Product details
Overview
10A02-T from Diodes Incorporated is a 10A, 100V peak repetitive reverse voltage (VRRM) general-purpose silicon rectifier diode in R-6 package, featuring 1.0V forward voltage at 10A, 600A non-repetitive surge capability, and low 10µA reverse leakage at 25°C - deployed in AC/DC front-end rectification for industrial power supplies.
For engineers reviewing the 10A02-T datasheet, 10A02-T pinout, 10A02-T application, or 10A02-T equivalent, key selection criteria include VRRM rating, thermal resistance (RθJA = 10°C/W), surge robustness (IFSM = 600A), reverse leakage at elevated temperature, and R-6 mechanical compatibility with high-current PCB layouts.
Technical Context
This axial-lead R-6 packaged rectifier operates in single-phase, half-wave configurations with resistive or inductive loads at 60Hz; capacitive loads require 20% current derating. It exhibits 150pF typical junction capacitance at 1MHz and 4V reverse bias, supporting moderate-speed switching in line-frequency applications.
Thermal performance is defined with leads maintained at ambient temperature at 9.5mm from case; junction-to-ambient thermal resistance is fixed at 10°C/W. Reverse recovery behavior is not specified - confirming its classification as a standard recovery (non-fast) rectifier optimized for 50/60Hz energy conversion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum peak reverse voltage sustainable without breakdown; sets safe operating margin for 70V RMS input circuits. |
| IO (TA=50°C) | 10 A - Continuous average forward current at 50°C ambient; requires heatsinking or airflow above that temperature. |
| VFM @ 10A | 1.0 V - Forward voltage drop defining conduction loss of ~10W at full load, directly impacting thermal design. |
| IFSM (8.3ms) | 600 A - Single half-sine surge rating; enables survival during cold-start inrush into capacitive inputs. |
| RθJA | 10 °C/W - Junction-to-ambient thermal resistance; determines temperature rise under steady-state power dissipation. |
| IRM @ 25°C | 10 µA - Reverse leakage at rated DC blocking voltage; ensures minimal standby power loss in high-impedance circuits. |
| CT @ 1MHz | 150 pF - Junction capacitance affecting EMI filtering design and high-frequency noise coupling in rectifier stage. |
Pinout & Package
R-6 is an axial-leaded, molded plastic package (UL 94V-0) with cathode band polarity marking; terminals are tin-plated, solderable per MIL-STD-202 Method 208. Weight: 2.1g. Moisture sensitivity level: J-STD-020 Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to AC source or transformer secondary; must withstand full surge current and thermal stress. |
| Cathode (Lead 2, banded end) | Forward current exit / DC output node | Routes rectified current to bulk capacitor; polarity marking prevents reverse-bias installation error. |
Key Features
| Feature | Design Value |
|---|---|
| High surge rating | 600A IFSM enables reliable operation during repeated cold-start events in industrial power supplies. |
| Low forward voltage | 1.0V VFM at 10A reduces conduction losses by ~15% versus comparable 1.15V diodes, lowering heatsink requirements. |
| Low reverse leakage | 10µA IRM at 25°C minimizes standby power waste in always-on systems such as HVAC controllers. |
| AEC-Q200 readiness support | Manufactured in IATF 16949 certified facilities; change control and PPAP capability available for automotive-grade variants. |
Applications
| Industrial AC/DC Power Supply | LED Streetlight Driver |
|---|---|
Use Scenario: Rectifying 100–277VAC mains input before bulk capacitor filtering in enclosed outdoor-rated LED drivers. IC Role / Device Role / Timing Role: Primary rectifier conducting full-line current; operates at 50/60Hz with no switching function. Use Value: 10A IO rating supports >100W output; 600A IFSM handles lightning-induced surges common in streetlight grid environments. |
Use Scenario: Input-stage rectification in constant-current LED drivers deployed in humid, high-temperature roadside enclosures. IC Role / Device Role / Timing Role: Unidirectional current path converting AC to pulsating DC; thermally coupled to aluminum housing via lead frame. Use Value: R-6 package's 10°C/W RθJA allows direct mounting to heatsink; 10µA IRM prevents capacitor discharge drift over 50,000-hour lifetime. |
| Automotive Battery Charger | Industrial Motor Control Interface |
Use Scenario: AC input rectification in off-board EV battery chargers handling 240VAC input with high transient immunity requirements. IC Role / Device Role / Timing Role: Front-end diode bridge leg; subjected to repeated 600V+ line transients per ISO 7637-2. Use Value: 100V VRRM provides 2× safety margin over 240VAC RMS; RoHS-compliant tin plating ensures long-term solder joint reliability. |
Use Scenario: Snubberless rectification in three-phase motor drive auxiliary power supplies feeding gate drivers and MCU rails. IC Role / Device Role / Timing Role: Line-frequency rectifier supplying isolated 24V logic rail; operates continuously under variable load. Use Value: 150pF CT limits high-frequency noise injection into control circuitry; 1.0V VFM maintains stable 24V rail under 8A load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR1020CT | Fast recovery (75ns), dual common-cathode configuration, TO-220AC package, 200V VRRM. | Designed for higher-frequency SMPS input stages; unsuitable for direct R-6 footprint replacement. | Select only when fast recovery and higher voltage margin are required - not a drop-in mechanical or electrical substitute. |
| Vishay VS-10BQ015-M3 | Schottky barrier, 15V VRRM, 10A IO, TO-277 package, 0.52V VFM, no reverse recovery. | Optimized for low-voltage, high-efficiency DC-DC inputs; cannot withstand 100V reverse stress. | Use only in ≤15V reverse-bias applications where ultra-low VF and zero Qrr are critical; incompatible with AC line rectification. |
Compared with MUR1020CT and VS-10BQ015-M3, the 10A02-T offers superior surge robustness and line-frequency thermal stability in R-6 form factor, but lacks fast recovery or Schottky efficiency - making it optimal for cost-sensitive, high-reliability 50/60Hz rectification where speed is not required.

FAQ
Is the 10A02-T suitable for use in a 230VAC input power supply?
Yes - with a 100V VRRM rating, the 10A02-T supports 230VAC input only when used behind a step-down transformer or with substantial derating. For direct 230VAC rectification, a minimum 400V VRRM device (e.g., 10A04-T) is required to maintain safe margin against peak line voltage (≈325V) and transients.
Does the 10A02-T have AEC-Q200 qualification?
No - the 10A02-T is not AEC-Q200 qualified. However, Diodes offers AEC-Q200 capable versions within the same R-6 rectifier family upon request, manufactured in IATF 16949 certified facilities with PPAP documentation and automotive-grade change control.
What is the maximum operating temperature for continuous 10A current?
At 10A DC, VFM ≈ 1.0V yields 10W power dissipation. With RθJA = 10°C/W, junction temperature rise is 100°C above ambient. Thus, continuous 10A operation is limited to TA ≤ 50°C - matching the datasheet's IO rating condition and requiring forced air or heatsinking above that ambient.
Can the 10A02-T replace a 1N5408 in existing designs?
Yes - both are 3A-rated DO-201AD rectifiers, but the 10A02-T is not a direct replacement due to its 10A rating and R-6 package. It can upgrade reliability in high-current revisions, provided PCB layout accommodates R-6 lead spacing (8.6–9.1mm) and thermal mass, and VRRM (100V vs. 1000V for 1N5408) is verified for the application.
