Product details
Overview
T6N56CAHM3/I from Vishay General Semiconductor is a bidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 56 V nominal breakdown voltage (±5 %), 47.8 V stand-off voltage, 77.0 V maximum clamping voltage at 7.8 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 line protection against inductive switching transients and ESD.
For engineers reviewing the T6N56CAHM3/I datasheet, T6N56CAHM3/I pinout, T6N56CAHM3/I application, or T6N56CAHM3/I equivalent, key selection criteria include clamping performance under 10/1000 μs surge, bidirectional polarity, MSL Level 1 reflow compatibility, side-wettable flanks for AOI, and AEC-Q101 qualification for automotive ECUs and ADAS sensor interfaces.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to achieve stable breakdown behavior and low leakage (<1 μA at VWM, <1 μA at TJ = 150 °C). Its DFN3820A package enables high thermal resistance performance (RθJM = 5–6.5 °C/W) and supports automated placement with solderable matte tin terminals meeting J-STD-002 and JESD 22-B102.
It delivers 30 kV IEC 61000-4-2 contact/air discharge immunity and operates across -65 °C to +185 °C junction temperature range. The device is optimized for transient suppression on bidirectional signal lines where low capacitance and fast response are required - confirmed by typical junction capacitance curves referenced at 1 MHz and zero bias.
Key Specifications

IC Role / Device Role / Timing Role: Standoff-rated TVS (VWM = 47.8 V) placed between LIN bus and transceiver, compatible with 12 V system nominal voltage. Use Value: Maintains <1 μA leakage at VWM, preventing false wake-up or communication errors during sleep mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58A-E3/5A (Vishay) | DO-214AC package, unidirectional, 58 V VBR, 600 W PPPM, higher profile (2.3 mm), no AEC-Q101 grade | Requires polarity-aware layout; unsuitable for bidirectional AC signals or space-constrained automotive PCBs | Select only if unidirectional clamping suffices and board height budget allows DO-214AC footprint |
| TPSMF58A (STMicroelectronics) | DFN2510-10 package, unidirectional, 58 V VBR, 600 W PPPM, AEC-Q101 qualified, but no side-wettable flanks | Lacks AOI-compatible terminals; requires X-ray or manual inspection for solder joint validation in automotive production | Acceptable for non-AOI production lines or cost-sensitive industrial designs where AOI is not mandated |
Compared with SMAJ58A-E3/5A and TPSMF58A, the T6N56CAHM3/I uniquely combines bidirectional operation, AEC-Q101 qualification, side-wettable flanks, and DFN3820A's ultra-low 0.88 mm height - making it the only option qualified for high-reliability automotive signal line protection with full process traceability.

FAQ
What is the breakdown voltage tolerance of the T6N56CAHM3/I?
The T6N56CAHM3/I has a breakdown voltage tolerance of ±5 %, with a nominal VBR of 56 V (min 53.2 V, max 58.8 V) measured at 1 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margining in automotive safety-critical circuits. The T6N56CAHM3/I maintains this specification across its full operating temperature range.
Is the T6N56CAHM3/I suitable for bidirectional signal lines like CAN or LIN?
Yes, the T6N56CAHM3/I is explicitly designed as a bidirectional TVS diode with no cathode marking, making it suitable for protecting differential or AC-coupled signal lines including LIN bus and sensor interfaces. Its symmetrical clamping characteristic ensures equal protection for positive and negative transients - a requirement confirmed in the "Polarity: Bidirectional" specification and verified in the electrical characteristics table for the T6N56CAHM3/I.
Does the T6N56CAHM3/I meet AEC-Q101 requirements?
Yes, the T6N56CAHM3/I is AEC-Q101 qualified, as indicated by the "H" in the ordering code and explicitly stated in the datasheet's FEATURES section. This qualification covers stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22-A114, confirming suitability for automotive powertrain and chassis applications. The T6N56CAHM3/I carries the HM3 suffix denoting halogen-free, RoHS-compliant, and whisker-tested construction.
What is the maximum clamping voltage of the T6N56CAHM3/I under surge conditions?
The T6N56CAHM3/I has a maximum clamping voltage (VC) of 77.0 V at 7.8 A peak pulse current (IPPM) under the standardized 10/1000 μs waveform. This value is measured and guaranteed per the datasheet's ELECTRICAL CHARACTERISTICS table and defines the upper voltage limit imposed on protected circuitry during worst-case transients. The T6N56CAHM3/I maintains this clamping performance across its full temperature range.
Can the T6N56CAHM3/I be used in lead-free reflow processes?
Yes, the T6N56CAHM3/I is rated for lead-free reflow with a maximum peak temperature of 260 °C and meets MSL Level 1 per J-STD-020 - meaning it has unlimited floor life and requires no dry-pack storage or baking prior to assembly. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, ensuring reliable solder wetting in standard SMT processes. This applies directly to the T6N56CAHM3/I manufacturing specification.
