Product details

Overview

1N4005-T from Diodes Incorporated is a general-purpose silicon rectifier diode in DO-41 package, rated for 600 V peak repetitive reverse voltage, 1.0 A average forward current, and 30 A non-repetitive surge current. It features low forward voltage drop (1.0 V at 1.0 A), low reverse leakage (5.0 µA at 25°C), and is RoHS-compliant with bright tin-plated leads for reliable solderability in AC/DC power supply front-end rectification.

For engineers reviewing the 1N4005-T datasheet, 1N4005-T pinout, 1N4005-T application, or 1N4005-T equivalent, key selection criteria include its 600 V blocking capability, thermal resistance (100 °C/W), junction capacitance (8 pF at 4 V), operating temperature range (–65 to +150 °C), and compatibility with half-wave and full-wave bridge configurations in industrial and consumer power supplies.

Technical Context

The 1N4005-T implements a diffused P-N junction optimized for high-current rectification with low conduction loss. Its 600 V V_RRM rating enables use in 400 VAC line-derived supplies after derating, while the 30 A I_FSM supports transient surge immunity per IEC 61000-4-5 Level 3.

Junction capacitance of 8 pF at 4 V and 1 MHz limits high-frequency switching suitability but ensures stable performance in 50/60 Hz applications. Thermal design relies on ambient-conducted heat dissipation via axial leads, with derating required above +75°C ambient per Fig. 1.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Supports rectification of up to ~424 V peak AC input before derating.
I_O	1.0 A @ T_A = +75°C - Continuous DC output current capability under standard heatsinking conditions.
V_F	1.0 V @ I_F = 1.0 A - Low conduction loss reduces power dissipation and thermal stress in linear power stages.
I_FSM	30 A (8.3 ms half-sine) - Withstands typical AC line surge events without failure.
I_R	5.0 µA @ 25°C - Ensures minimal standby power loss in off-state blocking applications.
C_j	8 pF @ 4 V, 1 MHz - Low junction capacitance minimizes capacitive coupling noise in low-speed rectifiers.
R_θJA	100 °C/W - Defines thermal rise from junction to ambient under free-air conditions with 9.5 mm lead length.

Applications

AC/DC Power Supply Input Rectification

DC Power Rail Protection

Use Scenario: Half-wave or full-wave bridge rectification of 120/230 VAC mains in offline switch-mode or linear power supplies.

IC Role / Device Role / Timing Role: Primary rectifying element converting AC input to pulsating DC prior to filtering and regulation.

Use Value: 600 V V_RRM provides 50% margin over 400 V peak line voltage, ensuring safe operation under brownout and surge conditions.

Use Scenario: Reverse-polarity protection on 12–48 V DC input rails for embedded controllers and sensor modules.

IC Role / Device Role / Timing Role: Series-blocking diode preventing damage from accidental battery or adapter reversal.

Use Value: 1.0 V forward drop balances protection integrity with minimal voltage loss in low-voltage systems.

Capacitor-Input Filter Stage

Inductive Load Freewheeling

Use Scenario: Output rectification in capacitor-input filter designs for low-noise analog power rails.

IC Role / Device Role / Timing Role: Isolates rectified output from transformer during capacitor recharge intervals.

Use Value: Low 5.0 µA reverse leakage preserves hold-up time and minimizes standby power drain.

Use Scenario: Freewheeling path for relay coils, solenoids, and DC motor back-EMF suppression.

IC Role / Device Role / Timing Role: Clamps inductive kickback voltage to safe levels during switch-off transitions.

Use Value: 30 A I_FSM safely absorbs energy from typical 24 V/1 A inductive loads without degradation.

Equivalent & Alternatives

The following parts are listed as comparable options for similar general-purpose rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4005G (ON Semiconductor)	Identical V_RRM, I_O, and V_F; same DO-41 package; AEC-Q200 qualified variant available.	Preferred for automotive-grade designs requiring PPAP documentation and IATF 16949 traceability.	Select when automotive qualification or alternate sourcing diversity is required.
RS1M (Fairchild/ON)	Same 600 V V_RRM and 1.0 A I_O, but faster recovery (500 ns vs. >2 µs) and lower C_j (5 pF).	Better suited for higher-frequency rectification (e.g., 20 kHz SMPS secondaries) where switching loss matters.	Choose only if reduced reverse recovery time is critical; not drop-in for 50/60 Hz mains rectification.

Compared with 1N4005G and RS1M, the 1N4005-T offers optimal cost-performance balance for standard 50/60 Hz rectification, with superior surge robustness versus RS1M and broader commercial availability than AEC-Q200 variants.

FAQ

What is the maximum junction temperature for the 1N4005-T?

The 1N4005-T has a maximum junction temperature (T_J) of +150°C, with an operating and storage temperature range from –65°C to +150°C. This allows reliable operation in enclosed industrial enclosures or near heat-generating components when ambient temperatures remain within specification limits and thermal derating is applied above +75°C ambient.

Is the 1N4005-T suitable for use in a full-wave bridge configuration?

Yes - the 1N4005-T is commonly used in discrete full-wave bridge rectifiers due to its 600 V V_RRM, 1.0 A I_O, and robust surge rating. Four units can form a 600 V, 1.0 A bridge; however, total power dissipation must be managed across all devices, and layout should ensure symmetrical thermal paths to avoid localized overheating.

Does the 1N4005-T have lead-free and RoHS-compliant construction?

Yes - the 1N4005-T features a lead-free finish and complies with EU RoHS Directives 2002/95/EC, 2011/65/EU, and 2015/863/EU. Its terminals are bright tin-plated, and the molded plastic package meets UL 94V-0 flammability rating, supporting environmentally regulated product certifications.

Why does the datasheet state "NOT RECOMMENDED FOR NEW DESIGNS"?

Diodes Incorporated issued this notice because newer alternatives (e.g., higher-efficiency fast recovery or Schottky rectifiers) offer improved performance in modern power supplies. However, the 1N4005-T remains fully manufactured, stocked, and supported for legacy repair, cost-driven applications, and designs where its proven reliability and surge tolerance outweigh efficiency gains.
