SM16GZ47, SM16JZ47, SM16GZ47A, SM16JZ47A are Toshiba's bidirectional silicon planar thyristors for AC power control, with features such as 400V, 600V peak repetitive off-voltage, 16A effective on-current, 30mA (general type) or 20mA (high sensitivity type) gate trigger current, 10V/μs (general type) or 4V/μs (high sensitivity type) transition time critical off-voltage rise rate, and 1500V AC 60 seconds insulation resistance.
The SM16GZ47 family are Toshiba bidirectional silicon-controlled rectifiers (SCR) designed for power conversion and current control applications. The series includes standard (SM16GZ47, SM16JZ47) and high‑sensitivity (SM16GZ47A, SM16JZ47A) types, each UL‑certified for reliable operation.
The document provides detailed electrical parameters such as peak repetitive off‑voltage, gate trigger currents, on‑state RMS current, isolation voltage, and temperature limits, as well as characteristic curves for gate and drain triggering. Safety notes and usage restrictions for critical applications are also included. This manual is written in Japanese.
| Peak repetitive off‑voltage (VDRM) | 400 V / 600 V |
|---|---|
| Effective on‑current (RMS) IT(RMS) | 16 A |
| Gate trigger current (Ig m) – standard type | 90 mA MAX |
| Gate trigger current (Ig m) – high‑sensitivity type | 20 mA MAX |
| Isolation voltage (AC 60 s) | 1500 V |
| Operating temperature range | -40 °C to 125 °C |
The peak repetitive off‑voltage (VDRM) is specified as 400 V or 600 V depending on the model.
The devices are rated for an isolation voltage of 1500 V AC for 60 seconds.
They can be operated from –40 °C up to 125 °C.
