Product details
Overview
DF01MA-E3/45 from Vishay General Semiconductor is a miniature glass-passivated single-phase bridge rectifier rated for 100 V maximum repetitive peak reverse voltage (VRRM), 1.0 A average forward output current (IF(AV)), and 30 A non-repetitive peak surge current (IFSM). It features 1.1 V forward voltage drop at 1.0 A, 5 μA reverse leakage at 25 °C, and operates from –55 °C to +150 °C junction temperature - used in AC/DC full-wave rectification for SMPS and battery chargers.
For engineers reviewing the DF01MA-E3/45 datasheet, DF01MA-E3/45 pinout, DF01MA-E3/45 application, or DF01MA-E3/45 equivalent, key selection criteria include VRRM = 100 V, IF(AV) = 1.0 A at TA = 40 °C, thermal resistance RθJA = 40 °C/W, UL E54214 recognition, and DFM package compatibility with automated PCB insertion.
Technical Context
This device implements a quad-diode single-phase bridge configuration in a compact DFM surface-mount-able package, enabling full-wave rectification without external diode pairing. Its glass passivation ensures stable reverse characteristics up to 125 °C, with 5 μA IR at rated VDC and 500 μA at 125 °C.
The DFM case uses UL 94 V-0 molding compound and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102; it supports solder dip at 275 °C for 10 s and passes JESD 201 Class 1A whisker testing.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU1K-E3/45 | VRRM = 800 V, IF(AV) = 1.0 A, larger GBU package (10.5 mm × 14.2 mm) | Suitable for higher-line-voltage regions (220–240 VAC) where 100 V VRRM is insufficient | Select GBU1K-E3/45 when input voltage exceeds 140 V peak; not pin-compatible due to different footprint and terminal layout |
| DB107S | VRRM = 1000 V, IF(AV) = 1.0 A, SMB package with gull-wing leads | Used in space-constrained designs requiring SMT but lower thermal mass than DFM | Choose DB107S for reflow-only assembly; requires PCB redesign due to different pinout and thermal pad requirements |
Compared with DF01MA-E3/45, GBU1K-E3/45 offers higher voltage blocking but demands more board area and lacks UL E54214 recognition, while DB107S provides superior voltage margin in compact SMB form but delivers lower thermal performance (RθJA ≈ 60 °C/W) and no UL safety listing.

FAQ
What is the maximum operating temperature for DF01MA-E3/45?
The DF01MA-E3/45 has a specified operating junction temperature range of –55 °C to +150 °C. This allows deployment in thermally demanding environments such as enclosed LED drivers or battery chargers near heat-generating components. Derating begins above 40 °C ambient for full IF(AV) = 1.0 A operation, per the datasheet's derating curve. The device must be mounted on PCB copper pads per JEDEC standards to achieve rated thermal performance.
Does DF01MA-E3/45 meet RoHS and lead-free requirements?
Yes, DF01MA-E3/45 is RoHS-compliant and classified as commercial grade under Vishay's E3 suffix designation. It features matte tin-plated leads that satisfy J-STD-002 solderability requirements and pass JESD 201 Class 1A whisker testing. The DFM molding compound meets UL 94 V-0 flammability standards, and the entire construction adheres to Directive 2011/65/EU without exemptions.
What is the forward voltage drop specification for DF01MA-E3/45 at rated current?
The DF01MA-E3/45 exhibits a maximum instantaneous forward voltage drop of 1.1 V per diode at IF = 1.0 A and TA = 25 °C. Since it is a full-wave bridge, the total conduction path includes two series diodes, resulting in ~2.2 V total drop across the bridge at full load - critical for estimating conduction losses in low-voltage-output power supplies.
Is DF01MA-E3/45 suitable for automated PCB assembly processes?
Yes, DF01MA-E3/45 is explicitly designed for automated insertion and surface-mount assembly. Its DFM package supports pick-and-place handling, and its matte tin-plated leads ensure reliable solder wetting during reflow or wave soldering. The device tolerates solder dip at 275 °C for up to 10 seconds per JESD 22-B106, making it compatible with standard PCB assembly lines.
What safety certifications does DF01MA-E3/45 carry?
DF01MA-E3/45 carries UL recognition under file number E54214, confirming compliance with UL/CSA 60950-1 and UL 62368-1 for use in information technology and audio/video equipment. This certification applies specifically to the DFM package variant and validates dielectric strength, flammability (UL 94 V-0), and long-term reliability under rated electrical stress - eliminating need for end-product retesting in many applications.
