Product details
Overview
DF15005S-E3/77 from Vishay General Semiconductor is a miniature glass-passivated single-phase surface-mount bridge rectifier with 50 V maximum repetitive peak reverse voltage, 1.5 A average forward output current, and 50 A non-repetitive surge capability. It uses a DFS package, supports automated placement, and is rated for operation from –55 °C to +150 °C - deployed in AC/DC full-wave rectification for compact switch-mode power supplies.
For engineers reviewing the DF15005S-E3/77 datasheet, DF15005S-E3/77 pinout, DF15005S-E3/77 application, or DF15005S-E3/77 equivalent, key selection criteria include its 1.1 V forward voltage at 1.5 A, 5 μA reverse leakage at 25 °C, MSL Level 1 rating, UL E54214 recognition, and compatibility with J-STD-002 soldering standards.
Technical Context
This device implements a quad-diode full-wave bridge configuration in a single DFS surface-mount package, enabling compact AC-to-DC conversion without external interconnects. Its glass passivation ensures stable junction characteristics under thermal cycling and humidity exposure.
The DF15005S-E3/77 is optimized for high-surge environments with 50 A IFSM and 10 A²s fusing rating, while maintaining low thermal resistance (RθJA = 40 °C/W) when mounted on 13 mm × 13 mm copper pads - critical for thermally constrained SMPS and adapter designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - defines maximum AC input voltage the bridge can block without breakdown; sets upper limit for 35 V RMS input systems. |
| IF(AV) | 1.5 A at TA = 40 °C - continuous DC output current capability under standard PCB mounting conditions. |
| VF @ 1.5 A | 1.1 V - total forward drop across two series diodes in conduction path; determines conduction loss and thermal load. |
| IR @ 25 °C | 5 μA - low leakage preserves efficiency in standby and light-load operation of battery chargers and adapters. |
| IFSM | 50 A - withstands inrush surges during cold-start of lighting ballasts and SMPS without degradation. |
| TJ max. | +150 °C - enables reliable operation in enclosed, high-ambient industrial or automotive auxiliary power modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K-E3/54 | Higher VRRM (800 V), larger GBU package (19.0 mm × 12.7 mm), IF(AV) = 4 A | Suitable for higher-voltage industrial inputs; requires larger PCB area and different thermal pad layout | Select when >50 V reverse blocking or >1.5 A continuous current is required |
| DB107S | Same DFS package, but VRRM = 1000 V and IF(AV) = 1.0 A; VF = 1.1 V at 1.0 A | Lower average current rating limits use in sustained 1.5 A loads; better for high-V, low-I applications | Choose only if 1000 V blocking is mandatory and load current remains ≤1.0 A |
Compared with GBU4K-E3/54 and DB107S, the DF15005S-E3/77 offers optimal balance of compact DFS footprint, 50 V rating, and 1.5 A capacity - making it ideal for space-constrained, low-voltage AC/DC stages where thermal management and board area are critical.

FAQ
What is the maximum ambient temperature for continuous operation of DF15005S-E3/77?
The DF15005S-E3/77 is rated for operation from –55 °C to +150 °C junction temperature. When mounted on 13 mm × 13 mm copper pads per datasheet condition, its maximum ambient temperature for 1.5 A average forward current is approximately +85 °C - derived from RθJA = 40 °C/W and TJ max = 150 °C. Derating is required above this ambient level, as shown in Figure 1 of the DF15005S-E3/77 datasheet.
Does DF15005S-E3/77 support lead-free reflow soldering?
Yes, DF15005S-E3/77 meets J-STD-020 MSL Level 1 with a maximum peak reflow temperature of 260 °C, fully compatible with standard lead-free soldering profiles. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102, and the E3 suffix confirms RoHS compliance and JESD201 Class 1A whisker resistance - ensuring reliable interconnect integrity after reflow.
What is the polarity marking convention for DF15005S-E3/77?
The DF15005S-E3/77 uses body marking to indicate polarity: a white band identifies the +DC terminal, while the opposite corner marks the –DC terminal. The ~AC1 and ~AC2 terminals are unmarked and interchangeable for AC input. This marking aligns with industry-standard bridge rectifier orientation and simplifies visual verification during manual inspection or AOI.
How does the thermal resistance of DF15005S-E3/77 compare between junction-to-ambient and junction-to-lead?
Per the DF15005S-E3/77 datasheet, RθJA is 40 °C/W (measured on 13 mm × 13 mm PCB copper pads), while RθJL is 15 °C/W - indicating significantly lower thermal impedance when heat is conducted directly through the leads to a heatsink or thermal pad. This dual-path thermal design allows flexibility: RθJL supports high-pulse-current operation via lead conduction, while RθJA governs steady-state PCB-based dissipation.
Is DF15005S-E3/77 suitable for use in medical-grade power supplies?
The DF15005S-E3/77 carries UL recognition file E54214 and meets IEC/EN 62368-1 basic insulation requirements for AC/DC conversion, but it is not specifically certified to IEC 60601-1. For medical applications, system-level validation is required - including creepage/clearance verification, isolation testing, and risk analysis. DF15005S-E3/77 may be used in non-isolated auxiliary rails or as part of a certified design, subject to full end-equipment qualification.
