ZP500A Thyristor (SCR) Control Tube, 200–2000 V — High‑Voltage Gate Trigger Device (Pack of 2)

ZP500A Thyristor (SCR) Control Tube — 200–2000 V — Pack of 2

Overview

• Part number: ZP500A
• Device type: Thyristor / Silicon Controlled Rectifier (SCR) control tube — gate trigger device
• Rated voltage indication: 200–2000 V (as specified)
• Pack quantity: 2 pieces
• Primary use: Gate triggering and control in high‑voltage power‑electronic circuits and trigger modules

Key features

• ZP500A control tube designed for reliable SCR/gate triggering in medium‑to‑high voltage applications.
• Specified nominal operating voltage range: 200–2000 V (use manufacturer specifications for exact operating limits and derating).
• Supplied as a pack of 2 for spare, repair or prototype use.
• Compact form suitable for integration in trigger boards, driver modules and legacy control tube sockets.

Typical applications

• Gate/trigger elements for power thyristor networks and controlled rectifiers.
• Trigger modules for inverters, thyristor converters and industrial power controllers.
• Pulse and timing trigger circuits in heavy‑duty power electronics.
• Laboratory, repair and prototyping use where discrete high‑voltage trigger tubes are required.

Handling, installation & safety notes

• Handle using ESD‑safe procedures to protect gate and junction.
• Confirm mechanical package, pinout and socket compatibility before installation — datasheet or manufacturer drawing required for exact pin assignments.
• Verify gate drive requirements, expected load currents and thermal dissipation with the original manufacturer specification prior to use. Provide adequate heat sinking and thermal management if applicable.
• Do not assume ratings beyond the stated voltage range; consult the manufacturer for peak repetitive voltages, surge capabilities and maximum continuous current.
