Product details

Overview

PR1005-T from Diodes Incorporated is a 1.0A fast recovery rectifier diode in DO-41 package, rated for 600V peak repetitive reverse voltage (V_RRM), 1.2V forward voltage drop at 1.0A (V_FM), and 150ns reverse recovery time (t_RR), used in AC/DC input stage rectification for offline switch-mode power supplies.

For engineers reviewing the PR1005-T datasheet, PR1005-T pinout, PR1005-T application, or PR1005-T equivalent, key selection criteria include V_RRM derating margin, thermal resistance (R_θJA = 75°C/W), surge capability (I_FSM = 30A), low IRM (5.0µA @ 25°C), and DO-41 mechanical compatibility with through-hole PCB layouts.

Technical Context

This device employs a diffused junction structure to achieve fast switching performance and low conduction loss. Its 150ns reverse recovery time enables efficient operation in 50/60Hz and higher-frequency rectification circuits up to ~20kHz without excessive switching loss or EMI generation.

The DO-41 molded plastic case provides UL 94V-0 flammability rating and supports lead-free soldering per MIL-STD-202 Method 208. Cathode band polarity marking and tin-plated leads ensure reliable assembly and unambiguous orientation during manual or automated insertion.

Key Specifications

V_RRM	600V - Withstands peak line transients in 230VAC mains applications with ≥2× safety margin.
I_O	1.0A @ T_A = +75°C - Sustains continuous output current in compact heatsinkless designs.
V_FM	1.2V @ I_F = 1.0A - Minimizes conduction loss and thermal rise in high-duty-cycle rectifiers.
t_RR	150ns - Reduces switching loss and ringing in flyback and forward converter input stages.
I_FSM	30A (8.3ms half-sine) - Survives cold-start inrush and lightning-induced surges without failure.
R_θJA	75°C/W - Enables thermal design with minimal copper area; ΔT ≈ 75°C at full load in still air.
I_RM	5.0µA @ 25°C - Limits standby power loss in energy-efficient adapters and LED drivers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
RS1J-T	V_RRM = 600V, t_RR = 500ns, V_FM = 1.3V, same DO-41 package	Slower recovery increases switching loss in high-frequency designs; suitable only for 50/60Hz linear supplies	Select RS1J-T only if cost sensitivity outweighs efficiency targets and layout allows larger snubbers.
UF4007	V_RRM = 1000V, t_RR = 75ns, V_FM = 1.7V, DO-41 package	Higher V_RRM and faster t_RR improve surge margin and high-frequency performance but increase conduction loss	Choose UF4007 when designing for 305VAC nominal input or >100kHz operation where lower Q_rr is critical.

Compared with RS1J-T, PR1005-T delivers 3.3× faster recovery for reduced EMI and loss in SMPS; versus UF4007, it trades 400V extra blocking margin and 0.5V higher V_FM for lower cost and better thermal efficiency at 1.0A.

FAQ

What is the maximum allowable junction temperature for PR1005-T?

The absolute maximum junction temperature (T_J) is +150°C, with continuous operation permitted from –65°C to +150°C. Derating begins at +75°C ambient for the 1.0A average current rating, and thermal design must ensure T_J remains below 150°C under worst-case load and ambient conditions.

Can PR1005-T be used in surface-mount designs?

No - PR1005-T uses the axial DO-41 package with leads intended for through-hole mounting. It lacks SMD-compatible terminations or footprint geometry. For surface-mount equivalents, consider Diodes Inc.'s AP1005W (SMA) or SB1060 (SMB) series with matching 600V/1A ratings.

Is PR1005-T compliant with halogen-free and antimony-free standards?

Yes - PR1005-T meets Diodes Incorporated's "Green" definition: halogen-free (≤900ppm Cl, ≤900ppm Br, ≤1500ppm total halogens) and antimony-free (≤500ppm), as verified per IEC 61249-2-21 and JEDEC J-STD-70B standards.

How does PR1005-T compare to PR1004-T in terms of voltage rating and use cases?

PR1005-T has V_RRM = 600V versus PR1004-T's 400V, making it suitable for 230VAC systems with tighter safety margins and higher transient immunity. PR1004-T is adequate for 115VAC-only designs or dual-voltage supplies with automatic range switching, while PR1005-T eliminates redesign risk in global-input products.
