Diodes Incorporated DHDS1100-13

Overview

DHDS1100-13 from Diodes Incorporated is a 1A, 100V peak repetitive reverse voltage Schottky bridge rectifier in HDS surface-mount package, featuring 0.85V max forward voltage at 1A and 10µA max reverse leakage at 100V/25°C, used for AC-to-DC conversion in compact energy-saving lamps and mobile battery chargers.

For engineers reviewing the DHDS1100-13 datasheet, DHDS1100-13 pinout, DHDS1100-13 application, or DHDS1100-13 equivalent, key selection criteria include low VF for efficiency-critical 1A bridge rectification, thermal resistance (RθJA = 75°C/W), RoHS-compliant lead-free plating, and HDS package compatibility with high-density PCB layouts.

Technical Context

This monolithic Schottky bridge integrates four diodes in a single HDS package to provide full-wave rectification without external interconnects, eliminating layout-induced parasitic inductance and enabling compact AC/DC front-end designs. Its low 0.85V VF at 1A reduces conduction loss versus standard silicon bridges, while 75pF junction capacitance at 5V supports stable operation up to ~10MHz switching frequencies.

The device operates across –55°C to +150°C, with thermal resistance of 13°C/W junction-to-case enabling direct heat transfer to copper pads. It is rated for 30A non-repetitive surge current (8.3ms half-sine) and requires 20% derating for capacitive loads per specification.

FAQ

What is the maximum junction temperature for DHDS1100-13?

The DHDS1100-13 has an operating junction temperature range of –55°C to +150°C. Its thermal resistance junction-to-ambient is 75°C/W on a standard 2mm × 2mm 1oz copper pad, meaning at 1A load and 25°C ambient, junction temperature rises to approximately 100°C-well within safe operating limits.

Is DHDS1100-13 suitable for automotive applications?

DHDS1100-13 is not AEC-Q200 qualified. While it meets RoHS and green material requirements, Diodes specifies that automotive-grade parts require explicit AEC-Q200 qualification, PPAP capability, and IATF 16949 manufacturing-none of which apply to this standard commercial-grade part.

How does the HDS package compare to SMB or SMC in size and thermal performance?

The HDS package measures 5.25mm × 4.45mm × 1.30mm-smaller than SMB (4.6mm × 3.6mm) and significantly smaller than SMC (7.1mm × 6.2mm). Its RθJA of 75°C/W is comparable to SMB but inferior to SMC (≈40°C/W), making HDS optimal for space-constrained, moderate-power designs rather than high-current thermal challenges.

Can DHDS1100-13 replace a discrete 4-diode Schottky array?

Yes-DHDS1100-13 replaces four discrete 1A Schottky diodes in full-wave bridge configuration. It provides matched VF and TJ characteristics across all four elements, eliminates layout asymmetry, reduces solder joint count by 75%, and improves reliability in vibration-prone applications like portable chargers.
