Descripción general

Description

P6SMB39AT3G is a high‑power transient-voltage-suppression (TVS) diode in an SMB package. It’s part of the P6SMB family (600 W peak pulse power, 8/20 μs) and is the unidirectional variant (A). Its working standoff voltage is about 39 V (VRWM), making it suitable for protecting 24 V rails and similar lines from voltage transients, surges, or ESD. The “T3G” suffix typically relates to packaging/labeling (e.g., tape‑and‑reel, RoHS/compliant) and does not change the electrical behavior. Use it to clamp harmful impulses on power or signal lines in automotive, industrial, or telecom applications.

Features

Here are the main features of P6SMB39AT3G:
- 600 W peak pulse power capability (8/20 µs)
- Unidirectional transient voltage suppressor (TVS) diode
- Working stand-off voltage (VRWM) = 39 V
- SMB (DO-214AB) package; tape & reel (T3G), RoHS-compliant/halogen-free
- Wide operating temperature range (-55 °C to +150 °C)
- Very fast response time with low leakage in normal operation
- Suitable for protecting 39 V power/signal lines from voltage transients
Note: Specific clamping voltage and leakage vary with conditions; refer to the datasheet for exact curves.

Package

P6SMB39AT3G is packaged in an SMB (DO-214AA) surface-mount package and supplied on tape-and-reel (T3G) for automated assembly.

Pinout

Pin count: 2 pins (anode and cathode) in an SMB/DO‑214AA package.
Function: P6SMB39AT3G is a unidirectional TVS (transient-voltage-suppression) diode for surge and ESD protection. It clamps and shunts transient overvoltage spikes (peak pulse power rating ~600 W typical for the P6SMB family), with a nominal breakdown level indicated by "39" (≈39 V).

Manufacturer

Manufacturer: Diodes Incorporated.
What kind of company: Diodes Inc. is a global semiconductor manufacturer and supplier that designs and produces discrete, analog and mixed-signal semiconductor components (including diodes, TVS diodes, transistors, MOSFETs, logic and power-management devices).

Application

P6SMB39AT3G is a unidirectional TVS diode (SMB package) with about 39 V stand-off and ~600 W peak pulse power. It protects DC rails and data lines from transient surges and ESD. Typical applications: automotive/industrial 12–24 V systems, telecom/network equipment, power supplies, USB/Ethernet/RS-485 interfaces, and general protection of sensitive electronics.

Equivalent

Equivalent parts are any 39V SMB‑package TVS diodes with the same polarity and power rating. Common cross‑references:
- SMBJ39A (Vishay / Littelfuse / ST)
- SM6T39A (Diodes Inc. / Rohm)
- SMB39CA / SMB39A variants from Bourns, ProTek, ON Semiconductor
Verify standoff voltage (39V), unidirectional vs bidirectional, peak pulse power and clamping specs before substituting.
