Bridge Rectifier datasheet and documents for MSB30M
Bridge Rectifier Overview
The MDD MSB30M is a single-phase glass-passivated bridge rectifier in the UMSB series, designed for surface-mount applications. It features a molded plastic body with four pins and supports a maximum repetitive peak reverse voltage of 1000V and an average forward output rectified current of 3.0A at 30°C case temperature. The device withstands a peak forward surge current of 80A under JEDEC testing conditions. Operating junction temperatures range from -55°C to +150°C. The component is supplied in tape and reel packaging containing 3000 pieces per reel.
Bridge Rectifier Feature Summary
- Glass passivated chip junction construction
- High surge current capability

Bridge Rectifier Procurement Notes
Verify the original part number matches MDD MSB30M and confirm the specification sheet revision A0. Ensure the package code indicates tape and reel delivery with 3000 pieces per reel. Check RoHS compliance status and confirm the manufacturer's marking on the case reads MSB30M. Validate thermal resistance parameters against specific PCB mounting requirements.
Bridge Rectifier Selection Notes
Select this component when a 1000V reverse voltage rating and 3.0A continuous current are required for surface-mount designs. Consider the -55°C to +150°C operating temperature range for high-temperature environments. Evaluate the 80A surge current capacity against potential inrush loads. Confirm compatibility with lead-free soldering profiles requiring peak temperatures above 245°C.
Bridge Rectifier Part Context
This component belongs to the UMSB series of SMD single-phase glass-passivated bridge rectifiers manufactured by MDD. The series includes variants with different voltage ratings such as UMSB30D000S320 and UMSB30G000S340. The MSB30M type specifically corresponds to the 1000V rating within this product family.
