Product details

Overview

PR3004-T from Diodes Incorporated is a 400 V, 3.0 A fast recovery rectifier diode in DO-201AD package, featuring 150 ns reverse recovery time, 1.2 V forward voltage at 3.0 A, and 150 A non-repetitive surge capability-used in AC/DC front-end rectification for industrial power supplies and LED drivers.

For engineers reviewing the PR3004-T datasheet, PR3004-T pinout, PR3004-T application, or PR3004-T equivalent, key selection criteria include peak repetitive reverse voltage (400 V), average rectified current (3.0 A @ 90°C), thermal resistance (15 °C/W), reverse recovery time (150 ns), and RoHS-compliant tin-plated leads.

Technical Context

This device implements a diffused-junction silicon PN structure optimized for fast switching in single-phase, half-wave rectification under resistive or inductive loads at 60 Hz. It supports surge overload up to 150 A (8.3 ms half-sine) and maintains low reverse leakage (5.0 mA @ 25°C, 100 mA @ 100°C) at rated blocking voltage.

Thermal design relies on junction-to-ambient thermal resistance of 15 °C/W with leads held at ambient temperature at 9.5 mm from case; total capacitance is 50 pF at 1.0 MHz and 4.0 V reverse bias, enabling stable operation in high-frequency auxiliary circuits.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - maximum repetitive reverse voltage; defines safe DC blocking limit in bridge or half-wave configurations
I_O	3.0 A @ T_A = 90°C - continuous forward current rating with derating above ambient; requires heatsinking above 90°C
V_FM	1.2 V @ I_F = 3.0 A - forward conduction loss directly impacts efficiency and thermal rise in power stage
t_rr	150 ns - fast recovery enables reduced switching losses in higher-frequency SMPS designs up to ~100 kHz
R_θJA	15 °C/W - thermal resistance determines junction temperature rise under natural convection; critical for reliability margin
I_FSM	150 A (8.3 ms) - surge rating supports inrush current handling during cold-start in AC-input systems
C_T	50 pF @ 1 MHz, 4 V - low junction capacitance minimizes EMI and improves high-frequency rectifier stability

Pinout & Package

DO-201AD molded plastic package with axial leads; cathode identified by band marking; polarity-critical mounting; lead finish is matte tin, solderable per MIL-STD-202 Method 208.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Positive input terminal for forward conduction	Connected to AC source or transformer secondary; must withstand full surge current path
Cathode	Negative output terminal; marked with band	Drives filter capacitor or load; carries full average output current and ripple

Key Features

Feature	Design Value
Fast recovery time	150 ns enables efficient operation in 50–100 kHz SMPS without excessive switching loss
High surge rating	150 A peak supports robust inrush handling in unregulated AC/DC inputs
Low forward voltage	1.2 V at 3.0 A reduces conduction loss and thermal stress vs. standard rectifiers
RoHS-compliant finish	Tin-plated leads meet EU Directive Annex Note 7 exemption for high-temp soldering
UL 94V-0 case	Molded plastic housing provides flame-retardant mechanical protection in enclosed power modules

Applications

Industrial AC/DC Power Supplies

LED Driver Input Rectification

Use Scenario: Single-phase rectification in 85–265 VAC offline SMPS for PLCs and motor controllers.

IC Role / Device Role / Timing Role: Primary-side power diode converting AC line to pulsating DC before bulk capacitor filtering.

Use Value: 150 ns t_rr limits reverse recovery loss during high-frequency switching, improving overall efficiency by ~0.8% over standard 1N540x series.

Use Scenario: Input-stage rectification in constant-current LED drivers for street lighting.

IC Role / Device Role / Timing Role: Half-wave rectifier feeding boost PFC stage; handles 3.0 A average current with minimal thermal drift.

Use Value: 15 °C/W R_θJA allows operation at 90°C ambient without forced air, reducing system cooling cost.

Capacitor-Input Filter Circuits

UPS Battery Charger Front-End

Use Scenario: High-capacitance input filter in telecom rectifiers where low ESR caps demand low-impedance rectification.

IC Role / Device Role / Timing Role: Fast-recovery diode minimizing voltage overshoot and ringing during capacitor charging transients.

Use Value: 50 pF C_T suppresses high-frequency resonance with bulk capacitors, reducing conducted EMI by 6–8 dBµV.

Use Scenario: Mains-fed battery charger in line-interactive UPS with automatic transfer switching.

IC Role / Device Role / Timing Role: Main rectifier handling both normal AC input and generator-backed operation with repeated surge events.

Use Value: 150 A I_FSM rating ensures reliable cold-start under full battery discharge recovery conditions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast recovery rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH3L04	Same V_RRM (400 V), lower I_O (3.0 A @ 110°C), faster t_rr (35 ns), higher V_F (1.3 V)	Better suited for higher-frequency (>200 kHz) PFC stages where recovery speed dominates conduction loss	Select when operating frequency exceeds 120 kHz and thermal margin permits higher V_F
ON Semi MUR3040	Higher V_RRM (400 V), same I_O, slower t_rr (500 ns), identical package (DO-201AD)	Acceptable for lower-frequency (<50 kHz) rectification where surge robustness is prioritized over recovery speed	Choose if cost sensitivity outweighs efficiency targets and layout EMI constraints are relaxed

Compared with STTH3L04 and MUR3040, PR3004-T delivers optimal balance of 150 ns recovery, 1.2 V forward drop, and 150 A surge rating in DO-201AD-making it preferred for 60–100 kHz industrial power supplies requiring thermal resilience and EMI control.

FAQ

What is the maximum allowable junction temperature for PR3004-T?

The absolute maximum junction temperature is +150°C, and the device is rated for continuous operation up to this limit. Derating begins at ambient temperatures above 90°C, where average forward current drops linearly to zero at 150°C ambient-verified via thermal resistance of 15 °C/W and thermal test conditions in DS26014 Rev. 4.

Can PR3004-T be used in full-wave bridge configurations?

Yes-PR3004-T is a single die rectifier intended for use in discrete full-wave bridges. Its 400 V V_RRM, 150 A I_FSM, and DO-201AD package allow direct substitution in standard bridge layouts; however, thermal coupling between devices must be managed separately since each diode operates independently.

Is PR3004-T suitable for capacitive-input filter designs?

No-capacitive-input filters require 20% current derating per datasheet Note 1. At full 3.0 A rating, PR3004-T is validated only for resistive or inductive loads; using it in high-C input circuits without derating risks premature failure due to elevated peak currents and thermal cycling.

Does PR3004-T meet lead-free assembly requirements?

Yes-PR3004-T features lead-free, RoHS-compliant tin-plated leads qualified per J-STD-020C Level 1 moisture sensitivity, and is approved for high-temperature reflow (260°C peak) under EU Directive Annex Note 7 exemption for lead-free soldering processes.
