概述

Description

P6SMB200AT3G is a high‑power transient-voltage-suppressor (TVS) diode in an SMB (surface-mount) package. It’s part of the P6SMB family and is designed to protect circuits from voltage spikes by clamping transients to safe levels on power rails or data lines. The "200" indicates a ~200 V class stand-off voltage, suitable for higher‑voltage protection applications. It’s a two‑terminal device and typically available in a tape/ reel (T3G) packaging for automated assembly. Use it to safeguard telecom, automotive, industrial, and power‑supply circuits; check the datasheet for exact VRWM, breakdown, clamp voltages, leakage, peak pulse capability, and whether the variant is unidirectional or bidirectional.

Features

Here are the core features of P6SMB200AT3G:
- TVS diode in SMB package (surface-mount, DO-214AA)
- VRWM (standoff voltage) = 200 V
- Peak pulse power: 600 W (8/20 µs)
- Fast response for surge/ESD protection
- Operating temperature range: typically -55 °C to +125 °C
- RoHS compliant and lead-free
- Part of the P6SMB family (available in uni/bidirectional variants as applicable)
- Suitable for protecting power rails and I/O lines in high-voltage/surge environments
Note: exact variant (unidirectional vs. bidirectional) should be confirmed from the datasheet for this specific package/vendor.

Package

P6SMB200AT3G comes in an SMB (DO-214AA) surface-mount, molded-epoxy package (SMB/DO-214AA).

Pinout

Pin count: 2 (two terminals: anode and cathode).
Function: A TVS (transient-voltage-suppression) diode in an SMB package used to clamp and absorb transient over‑voltage events (ESD, lightning, surge) to protect sensitive electronic circuits.

Manufacturer

I can’t verify live part numbers from here. To confirm, please allow me to look it up or check a distributor/datasheet (Mouser, Digi‑Key, Octopart).
Generally, P6SMB200AT3G is the designation of a 200 V SMB‑package TVS (transient‑voltage‑suppressor) diode; the manufacturer will be a semiconductor/components company that makes discrete protection devices (e.g., companies like Diodes Incorporated, Littelfuse, Bourns, ProTek, or Micro Commercial Components). Check the distributor listing or the official datasheet to see the exact manufacturer and company profile.

Application

P6SMB200AT3G is a 600W peak‑pulse TVS diode for transient protection on high‑voltage lines. Applications include surge/ESD protection for AC mains inputs and high‑voltage DC rails, power supplies, adapters and chargers, telecom/datacom and industrial control equipment, and automotive/high‑voltage systems.

Equivalent

P6SMB200AT3G is a unidirectional SMB‑package TVS diode (~200 V class). Direct equivalents: SMBJ200A family (Vishay, Littelfuse, Bourns) and other SMB unidirectional 200 V TVS parts. For replacements also consider 1.5KE200A (different power rating). Always verify V_R, V_BR, V_C and I_PP in datasheets for true drop‑in compatibility.
