Diodes Incorporated HS1DDF-13

Overview

HS1DDF-13 from Diodes Incorporated is a 1.0A, 200V hyper-fast recovery surface-mount rectifier in D-FLAT package, optimized for boost diode roles in PFC circuits and secondary/freewheeling rectification in high-frequency AC-DC/DC-DC converters operating up to +150°C ambient. Confirmed parameters: V_RRM = 200 V, I_O = 1.0 A, t_RR = 12–15 ns, V_F = 0.87–1.1 V (I_F = 1 A), I_R = 0.02–5 µA.

For engineers reviewing the HS1DDF-13 datasheet, HS1DDF-13 pinout, HS1DDF-13 application, or HS1DDF-13 equivalent, key selection criteria include ultrafast reverse recovery (12 ns typ), low forward voltage at 1A, thermal resistance (R_θJA = 92 °C/W), and D-FLAT package compatibility with high-density consumer power layouts.

Technical Context

This hyper-fast rectifier employs a planar epitaxial silicon structure with glass passivation to achieve tight control of minority carrier lifetime, enabling sub-15 ns reverse recovery time while maintaining low leakage (<5 µA @ 200 V, 25°C). Its junction-to-terminal thermal resistance of 60 °C/W supports reliable operation at T_J up to +150°C when mounted on standard FR-4 PCBs.

The D-FLAT package features a single-sided copper leadframe with matte tin finish, polarity indicated by cathode band, and UL 94V-0 molded compound. It delivers low profile (max height 1.10 mm) and minimal parasitic capacitance (C_T = 16 pF @ 4 V), critical for EMI-sensitive switching topologies.

Key Specifications

FAQ

What is the maximum junction temperature for HS1DDF-13?

The HS1DDF-13 has an operating junction temperature range of –55°C to +150°C. Its R_θJA = 92 °C/W (on 1"×1", 2 oz FR-4) and R_θJT = 60 °C/W allow safe operation at full 1.0 A load up to +88°C case temperature, verified per JEDEC test conditions.

Is HS1DDF-13 compatible with lead-free reflow soldering?

Yes. The HS1DDF-13 features matte tin-plated copper leadframe and is qualified for lead-free reflow soldering per J-STD-020. Its moisture sensitivity level is MSL 1, eliminating bake requirements prior to assembly.

How does HS1DDF-13 differ from standard fast recovery diodes?

HS1DDF-13 achieves 12–15 ns t_RR-roughly 3× faster than standard fast rectifiers (typically 50–100 ns)-due to controlled carrier lifetime and optimized epitaxial layer design, directly reducing switching loss and EMI in >100 kHz applications.

Can HS1DDF-13 be used in automotive under-hood applications?

No. While rated for T_J up to +150°C, HS1DDF-13 is commercial-grade (AEC-Q101 unqualified) and not specified for automotive under-hood use. Diodes Incorporated offers AEC-Q101-qualified alternatives like the B1100Q series for such applications.
