Overview
The S6040R is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse Inc. It features a single element configuration housed in a TO-263AB (D2PAK-3) plastic package with an isolated case connection. The device supports a maximum repetitive peak off-state voltage of 600 V and a root-mean-square on-state current rating of 40 A. It operates within a junction temperature range of -40 °C to 125 °C. The component is RoHS compliant and utilizes lead-free soldering processes compatible with surface mount assembly standards.
Feature Summary
- Sensitive gate design allows for direct interfacing with microprocessors using minimal gate current.
- Glass passivated junction construction ensures durability against environmental stress.
- Surface mount D2PAK package facilitates automated placement and high-density PCB layouts.
Applications
- Capacitive-discharge ignition systems
- Fluid level sensors
- Strobe light circuits
Procurement Notes
Verify the specific suffix code on the ordering information to confirm the exact tape-and-reel quantity and shipping configuration. Confirm that the procurement documentation explicitly states RoHS compliance and lead-free status to ensure adherence to environmental regulations. Cross-reference the manufacturer's latest datasheet revision to validate the electrical parameters before finalizing the purchase order.
Selection Notes
Select this component when a high-current surface mount SCR is required for compact designs. Ensure the circuit's peak repetitive voltage does not exceed 600 V and the continuous load current remains within the 40 A RMS limit. Verify that the application can accommodate the thermal requirements associated with the TO-263AB package during operation.
Part Context
This device belongs to Littelfuse's discrete silicon-controlled rectifier portfolio, designed for efficient switching in low-current control circuits. It complements the company's broader range of power control solutions, offering a balance of high current handling and compact surface mount packaging for modern electronic assemblies.
Replacement Considerations
Consult Littelfuse official substitution guides for verified equivalents. Do not assume mechanical or electrical compatibility with generic SCRs from other manufacturers without verifying pinout, voltage ratings, and thermal characteristics.
