Product details
Overview
RH02-T from Diodes Incorporated is a 0.5A surface-mount standard recovery bridge rectifier with 200V peak repetitive reverse voltage, 1.15V max forward voltage at 0.4A, and 30A non-repetitive surge rating - used in AC/DC power supplies for industrial control modules requiring compact, RoHS-compliant rectification.
For engineers reviewing the RH02-T datasheet, RH02-T pinout, RH02-T application, or RH02-T equivalent, this part supports space-constrained designs needing reliable 200V-rated bridge rectification with low thermal resistance (85°C/W) and UL recognition (E364304) under automotive-qualified manufacturing conditions.
Technical Context
This MiniDIP-packaged bridge rectifier integrates four silicon diodes in a single-phase full-wave configuration. It delivers 0.5A average forward current at +40°C ambient and exhibits 150ns maximum reverse recovery time under IF = 0.5A / IR = 1.0A test conditions.
The device uses glass-passivated die construction for enhanced reliability and operates across –55°C to +150°C junction temperature range. Its bright tin-plated leads meet MIL-STD-202 solderability requirements and support automated assembly on PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage per diode leg; defines safe AC input voltage ceiling before breakdown. |
| IF(AV) | 0.5 A @ TA = +40°C - Continuous DC output current capability; derated from 0.5A at +25°C to maintain thermal safety. |
| VF Max | 1.15 V @ 0.4A - Forward voltage drop per diode element; determines conduction loss and heat generation at rated load. |
| IFSM | 30 A - Non-repetitive surge current rating for 8.3ms half-sine wave; enables robustness against line transients and inrush events. |
| tRR Max | 150 ns - Reverse recovery time per element; impacts switching losses and EMI in higher-frequency rectifier applications. |
| RθJA | 85 °C/W - Junction-to-ambient thermal resistance when mounted on PCB; sets minimum copper area needed for thermal management. |
| IR Max | 5 µA @ 25°C - Peak reverse leakage current per element; ensures minimal standby power loss in off-state. |
Pinout & Package
Package: MiniDIP (4-pin, single-in-line), molded plastic body with UL 94V-0 flammability rating, 0.125g mass, and bright tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AC1 | Input AC terminal 1 | One of two alternating-current input pins; connects to primary side of transformer or AC line input. |
| AC2 | Input AC terminal 2 | Second AC input pin; completes full-wave bridge input path with AC1. |
| + (Anode Output) | Positive DC output | Full-wave rectified positive output node; supplies filtered DC bus to downstream regulators or loads. |
| – (Cathode Output) | Negative DC output / Common | Full-wave rectified negative output node; serves as return path and ground reference for DC output. |
Key Features

Applications
| Industrial AC/DC Power Supplies | Automotive Body Control Modules |
|---|---|
Use Scenario: Converting 120/230VAC mains or 12–24VAC auxiliary windings into unregulated DC bus for linear or switching regulators. IC Role / Device Role / Timing Role: Full-wave bridge rectifier providing isolated, polarity-corrected DC output with minimal conduction loss. Use Value: 1.15V VF at 0.4A limits power dissipation to <0.46W, reducing heatsink requirements in sealed enclosures. | Use Scenario: Rectifying AC signals from alternator sensing circuits or HVAC blower motor feedback windings. IC Role / Device Role / Timing Role: Standard recovery bridge converting low-voltage AC to DC for microcontroller ADC inputs or relay driver logic. Use Value: 150ns tRR ensures clean signal capture without ringing-induced false triggering in 1kHz–10kHz sensing bands. |
| Consumer Appliance Power Adapters | LED Driver Input Stages |
Use Scenario: Providing primary-side rectification in Class II isolated flyback adapters for smart home devices. IC Role / Device Role / Timing Role: Compact bridge rectifier enabling miniaturized wall-wart designs with no exposed metal parts. Use Value: MiniDIP footprint (4.5×7.0mm) fits within 12mm² board area, supporting sub-25mm adapter height targets. | Use Scenario: Converting AC line input to DC for constant-current LED drivers in commercial lighting fixtures. IC Role / Device Role / Timing Role: Input-stage bridge delivering stable DC to PFC controller ICs or buck converter stages. Use Value: 30A IFSM withstands repeated cold-start surges from 100k-hour-rated electrolytic capacitors without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU2K (ON Semiconductor) | Same 200V VRRM, but GBU2K has 2A IF(AV) and larger GBU package (10.5×14.5mm). | Higher current rating suits higher-power adapters; larger footprint incompatible with MiniDIP layout. | Select when >0.5A continuous current or higher surge margin is required, and board space allows GBU outline. |
| MB6S (Vishay) | Same MiniDIP package and 0.5A rating, but MB6S has 600V VRRM and 1.1V VF - optimized for universal-input designs. | Higher VRRM enables use with 230VAC + 10% tolerance; slightly lower VF reduces conduction loss at full load. | Select for global-input (90–264VAC) systems where 200V margin is insufficient, without changing PCB layout. |
Compared with GBU2K and MB6S, RH02-T offers optimal balance of miniature size, cost, and 200V-class performance for fixed-input industrial and consumer power supplies where space and thermal constraints dominate.

FAQ
What is the maximum operating temperature for RH02-T?
RH02-T supports a junction temperature range of –55°C to +150°C. Its thermal resistance (RθJA = 85°C/W) means that at 0.5A average forward current and 1.15V forward drop, it dissipates ~0.575W - requiring ≥2.5 cm² of 2-oz copper pour to stay within 125°C junction limit at +40°C ambient.
Is RH02-T suitable for automotive applications?
RH02-T is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not AEC-Q101 qualified out-of-box, Diodes offers automotive-grade variants (e.g., RH02-A) with full qualification - contact Diodes or Aetrix for change-controlled automotive release versions.
How does RH02-T compare to fast recovery bridges like GBU2J?
RH02-T has 150ns reverse recovery time - slower than fast recovery types (e.g., GBU2J: 50ns). It is intended for 50/60Hz line-frequency rectification, not high-frequency SMPS input stages. Using it in >20kHz applications increases switching losses and EMI risk.
Can RH02-T be hand-soldered?
Yes - RH02-T's bright tin-plated leads meet MIL-STD-202 Method 208 solderability requirements. Hand-soldering is feasible with ≤350°C iron tip for <3 seconds per joint. Avoid prolonged heating to prevent internal delamination or plastic body deformation.
