Product details
Overview
RTT410 from Diodes Incorporated is a 4A surface-mount fast recovery bridge rectifier rated for 1000V peak repetitive reverse voltage, with 1.3V forward voltage at 4A and 5μA leakage at 1000V/25°C. It features glass-passivated die construction, TTL package, and is designed for AC–DC full-wave rectification in SMPS, LED lighting, and battery chargers.
For engineers reviewing the RTT410 datasheet, RTT410 pinout, RTT410 application, or RTT410 equivalent, key selection criteria include its 1000V VRRM rating, 4A average output current at TC = +100°C, 250ns reverse recovery time, low-profile TTL package, and UL recognition (E364304) for safety-critical power conversion designs.
Technical Context
The RTT410 integrates four fast-recovery diodes in a single-phase bridge configuration with common-cathode and common-anode terminals. Its 250ns tRR and 42pF junction capacitance support high-frequency switching in offline SMPS up to ~100kHz without excessive EMI generation.
Thermal design is enabled by RθJC = 5°C/W and RθJL = 8°C/W per element, allowing 4A continuous conduction at TC = +100°C. The device uses glass passivation for stable reverse characteristics across –55°C to +150°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands peak AC line transients up to 1000V without breakdown |
| IO (at TC = +100°C) | 4 A - Sustains full-rated DC output current when heatsinked to 100°C case temperature |
| VF (at IF = 4A, TA = +25°C) | 1.3 V - Limits conduction loss to ≤5.2W per diode pair under nominal load |
| tRR | 250 ns - Enables efficient operation in 50–100kHz switch-mode supplies with minimal switching loss |
| IR (at VR = 1000V, TA = +25°C) | 5 μA - Ensures low standby power loss in high-impedance hold-up circuits |
| IFSM (8.3ms) | 100 A - Survives cold-start inrush surges in universal-input AC/DC adapters |
| RθJC | 5 °C/W - Supports thermal management using minimal copper area on PCB for cost-sensitive designs |

Applications
| LED Lighting Driver | Universal Input AC/DC Adapter |
|---|---|
Use Scenario: Off-line constant-current LED driver for commercial downlights with 90–265V AC input. IC Role / Device Role / Timing Role: Primary bridge rectifier converting AC line to unregulated DC bus prior to PFC and DC/DC stages. Use Value: 1000V VRRM safely handles 265V AC peaks plus line surges; 250ns tRR minimizes switching noise coupling into sensitive current-sense circuitry. | Use Scenario: 36W dual-port USB-C PD adapter with active clamp flyback topology. IC Role / Device Role / Timing Role: Input-stage full-wave rectifier feeding bulk capacitor and PFC controller. Use Value: 4A IO rating supports >30W continuous output; low VF reduces thermal stress on primary-side heatsink. |

Use Scenario: Standby and main power supply in smart washing machine control board. IC Role / Device Role / Timing Role: AC–DC front-end rectifier supplying 12V/5V rails to MCU, display, and motor drivers. Use Value: UL recognition simplifies IEC 60335-1 compliance; TTL package enables automated placement on dense control PCBs. | Use Scenario: Compact 27W GaN-based charger for VoIP phones and small network devices. IC Role / Device Role / Timing Role: High-efficiency bridge rectifier in quasi-resonant flyback with 100kHz+ operation. Use Value: 42pF CT and 250ns tRR limit capacitive coupling and reverse recovery spikes, preserving GaN FET gate integrity. |
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 1000V VRRM, 4A IO, but TO-220AC package; VF = 1.1V @ 4A; tRR = 500ns | Requires through-hole mounting and larger heatsinking; higher tRR increases EMI risk in high-frequency SMPS | Prefer for legacy through-hole designs where thermal mass outweighs size constraints |
| MB10F (Vishay) | TTL package, 1000V VRRM, 1A IO, VF = 1.1V @ 1A; tRR = 250ns; smaller footprint | Rated only for ≤1A continuous; unsuitable for >15W output without parallel use | Select only for low-power auxiliary supplies or dual-output systems with split rectification |
Compared with GBU4K and MB10F, the RTT410 uniquely balances 4A current capability, surface-mount TTL packaging, 250ns tRR, and UL recognition-making it optimal for space-constrained, high-efficiency, safety-certified 20–40W AC/DC converters.

FAQ
What is the maximum allowable case temperature for continuous 4A operation?
The RTT410 is rated for 4A average output current at TC = +100°C, as specified in its Maximum Ratings table. Operation above this temperature requires derating per the Forward Current Derating Curve (Figure 1). At TC = +125°C, the safe continuous current drops to approximately 3.2A due to thermal resistance limits and junction temperature constraints.
Is the RTT410 suitable for automotive applications?
The RTT410 is not AEC-Q101 qualified and is not intended for automotive use unless explicitly validated by Diodes Incorporated for that application. While it operates from –55°C to +150°C, automotive qualification requires PPAP documentation, IATF 16949 manufacturing, and specific change control-none of which apply to the standard RTT410-13 part number.
Does the TTL package support reflow soldering per JEDEC J-STD-020?
Yes-the RTT410's TTL package has Moisture Sensitivity Level 1 per J-STD-020, meaning it can be subjected to unlimited floor life and standard Pb-free reflow profiles (peak 260°C) without baking. Its matte tin finish ensures reliable wetting and joint formation during automated SMT assembly.
How does the 250ns reverse recovery time impact EMI performance?
A 250ns tRR significantly reduces high-frequency ringing and dv/dt-induced noise during commutation, lowering both conducted and radiated EMI in switch-mode supplies. This allows simpler EMI filter designs and helps meet CISPR-32 Class B limits without adding snubber networks or ferrite beads on the AC input lines.
