Overview
The Littelfuse S4004DS2RP is a silicon-controlled rectifier (SCR) from the Teccor Sxx40x series, designed for surface-mount applications. It features a rated average on-state current of 4 A and a maximum repetitive peak off-state voltage of 400 V. The device utilizes a sensing gate structure with a typical gate trigger current of 200 µA, facilitating low-power control circuits. Packaged in an SMTO-263-2 form factor, it supports operation within a junction temperature range extending up to +150°C. This component is engineered for high reliability in power control environments requiring compact footprints.
Feature Summary
- Sensing gate architecture enables reliable triggering with minimal gate drive current requirements.
- Surface-mount SMTO-263-2 package design facilitates automated PCB assembly and space-constrained layouts.
- High thermal stability supports continuous operation at elevated junction temperatures up to +150°C.
Applications
- Solid-state relays
- Industrial motor control systems
- Power supply regulation circuits
Procurement Notes
Verify the complete part number including the suffix RP against official Littelfuse documentation to confirm reel packaging specifications. Ensure compatibility with surface-mount reflow soldering profiles specified in the datasheet. Cross-reference the manufacturer's latest revision history to confirm material compliance and pinout consistency before finalizing procurement orders.
Selection Notes
Select this SCR when a low-gate-current sensing gate is required for efficient driver interface. The 400V rating suits medium-voltage AC switching applications. Verify that the 4A RMS current capacity meets the load requirements. Consider the SMTO-263-2 package dimensions for board space constraints and ensure adequate heatsinking if operating near maximum thermal limits.
Part Context
This component belongs to the Littelfuse Teccor Sxx40x family of thyristors. The series is characterized by robust construction for industrial power control duties. The S4004 designation indicates the specific current and voltage ratings within this broader product line, distinguishing it from higher or lower rated variants in the same package style.
Replacement Considerations
Consult Littelfuse official substitution guides for verified equivalents. Generic replacements may differ in gate sensitivity or thermal characteristics. Validate any alternative part against the original electrical parameters and physical footprint before implementation.
