Product details
Overview
T6N24CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 24 V nominal breakdown voltage (VBR = 22.8–25.2 V), 20.5 V stand-off voltage (VWM), and 600 W peak pulse power (10/1000 μs). It delivers 18.1 A peak pulse current and clamps to 33.2 V at rated surge, supporting automotive-grade ESD protection (30 kV contact/air) in sensor signal lines and MOSFET gate circuits.
For engineers reviewing the T6N24CAHM3/I datasheet, T6N24CAHM3/I pinout, T6N24CAHM3/I application, or T6N24CAHM3/I equivalent, this device serves as an AEC-Q101-qualified, halogen-free, RoHS-compliant TVS for high-reliability automotive electronics requiring TJ = 185 °C operation, side-wettable flanks for AOI, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
This TVS employs passivated anisotropic rectifier technology optimized for junction stability under thermal stress, enabling continuous operation up to +185 °C junction temperature. Its bidirectional clamping architecture provides symmetrical transient suppression without polarity dependency, making it suitable for AC-coupled or differential signal paths.
The DFN3820A package features leadless construction with side-wettable flanks-designed specifically for automated optical inspection and high-yield SMT placement. Thermal resistance is characterized per JEDEC 51-2A (RθJA ≤ 175 °C/W) and JEDEC 51-14 (RθJM ≤ 6.5 °C/W), confirming efficient heat transfer to PCB mount pads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24AHE3/5AT | DO-214AC (SMA) package, 24 V unidirectional, 400 W PPPM, higher RθJA (190 °C/W) | Requires polarity-aware layout; unsuitable for AC-coupled signals without external diode pairing | Select when legacy SMA footprint reuse is required and bidirectionality is not needed |
| SMCJ24CA | DO-214AB (SMC) package, 24 V bidirectional, 1500 W PPPM, 2.4 mm height, no side-wettable flanks | Larger footprint and height limit placement near connectors; AOI requires custom vision setup | Select when higher surge rating is critical and space constraints allow larger package |
Compared with SMAJ24AHE3/5AT and SMCJ24CA, the T6N24CAHM3/I offers superior board-area efficiency, built-in AOI support, and tighter thermal resistance-making it optimal for next-generation automotive modules where miniaturization, process automation, and under-hood reliability are prioritized.

FAQ
What is the maximum clamping voltage of the T6N24CAHM3/I at its rated peak pulse current?
The T6N24CAHM3/I exhibits a maximum clamping voltage (VC) of 33.2 V when subjected to its rated peak pulse current (IPPM) of 18.1 A under the standard 10/1000 μs waveform. This value is measured per IEC 61000-4-5 and ensures downstream components remain within safe voltage margins during surge events. The T6N24CAHM3/I maintains this clamping performance across its full operating temperature range up to +185 °C junction temperature.
Is the T6N24CAHM3/I suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the T6N24CAHM3/I is explicitly AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HM3" and documentation in datasheet 98489. It undergoes rigorous stress testing-including high-temperature reverse bias (HTRB), temperature cycling, and ESD-per AEC-Q101 standards. The T6N24CAHM3/I is designed for under-hood and body-control module deployments where reliability at TJ = 185 °C is mandatory.
What does the "HM3" suffix in T6N24CAHM3/I indicate?
The "HM3" suffix in T6N24CAHM3/I denotes three key attributes: "H" indicates AEC-Q101 qualification; "M3" specifies halogen-free, RoHS-compliant, and Pb-free termination meeting J-STD-609 Class 1 requirements. The "I" denotes 13-inch tape-and-reel packaging with 14,000 units per reel. This suffix confirms the T6N24CAHM3/I meets automotive material, reliability, and logistics specifications out-of-box.
Does the T6N24CAHM3/I require a specific PCB pad layout for optimal thermal performance?
Yes, the T6N24CAHM3/I requires adherence to the DFN3820A mounting pad layout specified in Vishay's datasheet 98489 (page 5), including recommended copper area and thermal vias beneath the exposed pad. Deviation reduces thermal resistance (RθJM) and risks exceeding the 185 °C maximum junction temperature during repeated surge events. The T6N24CAHM3/I's RθJM ≤ 6.5 °C/W assumes strict compliance with this layout.
Can the T6N24CAHM3/I be used in bidirectional signal lines such as RS-485 or CAN bus?
Yes, the T6N24CAHM3/I is inherently bidirectional with no polarity marking, making it ideal for protecting differential communication buses like CAN FD and RS-485. Its low clamping voltage (33.2 V), fast response, and <100 pF junction capacitance at 0 V ensure minimal signal distortion. The T6N24CAHM3/I is commonly deployed across both lines of such interfaces without additional circuitry or orientation concerns.
