Diodes Incorporated PD3S130H-7

Overview

PD3S130H-7 from Diodes Incorporated is a 1 A, 30 V Schottky rectifier in the ultra-small PowerDI323 surface-mount package. It is intended for compact low-voltage rectification, switching, recirculating, and polarity-protection circuits where low forward voltage and board area matter.

For engineers reviewing the PD3S130H-7 datasheet, PD3S130H-7 pinout, PD3S130H-7 application, or PD3S130H-7 equivalent, this diode is most relevant for handheld devices, compact DC-DC converters, battery-powered equipment, low-voltage power rails, reverse-polarity protection, portable industrial modules, and repair work requiring 30 V blocking, 1 A current, 470 mV forward-voltage class, 22 A surge handling, and PowerDI323 assembly.

Technical Context

PD3S130H-7 is a low-voltage Schottky rectifier, so its value is strongest where conduction loss and package size are more important than high reverse-voltage rating. The 30 V class suits low-voltage rails, battery systems, and compact converter outputs with controlled transients.

The PowerDI323 package gives a very small footprint while retaining better current usability than many tiny signal packages. Because the package is physically small, real current capability depends heavily on pad design, copper area, ambient temperature, and the peak-to-average current waveform.

Key Specifications

Pinout & Package

PD3S130H-7 uses a two-terminal PowerDI323 package. The cathode band identifies the cathode terminal, while the opposite terminal is the anode. The small package footprint requires careful pad layout and polarity inspection, especially in dense converter layouts.

Key Features

• 1 A, 30 V Schottky rectifier in PowerDI323 package.
• Low 470 mV maximum forward-voltage class at 1 A.
• 22 A forward impulse surge-current capability.
• 40 pF capacitance at 10 V and 1 MHz.
• Wide -65°C to +150°C junction temperature range.
• Ultra-small package for dense portable and low-voltage power boards.
• Useful as a polarity-protection, recirculating, or switching diode.
• Tape-and-reel format for automated assembly.

Applications

Equivalent & Alternatives

When evaluating PD3S130H-7 equivalent devices, compare reverse voltage, forward current, forward voltage at load current, leakage at temperature, capacitance, surge current, PowerDI323 footprint, cathode marking, and package thermal behavior.

Quality

PD3S130H-7 should be sourced as original Diodes Incorporated PowerDI323 Schottky rectifiers through traceable and controlled supply channels. Quality checks may include package inspection, cathode-band verification, reel label review, solderability testing, forward-voltage screening, reverse-leakage testing, capacitance-sensitive application review, surge-risk review, and incoming inspection for dense low-voltage assemblies.

Availability

PD3S130H-7 is available at Aetrix Electronics and suitable for portable DC-DC converters, low-voltage rail steering, reverse-polarity protection, battery-powered devices, compact industrial modules, handheld electronics, and repair programs requiring a 1 A, 30 V PowerDI323 Schottky rectifier.

Supply support may include scheduled delivery planning, volume procurement support, BOM continuity assistance, traceable sourcing management, and lifecycle availability coordination for portable-device manufacturers, industrial electronics builders, contract manufacturers, power-module producers, and repair teams.

For production deployment, confirming the PowerDI323 footprint, cathode orientation, 30 V margin, 1 A current waveform, forward-voltage loss, leakage budget, capacitance impact, surge exposure, solder profile, and sourcing continuity helps reduce low-voltage diode risk.

FAQ

What is PD3S130H-7 used for?

PD3S130H-7 is used for compact low-voltage rectification, rail steering, reverse-polarity protection, and DC-DC converter diode paths. The 1 A rating, 30 V reverse-voltage class, and low forward voltage make PD3S130H-7 useful in portable, battery-powered, and dense power-management boards.

What package does PD3S130H-7 use?

PD3S130H-7 uses a PowerDI323 surface-mount package. This very small package reduces board area but depends strongly on pad design and copper for thermal performance. When using PD3S130H-7, check cathode marking, footprint, solder profile, and temperature rise carefully.

What is the forward voltage of PD3S130H-7?

PD3S130H-7 has a 470 mV maximum forward-voltage class at 1 A. That low drop can improve efficiency in battery and converter circuits. Actual PD3S130H-7 loss depends on forward current, waveform duty cycle, ambient temperature, and the thermal layout around the package.

Can PD3S130H-7 be used for polarity protection?

PD3S130H-7 can be used for polarity protection in low-voltage systems when the 30 V reverse rating, 1 A current capability, and leakage behavior match the circuit. The small package makes PD3S130H-7 attractive near connectors or power-management ICs on compact boards.

What should be checked before replacing PD3S130H-7?

Before replacing PD3S130H-7, check reverse voltage, forward current, forward voltage, leakage at temperature, capacitance, surge current, PowerDI323 footprint, cathode-band orientation, thermal resistance, soldering process, package height, and whether the system requires Diodes Incorporated sourcing.
