Product details
Overview
10A04-T from Diodes Incorporated is a 400 V peak repetitive reverse voltage general-purpose silicon rectifier diode in R-6 package, rated for 10 A average forward current, 600 A non-repetitive surge current, and 1.0 V forward voltage at 10 A, used in AC/DC power supplies and industrial motor drive front-end rectification.
For engineers reviewing the 10A04-T datasheet, 10A04-T pinout, 10A04-T application, or 10A04-T equivalent, key selection criteria include VRRM=400 V, IO=10 A, IFSM=600 A, VFM=1.0 V @10 A, and RθJA=10 °C/W - critical for thermal design and reliability in high-current linear and switching power conversion stages.
Technical Context
This device operates as a single-phase, half-wave silicon junction rectifier optimized for mains-frequency (60 Hz) resistive or inductive loads. It exhibits low reverse leakage (10 µA @25°C, 100 µA @100°C) and a typical junction-to-ambient thermal resistance of 10 °C/W under standard mounting conditions.
The R-6 package supports high surge capability (600 A, 8.3 ms half-sine) while maintaining low forward conduction loss (1.0 V @10 A) and moderate junction capacitance (150 pF @1 MHz, 4 V). Polarity is marked by a cathode band; leads are tin-plated and solderable per MIL-STD-202, Method 208.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum peak reverse voltage the diode blocks without breakdown; defines safe operating range in 230 VAC line rectification with margin. |
| IO | 10 A @ TA = +50°C - continuous DC output current rating with leads held at ambient at 9.5 mm from case; sets heatsink sizing baseline. |
| IFSM | 600 A (8.3 ms) - non-repetitive surge current handling; enables robustness against inrush and short-circuit transients in power supplies. |
| VFM | 1.0 V @ IF = 10 A - forward voltage drop at rated current; determines conduction loss (10 W dissipation at full load). |
| RθJA | 10 °C/W - thermal resistance from junction to ambient; used to calculate max junction temperature rise (ΔTJ = Pd × RθJA). |
| IRM | 10 µA @25°C / 100 µA @100°C - reverse leakage current; impacts standby power and high-impedance bias stability. |
| CT | 150 pF @1 MHz, 4 V - junction capacitance; influences high-frequency switching noise and EMI filter design in SMPS input stages. |
Pinout & Package
Package: R-6 molded plastic case (UL 94V-0), cathode-banded polarity, tin-plated leads, 2.1 g weight, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary; must withstand full surge current and thermal stress during conduction. |
| Cathode | Forward current exit point | Connected to bulk capacitor or load; marked by band; carries full output current and defines reference for downstream filtering. |
Key Features
| Feature | Design Value |
|---|---|
| High surge rating | 600 A peak (8.3 ms) - enables reliable operation during cold-start inrush without failure. |
| Low forward voltage | 1.0 V @10 A - reduces conduction loss by ~15% vs. comparable 1.15 V diodes, improving efficiency in linear supplies. |
| Low reverse leakage | 10 µA @25°C - minimizes standby power loss and prevents capacitor discharge in hold-up circuits. |
| RoHS-compliant finish | Tin-plated leads, lead-free, halogen-free - meets global environmental compliance requirements for industrial and automotive-adjacent designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R04DJF | 400 V VRRM, 10 A IO, but TO-220AC package; 0.95 V VFM @10 A; faster recovery (trr ≈ 35 ns) | Designed for higher-frequency switching (e.g., PFC stages); not optimized for 60 Hz line frequency | Select when lower VFM and faster recovery are needed in SMPS input stages; requires different PCB footprint and heatsinking. |
| ON Semi MUR1040 | 400 V VRRM, 10 A IO, DO-201AD package; 1.3 V VFM @10 A; 50 ns trr; higher RθJA (~30 °C/W) | Higher forward loss and thermal resistance limit use to lower-duty-cycle or lower-power applications | Choose only for space-constrained legacy designs where R-6 footprint is unavailable; expect ~3 W higher conduction loss and larger heatsink. |
Compared with STTH10R04DJF and MUR1040, the 10A04-T delivers optimal balance of surge robustness (600 A), thermal performance (10 °C/W), and cost-effective R-6 packaging for 50/60 Hz industrial rectification - making it preferred for mains-frequency, high-reliability power conversion where fast recovery is unnecessary.

FAQ
Is the 10A04-T RoHS compliant and lead-free?
Yes. The 10A04-T features a lead-free, RoHS-compliant finish per EU Directives 2011/65/EU (RoHS 2) and 2015/863/EU (RoHS 3), with tin-plated leads meeting MIL-STD-202, Method 208 solderability requirements and UL 94V-0 flammability rating.
What is the maximum junction temperature and how is it calculated?
The 10A04-T has an operating junction temperature range of –65°C to +150°C. At 10 A DC forward current and 1.0 V forward drop, power dissipation is 10 W. With RθJA = 10 °C/W, ΔTJ = 100°C above ambient - so maximum ambient must be ≤ +50°C for TJ ≤ +150°C under natural convection.
Can the 10A04-T be used in full-wave bridge configurations?
Yes. Four 10A04-T diodes can be assembled into a discrete full-wave bridge rectifier. Its 400 V VRRM and 600 A IFSM make it suitable for 230 VAC inputs; however, ensure symmetrical thermal layout and equal current sharing via matched devices and PCB copper balancing.
Is the 10A04-T qualified for automotive applications?
No. While Diodes offers AEC-Q101-qualified rectifiers, the 10A04-T is not automotive-qualified. It lacks PPAP documentation, AEC-Q101 stress testing, and IATF 16949 manufacturing certification - intended for industrial, commercial, and infrastructure use only.
