Product details

Overview

SDT10H50P5 from Diodes Incorporated is a 10A, 50V Trench Schottky barrier rectifier in PowerDI5 package, featuring 0.45V max forward voltage at 10A/25°C, 0.30mA max reverse leakage at 50V/125°C, and 150°C junction temperature rating. It serves as a high-efficiency freewheel or output rectifier in compact DC/DC converters and AC/DC adapters.

For engineers reviewing the SDT10H50P5 datasheet, SDT10H50P5 pinout, SDT10H50P5 application, or SDT10H50P5 equivalent, key selection criteria include low VF stability across temperature, soft switching behavior for EMI reduction, thermal resistance to case (3°C/W with heatsink), and RoHS-compliant matte tin terminations suitable for lead-free reflow.

Technical Context

This Schottky rectifier uses trench MOS structure to achieve lower forward voltage and improved high-temperature leakage performance versus planar Schottkys. Its soft recovery minimizes voltage overshoot during turn-off, reducing snubber requirements in flyback and synchronous rectification topologies.

The PowerDI5 package enables 25°C/W R_θJA on 2"×2" aluminum heatsink and 90°C/W on standard FR-4 PCB - critical for space-constrained power stages where thermal management drives reliability and derating curves.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	50 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 36–48V input DC/DC or adapter secondary-side applications.
I_O	10 A - Average rectified current at 25°C ambient; derates to ~6.5A at 70°C per Figure 3, guiding heatsink sizing.
V_F (max)	0.45 V @ 10A, 25°C - Low conduction loss improves efficiency >95% in 12V-output buck converters.
I_R (max)	0.30 mA @ 50V, 125°C - Stable leakage ensures minimal standby power loss in always-on systems.
T_J (max)	+150°C - Enables operation in sealed enclosures or under-hood automotive environments without forced cooling.
R_θJC	3 °C/W - With heatsink mounting, allows ~4W dissipation before reaching 150°C junction limit.

Pinout & Package

Package: PowerDI5 - surface-mount, thermally enhanced 3-pin plastic package with exposed cathode pad; UL 94V-0 rated, 0.093g weight, moisture sensitivity level 3.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Anode	Input terminal for forward current flow; connects to switch node or transformer secondary in flyback/buck topologies.
Pin 2	Cathode (Exposed Pad)	Main current return path and primary thermal interface; must be soldered to large copper pour or heatsink for R_θJC = 3°C/W.
Pin 3	Anode	Second anode connection - paralleled internally with Pin 1 to support 10A total current with low inductance.

Key Features

Feature	Design Value
Low forward voltage drop	0.45V max at 10A/25°C reduces conduction loss by ~30% vs. comparable 60V Schottkys, directly improving light-load efficiency.
Soft, fast switching	No minority-carrier storage; negligible reverse recovery charge (Q_rr ≈ 0) eliminates switching spikes and simplifies EMI filter design.
High-temperature leakage stability	0.30mA IR at 125°C enables reliable operation in enclosed power supplies where ambient exceeds 85°C.
+150°C operating junction	Supports full 10A rating in industrial control cabinets or automotive body electronics without derating below 100°C ambient.

Applications

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schottky rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Vishay VS-10BQ040-M3/45	45V V_RRM, 0.42V V_F @ 10A, 25°C, same PowerDI5 package	Lower voltage rating limits use to ≤36V systems; tighter V_F tolerance benefits precision efficiency targets	Select when 45V blocking suffices and sub-0.42V consistency is required across production lots
ON Semiconductor SB1050	50V V_RRM, 0.52V V_F @ 10A, 25°C, TO-277 package (larger footprint, higher R_θJA)	TO-277 requires more PCB area and delivers 42°C/W R_θJA vs. 25°C/W (heatsink) for SDT10H50P5	Choose only if legacy TO-277 layout reuse is mandatory and thermal headroom permits higher V_F penalty

Compared with VS-10BQ040-M3/45 and SB1050, SDT10H50P5 uniquely balances 50V rating, ultra-low VF, PowerDI5 thermal performance, and automotive-grade process control - making it optimal for new designs prioritizing efficiency, size, and high-temperature reliability.

FAQ

What is the maximum continuous forward current rating at 100°C ambient?

At 100°C ambient temperature, the SDT10H50P5 supports approximately 7.2A average forward current based on the derating curve in Figure 3 of DS40260 Rev. 4–2. This assumes use of the recommended 2"×2" aluminum heatsink, which yields R_θJA = 25°C/W and maintains T_J ≤ 150°C.

Is the PowerDI5 package compatible with standard reflow profiles for lead-free soldering?

Yes - the SDT10H50P5's matte tin-plated terminals meet MIL-STD-202 Method 208 and are qualified for standard IPC/JEDEC J-STD-020D Level 3 reflow profiles. Peak temperature must not exceed 260°C for ≤10 seconds, and moisture sensitivity level 3 requires baking per J-STD-020 prior to reflow if dry-packaging integrity is compromised.

Does this device have AEC-Q101 qualification for automotive use?

No - the SDT10H50P5 is not AEC-Q101 qualified. However, Diodes Incorporated offers automotive-grade variants (e.g., SDT10H50P5Q) with PPAP documentation, AEC-Q101 stress testing, and IATF 16949 manufacturing - contact Diodes or Aetrix for qualified part numbers and qualification reports.

How does the dual-anode configuration (Pins 1 and 3) affect PCB layout?

Pins 1 and 3 are internally paralleled anodes, allowing either pin to serve as the main anode connection. Layout best practice is to route both pins to the same net with symmetric copper traces to balance current sharing and minimize parasitic inductance - critical for minimizing voltage spikes in high-dI/dt switching applications.
