Product details
Overview
VS-ST280CH04C0 from Vishay Semiconductors is a phase control thyristor (SCR) in A-PUK (TO-200AB) metal-ceramic hockey-puck package, rated for 500 A average on-state current, 400 V repetitive peak off-state voltage (VDRM/VRRM), and 1.35 V maximum on-state voltage at 1000 A. It features center-amplifying gate structure and operates across -40 °C to +150 °C junction temperature, serving as main power switching element in high-current AC/DC phase-controlled systems.
For engineers reviewing the VS-ST280CH04C0 datasheet, VS-ST280CH04C0 pinout, VS-ST280CH04C0 application, or VS-ST280CH04C0 equivalent, key selection criteria include its 7200 A non-repetitive surge rating at 50 Hz, 100 μs typical turn-off time, 1000 A/μs dI/dt capability, and thermal resistance of 0.08 K/W under double-side cooling - critical for industrial motor drive and regulated power supply design.
Technical Context
This single SCR device uses a center-amplifying gate structure to ensure reliable triggering under high dV/dt conditions up to 500 V/μs and supports sinusoidal conduction angles from 30° to 180°. Its metal case with ceramic insulator enables direct heatsink mounting and meets international A-PUK (TO-200AB) mechanical standard.
Designed for forced-commutated or line-commutated operation, it delivers 1.35 V VTM at 1000 A and maintains latching current as low as 300 mA (typical) at 150 °C, while sustaining 75 mA peak reverse leakage at maximum junction temperature - enabling stable performance in high-temperature industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(AV) | 500 A average on-state current at 80 °C heatsink temperature - defines continuous DC or half-wave AC load handling capacity |
| VDRM / VRRM | 400 V maximum repetitive peak off-state voltage - sets maximum AC line voltage compatibility for 230 VAC systems |
| VTM | 1.35 V max on-state voltage at 1000 A, 150 °C - determines conduction loss and thermal dissipation in high-current paths |
| tq | 100 μs typical turn-off time - constrains minimum commutation interval and maximum operating frequency in phase-control circuits |
| dI/dt | 1000 A/μs maximum non-repetitive rate of rise of turned-on current - requires gate drive design to avoid false triggering during fast current transients |
| RthJ-hs | 0.08 K/W junction-to-heatsink thermal resistance (double-side cooled) - enables compact thermal management in high-power enclosures |
| IGT | 90 mA max DC gate trigger current at 25 °C - defines minimum gate driver output capability required for reliable turn-on |
Pinout & Package
VS-ST280CH04C0 uses the A-PUK (TO-200AB) metal-ceramic hockey-puck package with three terminals: anode (A), cathode (C), and gate (G). Mounting force is 4900 N (±10%), and the case provides creepage distance ≥7.62 mm and strike distance ≥7.12 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Main current entry terminal | Carries full load current into device; must be electrically isolated from heatsink unless specified otherwise |
| Cathode (C) | Main current exit terminal | Completes main conduction path; auxiliary cathode lead is unsoldered (eyelet terminal per ordering code "0") |
| Gate (G) | Control input for turn-on | Receives pulse-trigger signal; center-amplifying structure ensures robust triggering even under high dV/dt stress |
Key Features
| Feature | Design Value |

FAQ
What is the maximum allowable heatsink temperature for VS-ST280CH04C0 at 500 A IT(AV) with double-side cooling?
The maximum allowable heatsink temperature for VS-ST280CH04C0 at 500 A average on-state current with double-side cooling is 80 °C, as specified in the Absolute Maximum Ratings table. This limit assumes DC or 180° conduction and accounts for the device's 0.08 K/W junction-to-heatsink thermal resistance. Exceeding this temperature risks exceeding the +150 °C maximum junction temperature, potentially triggering thermal runaway or premature failure. Derating is required for lower conduction angles or single-side cooling configurations.
Does VS-ST280CH04C0 support gate triggering at elevated junction temperatures?
Yes, VS-ST280CH04C0 supports gate triggering across its full operating junction temperature range of -40 °C to +150 °C. At 150 °C, the maximum required DC gate trigger current (IGT) drops to 30 mA, and the maximum gate trigger voltage (VGT) reduces to 1.0 V - indicating improved gate sensitivity at high temperature. This behavior is inherent to the silicon structure and is validated per the Triggering section of the datasheet, ensuring reliable turn-on in high-ambient industrial environments.
What is the meaning of the "04" voltage code in VS-ST280CH04C0?
The "04" voltage code in VS-ST280CH04C0 indicates a maximum repetitive peak off-state voltage (VDRM/VRRM) of 400 V, as defined in the Voltage Ratings table of the datasheet. This code follows Vishay's standardized numbering scheme where the numeric suffix multiplied by 100 gives the VRRM rating. The device also supports 500 V non-repetitive peak voltage (VRSM), making it suitable for 230 VAC line-fed applications with margin for transient overvoltages.
Can VS-ST280CH04C0 be used in inverse-parallel configuration for AC switching?
Yes, VS-ST280CH04C0 is commonly used in inverse-parallel pairs for bidirectional AC phase control applications such as solid-state relays and AC voltage controllers. Each device handles one half-cycle, leveraging its 400 V VDRM rating and 500 V VRSM capability. The A-PUK package's symmetrical construction and isolated terminals simplify mounting on shared heatsinks with appropriate insulation, and its 100 μs tq ensures clean commutation when paired with complementary SCRs or snubber networks.
What is the gate terminal configuration for VS-ST280CH04C0 according to its ordering code?
The final "0" in VS-ST280CH04C0 denotes eyelet terminals with unsoldered gate and auxiliary cathode leads, per the Ordering Information Table. This configuration allows field customization of gate wiring and enables flexible integration into press-fit or bolt-down mounting systems. The gate terminal is designed for pin receptacle mating (1.47 mm diameter), and mechanical mounting force must be applied within ±10% of 4900 N to ensure optimal thermal contact and electrical integrity.
