Diodes Incorporated DHDS2100-13

Overview

DHDS2100-13 from Diodes Incorporated is a 2A, 100V peak repetitive reverse voltage Schottky bridge rectifier in HDS package, featuring 0.85V max forward voltage at 2A and 50µA max reverse leakage at 100V/25°C, optimized for compact AC/DC front-end rectification in energy-saving lamps and mobile battery chargers.

For engineers reviewing the DHDS2100-13 datasheet, DHDS2100-13 pinout, DHDS2100-13 application, or DHDS2100-13 equivalent, key selection criteria include low VF for efficiency, PRV margin for surge robustness, thermal resistance (RθJA = 75°C/W), and RoHS-compliant lead-free plating for PCB assembly compatibility.

Technical Context

This monolithic Schottky bridge integrates four diodes in a single HDS surface-mount package to deliver full-wave rectification without external interconnects. It operates with junction temperatures from –55°C to +150°C and supports 50A non-repetitive surge current (8.3ms half-sine) under rated load conditions.

The device uses green molding compound (UL 94V-0), matte tin terminal plating, and exhibits 75pF typical junction capacitance at 4V/1MHz - enabling stable high-frequency switching behavior in compact power supplies where layout parasitics must be minimized.

Manufacturer

Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design, manufacturing, and sales operations across Asia, Europe, and North America.

The HDS Schottky bridge product line targets cost-sensitive, space-constrained AC/DC conversion applications where low VF, high reliability, and RoHS/Green compliance are mandatory design requirements.

FAQ

What is the maximum allowable junction temperature for DHDS2100-13?

The DHDS2100-13 has a specified operating junction temperature range of –55°C to +150°C. Its absolute maximum TJ is +150°C; sustained operation above this limit risks irreversible degradation of the Schottky junction and packaging integrity. Derating curves in Figure 1 confirm stable forward characteristics up to 150°C.

Can DHDS2100-13 replace a discrete 4-diode bridge in existing designs?

Yes - DHDS2100-13 provides identical full-wave rectification functionality in a single HDS package. Pin-compatible replacement requires verifying PCB pad layout matches the HDS outline (D1 = 0.45–0.85 mm, E1 = 6.40–6.80 mm), and confirming thermal relief design accommodates its 75°C/W RθJA on standard FR-4.

Is DHDS2100-13 qualified for automotive applications?

No - DHDS2100-13 is not AEC-Q101 qualified. The datasheet explicitly states that automotive-grade parts require separate qualification (AEC-Q100/101/104/200), PPAP capability, and IATF 16949 manufacturing - none of which apply to this standard commercial-grade Schottky bridge.

How does the NC terminal affect PCB layout?

The NC (no-connect) terminal is a mechanical pad with no internal bond wire or silicon connection. It must remain unconnected in layout and routing; soldering or grounding it may cause mechanical stress or unintended thermal paths. The datasheet specifies "NC" in the pin diagram and warns against electrical use.
