C to +185 °C, ensuring uptime in uncontrolled ambient conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-E3/57T | DO-214AC (SMA) package; 24 V unidirectional; 400 W PPPM; higher RθJA (190 °C/W) | Requires external polarity management; less suitable for space-constrained automotive PCBs | Select when legacy SMA footprint compatibility is required and unidirectional protection suffices |
| SMCJ24CA | DO-214AB (SMC) package; 24 V bidirectional; 1500 W PPPM; larger 7.11 mm × 6.22 mm footprint | Better surge handling but incompatible with DFN3820A layout; higher profile limits use in thin modules | Select when higher peak power (1500 W) is mandatory and board space permits larger package |
Compared with SMAJ24A-E3/57T and SMCJ24CA, the T6N24CAHM3/H delivers AEC-Q101 qualification, superior thermal performance (RθJM ≤6.5 °C/W), and compact DFN3820A packaging - making it optimal for next-generation automotive electronics where size, reliability, and manufacturability are co-prioritized.

FAQ
What is the breakdown voltage tolerance of the T6N24CAHM3/H?
The T6N24CAHM3/H has a ±5 % breakdown voltage tolerance, specified as 22.8 V (min) to 25.2 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise system-level overvoltage margining in automotive designs where the T6N24CAHM3/H is deployed.
Is the T6N24CAHM3/H suitable for use in AEC-Q101-compliant automotive modules?
Yes, the T6N24CAHM3/H carries full AEC-Q101 qualification, confirmed by Vishay's documentation (Document Number 98489, Revision 17-Oct-2023). Its 185 °C junction rating, MSL Level 1 reflow compatibility, and halogen-free RoHS-compliant construction make it appropriate for under-hood and ADAS applications where the T6N24CAHM3/H serves as primary transient protection.
Does the T6N24CAHM3/H require polarity-aware PCB layout?
No - the T6N24CAHM3/H is a bidirectional TVS diode with no cathode band marking, as explicitly stated in the Vishay datasheet. Its symmetrical DFN3820A package allows unrestricted orientation during placement, simplifying layout and reducing assembly errors in high-volume automotive manufacturing where the T6N24CAHM3/H is commonly used.
What is the maximum clamping voltage of the T6N24CAHM3/H under surge conditions?
The T6N24CAHM3/H clamps to a maximum of 33.2 V at its rated peak pulse current of 18.1 A (10/1000 μs waveform). This value is measured and guaranteed per Vishay's electrical characteristics table and defines the upper voltage limit imposed on protected circuitry during transient events where the T6N24CAHM3/H activates.
How does the DFN3820A package of the T6N24CAHM3/H support automated optical inspection?
The DFN3820A package of the T6N24CAHM3/H features side-wettable flanks - exposed copper terminations along the package edges - enabling full solder joint inspection using standard AOI systems without requiring X-ray. This design directly supports zero-defect manufacturing goals in automotive electronics where the T6N24CAHM3/H is integrated into safety-critical modules.
