It operates across –65 °C to +185 °C junction temperature range and is AEC-Q101 qualified for automotive-grade reliability.
For engineers reviewing the TPC39A-6001HM3_A/H datasheet, TPC39A-6001HM3_A/H pinout, TPC39A-6001HM3_A/H application, or TPC39A-6001HM3_A/H equivalent, key selection criteria include unidirectional clamping performance, 1500 W peak pulse power rating, low-profile 1.1 mm height, MSL Level 1 moisture sensitivity, and halogen-free RoHS-compliant construction.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for fast response time and low incremental surge resistance. Its unidirectional architecture provides robust protection against inductive switching transients and lightning-induced surges on power rails and signal lines.
The device is rated for 10/1000 μs waveform testing per IEC 61000-4-5 and meets JESD201 Class 2 whisker resistance. Its TJ = 185 °C capability supports high-reliability operation in under-hood automotive environments and industrial control systems with elevated ambient temperatures.

FAQ
What is the clamping voltage of the TPC39A-6001HM3_A/H at its rated peak pulse current?
The TPC39A-6001HM3_A/H has a maximum clamping voltage (VC) of 53.9 V at its rated peak pulse current (IPPM) of 27.8 A under 10/1000 μs waveform conditions. This value is measured per IEC 61000-4-5 and ensures downstream components rated for ≤60 V operation remain protected during surge events. The TPC39A-6001HM3_A/H maintains this clamping performance across its full operating temperature range.
Is the TPC39A-6001HM3_A/H suitable for automotive applications?
Yes, the TPC39A-6001HM3_A/H is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and powertrain applications including engine control units, battery management systems, and ADAS power supplies. Its TO-277A package and HM3 suffix confirm halogen-free, RoHS-compliant, and whisker-resistant construction per automotive manufacturing standards. The TPC39A-6001HM3_A/H meets these requirements without derating.
What is the stand-off voltage (VWM) of the TPC39A-6001HM3_A/H and how does it relate to system design?
The TPC39A-6001HM3_A/H has a stand-off voltage (VWM) of 33.3 V, meaning it remains non-conductive below this voltage with leakage <1 μA at 25 °C. This allows integration into 36 V nominal systems - such as 12 V/24 V/36 V automotive buses - without false triggering during normal operation. Designers must ensure VWM exceeds maximum steady-state rail voltage by ≥10 %, which the TPC39A-6001HM3_A/H satisfies for 33 V rails.
Does the TPC39A-6001HM3_A/H have a bidirectional configuration option?
No, the TPC39A-6001HM3_A/H is unidirectional only, as confirmed in the Vishay datasheet under FEATURES and PRIMARY CHARACTERISTICS. It is designed for DC power rail and single-polarity signal line protection. For AC or bidirectional signal protection, designers must select a different family - e.g., the bidirectional SMAJxxCA series - as the TPC39A-6001HM3_A/H lacks symmetrical breakdown characteristics and cannot clamp negative transients.
What is the moisture sensitivity level (MSL) rating for the TPC39A-6001HM3_A/H?
The TPC39A-6001HM3_A/H is rated MSL Level 1 per J-STD-020, indicating unlimited floor life at ≤30 °C/60 % RH and no baking requirement prior to reflow soldering. This simplifies manufacturing logistics and eliminates moisture-related popcorning risk during assembly. The MSL Level 1 classification applies to the TO-277A (SMPC) package used in the TPC39A-6001HM3_A/H and is verified in the Vishay document 89056.
