Product details
Overview
10A04-B from Diodes Incorporated is a 400 V peak repetitive reverse voltage, 10 A average rectified output current, single-phase silicon bridge rectifier in R-6 package with 1.0 V forward voltage at 10 A and 600 A non-repetitive surge capability-used in AC/DC front-end power supplies for industrial motor drives.
For engineers reviewing the 10A04-B datasheet, 10A04-B pinout, 10A04-B application, or 10A04-B equivalent, key selection criteria include VRRM rating, thermal resistance (RθJA = 10 °C/W), surge robustness (IFSM = 600 A), and RoHS-compliant tin-plated leads for high-reliability soldering in automotive-qualified production environments.
Technical Context
This device implements a monolithic single-phase full-wave bridge rectifier topology, integrating four diodes in one R-6 molded plastic package with cathode band polarity marking. It operates under 60 Hz resistive or inductive loads without derating, but requires 20% current derating for capacitive loads.
Thermal performance is defined with leads maintained at ambient temperature at 9.5 mm from case, enabling direct heatsink mounting or PCB trace-based thermal management. Junction-to-ambient thermal resistance is fixed at 10 °C/W, and reverse leakage remains ≤10 µA at 25°C and ≤100 µA at 100°C under rated DC blocking voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum peak reverse voltage the device blocks reliably in repetitive AC operation. |
| IO (TA = +50°C) | 10 A - Continuous DC output current capability with leads held at 50°C ambient, defining usable power-handling capacity. |
| VFM @ 10 A | 1.0 V - Forward voltage drop at rated current, directly determining conduction loss (10 W per device at full load). |
| IFSM (8.3 ms) | 600 A - Single half-sine surge current rating, supporting inrush tolerance in transformer-coupled supplies. |
| RθJA | 10 °C/W - Junction-to-ambient thermal resistance, enabling thermal design with known temperature rise per watt dissipated. |
| IRM @ 25°C | 10 µA - Reverse leakage at rated voltage and room temperature, critical for low-power standby and high-impedance sensing circuits. |
Pinout & Package
Package: R-6 molded plastic case (UL 94V-0), 2.1 g weight, cathode band polarity marking, tin-plated leads solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Input AC terminal 1 | One of two alternating-current input nodes; connects to transformer secondary or line input. |
| AC2 | Input AC terminal 2 | Second AC input node; completes full-wave bridge input path with AC1. |
| + (Anode Common) | Positive DC output | Full-wave rectified positive output node; ties internally to anodes of two diodes. |
| – (Cathode Common) | Negative DC output | Full-wave rectified negative output node; ties internally to cathodes of two diodes and marked with band. |
Key Features
| Feature | Design Value |
|---|---|
| High surge rating | 600 A IFSM enables reliable startup in high-inertia motor drives and transformer-fed systems. |
| Low forward voltage | 1.0 V VFM at 10 A reduces conduction losses by ~15% versus comparable 1.15 V devices, improving efficiency in 24–48 V systems. |
| RoHS-compliant finish | Tin-plated leads meet EU RoHS 3 (2015/863/EU) and support lead-free reflow profiles without whisker risk. |
| Automotive-ready qualification path | Manufactured in IATF 16949-certified facilities and PPAP-capable-enables rapid qualification for AEC-Q101 stress-tested designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU4K (ON Semiconductor) | Same R-6 package, 400 V VRRM, but 1.1 V VFM and 30 A IFSM rating. | Limited surge margin in high-inrush transformer applications. | Prefer when lower cost is prioritized over surge robustness and thermal efficiency. |
| GBU4J (Vishay) | Identical 400 V/10 A rating and 1.0 V VFM, but moisture sensitivity level 2a (vs Level 1 for 10A04-B). | Requires bake-out before reflow if exposed to humidity >60% RH for >12 hours. | Choose only when existing assembly lines already handle Level 2a handling protocols. |
Compared with GBU4K and GBU4J, the 10A04-B offers superior thermal resistance (10 °C/W vs typical 12–14 °C/W), tighter IRM control at elevated temperature, and Level 1 moisture sensitivity-making it optimal for high-volume, high-reliability industrial power supplies where process consistency and long-term stability are critical.

FAQ
Is the 10A04-B suitable for use in AEC-Q101 qualified automotive applications?
No-the 10A04-B itself is not AEC-Q101 qualified, but it is manufactured in IATF 16949-certified facilities and supports PPAP documentation. Customers requiring automotive qualification must engage Diodes' automotive team for custom AEC-Q101 stress testing and certification of this part number under specific program requirements.
What is the maximum allowable case temperature during continuous operation?
The maximum junction temperature is +150°C, and with RθJA = 10 °C/W, the case temperature must remain ≤140°C at 10 A DC load (assuming negligible internal thermal gradient). Derating curves in DS28010 show 10 A is valid only up to +50°C ambient unless heatsinking is applied.
Can the 10A04-B be used in a center-tap transformer configuration?
No-it is a full-wave bridge rectifier with fixed AC1/AC2 inputs and common +/– outputs; it cannot replace dual-diode center-tap rectifiers. For center-tap use, discrete diodes such as 1N5408 or MUR1040 are required instead.
Does the "-B" suffix indicate a different electrical specification than "-T"?
No-the "-B" suffix denotes bulk packaging (loose parts in tube or tray), while "-T" indicates tape-and-reel. Electrical specifications, package dimensions, and thermal characteristics are identical between 10A04-B and 10A04-T per DS28010 Rev. 6.
