ZP200A Rectifier

ZP200A Rectifier (High‑Power Silicon Rectifier Diode)

ZP200A is an industrial‑grade silicon rectifier diode with a rated average forward current of 200A, belonging to the standard ZP series rectifier diodes. It is widely used in medium‑ and high‑power AC/DC conversion applications, featuring high surge current capability and a fully hermetic structure.

1. Model Explanation

6. Selection & Replacement Solutions

6.1 Key Selection Parameters

電圧マッチング: VRRM ≥ 1.2 × maximum system reverse voltage

(例えば, ≥1200V for 3‑phase 380V systems)

Current Margin: IF(AV) ≥ 1.5 × actual operating current

Package Choice: Stud type for limited space; Plate type (double‑sided cooling) for high power & high heat dissipation

Recovery Characteristic: Standard type for general loads; Fast Recovery Diode (FRD) recommended for high‑frequency applications

6.2 Replacement Options

7. インストール & Safety Guidelines
8. Heat Dissignment

Must use heat sink ≥ 200cm²; forced air cooling (wind speed ≥ 2m/s) recommended

Apply thermal grease for stud types; use specified mounting force (3.3~5.5kN)

2. Wiring Rules

Distinguish anode/cathode on the bolt (usually bolt = cathode, case = anode)

Copper busbar cross‑section ≥ 50mm² to avoid overheating

3. 保護措置

Parallel RC snubber circuit (suppress surge voltage)

Series fast‑acting fuse (IF ≥ 200A, I²t matches 64kA²s)

8. Multilingual Technical Description

9. Purchasing Recommendations
10. Prefer products marked with a complete model (including voltage); reject unlabeled “general ZP200A”
11. For critical applications (elevators, medical equipment), choose branded products (People Electric, Yangjie Tech, 等) to avoid counterfeits
12. For bulk orders, request type test reports (including surge current, thermal resistance, 等)
