Product details
Overview
DF15005S-T from Diodes Incorporated is a surface-mount standard recovery bridge rectifier with 50 V peak repetitive reverse voltage (VRRM), 1.5 A average forward rectified current (IO), and 1.1 V maximum forward voltage (VFM) per element at 1.5 A - used in AC/DC power supplies for industrial control modules requiring compact, RoHS-compliant rectification.
For engineers reviewing the DF15005S-T datasheet, DF15005S-T pinout, DF15005S-T application, or DF15005S-T equivalent, this part supports high-surge-capability (50 A IFSM), low-thermal-resistance (40 °C/W RθJA) operation in DF-S package, with UL recognition and automotive-grade manufacturing capability.
Technical Context
This bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration with glass-passivated die construction, enabling stable performance under transient surge conditions up to 50 A (8.3 ms half-sine). Its 50 V VRRM rating targets low-voltage AC input stages such as 12–24 VAC transformer outputs.
The device operates across –55 °C to +150 °C, with 10 µA peak reverse current (IRM) at 25 °C and 500 µA at 125 °C, supporting reliable blocking in thermally demanding environments. Thermal resistance of 40 °C/W is measured on a PCB with 5.0 mm² copper land areas.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage per diode leg; defines safe AC input range for 12–24 VAC systems. |
| IO | 1.5 A @ TA = +40°C - Continuous DC output current capability; derated above ambient temperature per Fig. 1. |
| VFM | 1.1 V @ IF = 1.5 A - Forward voltage drop per diode element; determines conduction loss and thermal load at rated current. |
| IFSM | 50 A (8.3 ms) - Non-repetitive surge rating; withstands inrush currents from capacitive inputs or cold-start conditions. |
| RθJA | 40 °C/W - Junction-to-ambient thermal resistance on standard PCB layout; enables thermal design with minimal heatsinking. |
| IRM | 10 µA @ 25°C, 500 µA @ 125°C - Reverse leakage per element; impacts standby power and high-temperature blocking integrity. |
| CT | 25 pF @ 1 MHz, 4 V - Junction capacitance per element; influences EMI behavior and high-frequency rectifier noise. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | AC Input Terminal 1 | One AC input node of full-wave bridge; connects to transformer secondary or AC line input. |
| AC2 | AC Input Terminal 2 | Second AC input node; completes AC path for full-wave rectification. |

FAQ
What is the maximum allowable junction temperature for DF15005S-T?
The DF15005S-T has a specified operating junction temperature range of –55 °C to +150 °C. This limit is defined in the Absolute Maximum Ratings table of DS17002 Rev. 14–2. Sustained operation above +150 °C risks irreversible parametric shift or bond-wire failure.
Can DF15005S-T be used in place of DF1501S-T?
No - DF15005S-T (50 V VRRM) and DF1501S-T (100 V VRRM) differ in peak reverse voltage rating and are not interchangeable without verifying system-level reverse stress margins. Substitution requires redesign validation against worst-case AC transients and derating curves.
Is DF15005S-T qualified to AEC-Q101?
DF15005S-T is not explicitly listed as AEC-Q101 qualified in DS17002. However, Diodes states that automotive-grade versions with AEC-Q101 qualification, PPAP capability, and IATF 16949 manufacturing are available upon request - contact Diodes or authorized representatives for qualified variants.
What is the recommended PCB pad layout for DF-S package?
The recommended pad layout for DF-S is published in Diodes' package outline documentation (available at diodes.com/package-outlines.html). It specifies copper land dimensions matching the 7.4–7.9 mm × 6.2–6.5 mm body, with thermal relief for solder joint reliability and optimized heat dissipation via internal copper planes.
