Key Features
- 200 V blocking voltage and 8 A continuous forward current in a dual common-cathode configuration for full-wave rectification
- Ultra-low forward voltage of 0.89 V max reduces conduction losses and improves rectifier efficiency in SMPS designs
- TO-262 (I²Pak) through-hole package with long leads provides direct heatsink mounting and robust thermal path
- Silicon rectifier technology optimized for high-efficiency applications including PFC stages and secondary rectification
Applications
The STTH1002CR is ideal for secondary-side rectification in switch-mode power supplies, UPS systems, and battery chargers where low forward voltage drop directly improves conversion efficiency. Its common-cathode dual configuration simplifies full-wave rectifier and center-tap circuit layouts. The TO-262 package allows mounting to a heatsink, supporting continuous 8 A operation across a wide ambient temperature range.

Frequently Asked Questions
What are the key electrical ratings of the STTH1002CR for use in a full-wave rectifier bridge?
The STTH1002CR is rated for 200 V repetitive peak reverse voltage and 8 A average forward current in a common-cathode dual configuration. Its maximum forward voltage of 0.89 V at 8 A keeps conduction losses low, making it efficient in 100 V to 200 V AC input rectifier stages.
How does the common-cathode configuration of STTH1002CR simplify center-tap rectifier designs?
With both anodes accessible and cathodes tied together internally, STTH1002CR maps directly to a center-tap transformer secondary without extra wiring. This reduces PCB trace complexity and the two 8 A diodes share a single TO-262 package, cutting component count by half compared to discrete 1-diode solutions.
What thermal advantage does the TO-262 (I²Pak) through-hole package provide for STTH1002CR at full 8 A load?
The TO-262 package features a metal tab that bolts directly to a heatsink, achieving junction-to-case thermal resistance below 5°C/W. This allows the STTH1002CR to dissipate sufficient power at 8 A continuous operation and maintain junction temperature within the rated -40°C to 150°C range even at elevated ambient temperatures.
When would STTH1002CR be preferred over a Schottky rectifier in an SMPS secondary?
STTH1002CR suits applications where the output voltage exceeds 50 V, since Schottky rectifiers with comparable 200 V ratings typically show higher forward voltage than silicon types at elevated temperatures. For 100 V to 200 V output rails at 8 A, the STTH1002CR offers a better cost-to-performance trade-off with its 0.89 V forward drop.
