Product details
Overview
DF1510S-T from Diodes Incorporated is a surface-mount standard recovery bridge rectifier with 1000 V peak repetitive reverse voltage, 1.5 A average forward current, and 1.1 V maximum forward voltage at 1.5 A. It features glass-passivated die construction, 50 A non-repetitive surge capability, and UL recognition (E364304), designed for AC/DC conversion in offline power supplies and industrial control power stages.
For engineers reviewing the DF1510S-T datasheet, DF1510S-T pinout, DF1510S-T application, or DF1510S-T equivalent, key selection considerations include its 1000 V blocking rating, thermal resistance of 40 °C/W, 25 pF typical junction capacitance per element, and DF-S package compatibility with automated SMT assembly.
Technical Context
This single-phase, full-wave bridge rectifier integrates four silicon diodes in a monolithic DF-S package, configured for standard recovery operation with 1.1 V forward drop at rated DC load. Its 50 A surge rating supports transient line events in unregulated AC-input circuits.
The device operates across –55 °C to +150 °C, with 10 µA max reverse leakage at 25 °C and 500 µA at 125 °C, and exhibits 10.4 A²s I²t fusing rating - critical for coordination with upstream overcurrent protection in mains-fed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands peak reverse voltage up to 1000 V in AC line applications without breakdown. |
| IF(AV) | 1.5 A @ TA = +40°C - Continuous DC output current capability under defined ambient conditions. |
| VF Max | 1.1 V @ IF = 1.5 A - Low conduction loss enables efficient power conversion in low-to-medium power supplies. |
| IFSM | 50 A (8.3 ms half-sine) - Handles short-duration surges such as cold-start inrush or lightning-induced transients. |
| IRM Max | 10 µA @ 25°C, 500 µA @ 125°C - Confirms stable blocking behavior across industrial temperature range. |
| RθJA | 40 °C/W - Junction-to-ambient thermal resistance measured on PCB with 5.0 mm² copper land, guides heatsinking requirements. |
| CT Typ | 25 pF @ 1 MHz, 4 V reverse - Low junction capacitance minimizes high-frequency switching noise and EMI coupling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU10K (ON Semiconductor) | Same 1000 V VRRM, 1.5 A IF, but GBU package (larger, through-hole compatible); VF = 1.05 V @ 1.5 A. | Designed for mixed-technology boards requiring both SMT and TH components; higher thermal mass slows transient response. | Select when legacy through-hole compatibility or higher surge margin (60 A IFSM) is prioritized over SMT density. |
| MB10F (Vishay) | DF-S footprint compatible, 1000 V VRRM, 1.0 A IF rating, VF = 1.1 V; lower current rating and 30 A IFSM. | Suitable only for <1.0 A continuous loads; not recommended for sustained 1.5 A operation without derating. | Choose only for space-constrained designs where load current remains ≤1.0 A and thermal margin is verified. |
Compared with GBU10K and MB10F, DF1510S-T uniquely balances SMT manufacturability, 1.5 A continuous rating, and 1000 V blocking in the compact DF-S package - making it optimal for new industrial and appliance designs targeting high-density, RoHS-compliant production.

FAQ
What is the maximum allowable case temperature for continuous operation?
The DF1510S-T has a maximum junction temperature of +150 °C and operates from –55 °C to +150 °C. With a thermal resistance of 40 °C/W and 1.5 A forward current generating ~1.65 W dissipation, the case temperature must remain below ~85 °C under typical PCB mounting to maintain safe junction limits. Derating curves in Figure 1 confirm 1.5 A is valid only up to +40 °C ambient unless enhanced copper area or airflow is applied.
Is DF1510S-T qualified to AEC-Q101 for automotive use?
No - the DF1510S-T is not AEC-Q101 qualified. The datasheet explicitly states that automotive-qualified versions require specific change control, PPAP capability, and IATF 16949 manufacturing; those parts carry distinct orderable numbers (e.g., DF1510S-AQ). Standard DF1510S-T is intended for industrial and commercial applications only.
Can DF1510S-T be used in capacitive-input filter configurations?
Yes, but with 20% current derating per the datasheet: IO reduces from 1.5 A to 1.2 A. Capacitive-input filters produce higher peak currents and increased RMS heating; this derating ensures junction temperature stays within safe limits and prevents premature failure due to thermal overstress during cold-start or high-line conditions.
What is the polarity marking convention on the DF-S package?
The DF1510S-T uses case marking: a white bar or "+" symbol adjacent to the positive output terminal, and "~" symbols near both AC input pins. Pin 1 (AC1) is located at the top-left corner when the marking is upright; the cathode output (–) is diagonally opposite the anode (+), consistent with standard bridge rectifier orientation in the DF-S outline drawing.
