Product details
Overview
HDS20M-13 from Diodes Incorporated is a 2A, 1000V surface-mount standard recovery bridge rectifier in HDS package, featuring 0.95V forward voltage at 1A, 5μA reverse leakage at 1000V/25°C, and UL recognition (E364304). It serves as a compact AC–DC full-wave rectification solution in offline SMPS and LED driver input stages.
For engineers reviewing the HDS20M-13 datasheet, HDS20M-13 pinout, HDS20M-13 application, or HDS20M-13 equivalent, key selection criteria include peak repetitive reverse voltage (1000V), average output current rating (2A @ TC=88°C), thermal resistance (RθJC = 16°C/W), and RoHS/halogen-free compliance for industrial power supply design.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a monolithic HDS package with glass-passivated junctions. It supports standard recovery operation (trr not specified, consistent with standard recovery classification) and is rated for 700V RMS reverse voltage, requiring 20% current derating under capacitive loads.
Thermal performance is defined by junction-to-case (16°C/W), junction-to-lead (18°C/W), and junction-to-ambient (20°C/W) resistances under standardized PCB mounting conditions. The device operates across –55°C to +150°C and withstands non-repetitive surge currents up to 110A (1ms) and 55A (8.3ms).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse voltage per diode leg; defines safe AC input voltage ceiling in bridge configuration. |
| IO (avg) | 2.0 A @ TC = +88°C - Continuous DC output current capability when case temperature is maintained at 88°C. |
| VF | 0.95 V @ IF = 1A, TA = +25°C - Forward voltage drop per diode; determines conduction loss in rectifier arms. |
| IR | 5 μA @ VR = 1000V, TA = +25°C - Reverse leakage per diode; impacts standby power and high-impedance hold-off stability. |
| IFSM (1ms) | 110 A - Non-repetitive surge current tolerance; enables robustness against line transients and inrush events. |
| RθJC | 16 °C/W - Junction-to-case thermal resistance; informs heatsinking requirements when mounted on thermally enhanced pads. |
| CT | 13 pF @ VR = 4V, f = 1MHz - Junction capacitance per diode; influences EMI generation and high-frequency switching behavior. |
Pinout & Package
Package: HDS - miniature surface-mount plastic package (UL 94V-0), dimensions 5.05 × 6.6 × 1.25 mm (L × W × H), with matte tin-plated terminals and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Input AC terminal (anode of D1, cathode of D2) | One AC input node of full-wave bridge; connects to live/neutral side of transformer secondary or AC line. |
| AC2 | Input AC terminal (anode of D3, cathode of D4) | Second AC input node; completes differential AC input path for full-wave rectification. |
| + (Anode Common) | Positive DC output (cathodes of D1 & D3) | Rectified positive rail output; routed to bulk capacitor or downstream DC-DC stage. |
| – (Cathode Common) | Negative DC output (anodes of D2 & D4) | Rectified negative/return rail; establishes DC reference for output filter and load return path. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated die construction | Enhances long-term reliability and humidity resistance without hermetic sealing; critical for consumer-grade power supplies operating in variable environments. |
| Low forward voltage (0.95V) | Reduces conduction losses by ~15% vs. typical 1.1V bridges at 1A, improving efficiency in 12–24W LED drivers and adapters. |
| UL Recognized Component (E364304) | Validates safety compliance for end-equipment certification; eliminates need for additional system-level isolation testing in Class II designs. |
| Lead-free, halogen- and antimony-free "Green" construction | Meets RoHS 3 (2015/863/EU) and JEDEC J-STD-020 Level 1 moisture sensitivity; enables direct SMT reflow without baking. |
Applications
| LED Lighting Drivers | AC-DC Adapters |
|---|---|

IC Role / Device Role / Timing Role: Full-wave bridge feeding parallel PFC and main converter inputs in compact multi-output designs. Use Value: 2A IO rating supports combined 30W+ output; low IR (<5μA) prevents capacitor discharge during no-load standby. | Use Scenario: AC input rectification in internal power supplies for printers, scanners, and multifunction devices. IC Role / Device Role / Timing Role: Standard recovery bridge supplying bulk DC to multiple DC-DC rails (24V, 12V, 5V, 3.3V). Use Value: RθJC = 16°C/W enables thermal management via copper pour on inner layers; RoHS/Green compliance meets global OEM procurement mandates. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K (ON Semiconductor) | Same 1000V/2A rating but in GBU package (10.3 × 14.2 × 3.5 mm); VF = 1.1V @ 1A; higher RθJA (30°C/W). | Larger footprint; requires more PCB area and heatsinking; suited for through-hole legacy upgrades. | Select when retrofitting existing GBU footprints or where higher surge rating (IFSM = 150A) is prioritized over size. |
| MB2S (Vishay) | Smaller MB-S package (4.8 × 6.2 × 1.3 mm); same 1000V/2A; VF = 1.05V; IR = 10μA @ 1000V/25°C. | Higher leakage limits use in ultra-low-standby applications; slightly larger VF increases conduction loss. | Prefer for space-constrained designs where 5μA IR is not mandatory and 0.1V VF penalty is acceptable. |
Compared with GBU2K and MB2S, the HDS20M-13 delivers the lowest forward voltage (0.95V) and tightest leakage (5μA) in the smallest surface-mount form factor, making it optimal for high-density, efficiency-critical AC-DC front ends.

FAQ
What is the maximum allowable case temperature for continuous operation?
The HDS20M-13 is rated for 2.0A average output current at TC = +88°C. Exceeding this temperature requires linear derating per the datasheet's thermal curves. At TC = +125°C, the current rating drops to approximately 1.2A. Thermal design must ensure the case (measured at the center of the package bottom) remains within this limit under worst-case ambient and airflow conditions.
Is the HDS20M-13 suitable for use in automotive applications?
The HDS20M-13 is not AEC-Q200 qualified and is not intended for automotive use. Diodes Incorporated explicitly states that automotive-grade parts require specific change control, PPAP capability, and IATF 16949 manufacturing-none of which apply to this standard commercial-grade rectifier. For automotive applications, consult Diodes' AEC-Q200-certified bridge rectifiers such as the DB107S-A or DB207S-A series.
How does the HDS package compare to SMB or GBU in terms of thermal performance?
The HDS package offers RθJC = 16°C/W, significantly better than SMB (≈25°C/W) and comparable to GBU (≈15°C/W), despite its smaller footprint. This is achieved via optimized leadframe thermal paths and direct junction-to-lead conduction. However, RθJA = 20°C/W assumes a 30mm×30mm 1oz copper pad per pin-performance degrades sharply with reduced copper area.
Does the HDS20M-13 have a specified reverse recovery time (trr)?
No, the HDS20M-13 datasheet does not specify reverse recovery time (trr), confirming its classification as a standard (not fast or ultrafast) recovery rectifier. Its internal construction and electrical characteristics-including VF and IR-are optimized for 50/60Hz line-frequency rectification, not high-frequency switching. Use in circuits above 20kHz requires empirical validation of switching loss and EMI behavior.
