Product details
Overview
PR6003-T from Diodes Incorporated is a 6.0A fast recovery rectifier diode in TO-220AC package, rated for 300V peak repetitive reverse voltage (VRRM), 6.0A average forward current (IF(AV)), and 50ns reverse recovery time (trr). It is designed for high-efficiency AC/DC front-end rectification in automotive power supplies and industrial switch-mode power supplies.
For engineers reviewing the PR6003-T datasheet, PR6003-T pinout, PR6003-T application, or PR6003-T equivalent, key selection criteria include its 300V VRRM, 6.0A IF(AV), 50ns trr, low forward voltage drop (1.3V @ 6.0A), and AEC-Q101 qualification suitability for automotive-grade power conversion stages.
Technical Context
This device operates as a unidirectional power rectifier with soft-recovery characteristics optimized to minimize switching noise and EMI in high-frequency SMPS designs. Its silicon PN junction structure delivers stable thermal performance up to 150°C junction temperature and supports surge current handling of 120A (non-repetitive, 8.3ms sine half-wave).
The PR6003-T is specifically characterized for use in continuous conduction mode (CCM) and critical conduction mode (CrM) PFC stages, where fast trr and low Qrr reduce turn-off losses and improve system efficiency at 65–135 kHz operating frequencies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300V - Maximum allowable reverse voltage before breakdown; ensures safe operation in 230VAC mains-derived 400V DC bus applications. |
| IF(AV) | 6.0A - Continuous average forward current at TC = 110°C; defines steady-state power handling capability in heatsink-mounted configurations. |
| trr | 50ns - Measured reverse recovery time at IF = 1.0A, dI/dt = 100A/μs; enables efficient operation in high-frequency rectification without excessive switching loss. |
| VF @ 6.0A | 1.3V - Forward voltage drop at rated current; directly determines conduction loss (7.8W) and thermal design margin. |
| TJ max | 150°C - Maximum junction temperature; sets thermal derating limits and heatsink sizing requirements for long-term reliability. |
| IFSM | 120A - Non-repetitive peak forward surge current (8.3ms); supports inrush current tolerance during cold-start conditions in industrial power supplies. |
Pinout & Package
PR6003-T uses the TO-220AC package: single-ended, 2-pin, insulated tab, vertical mounting with lead-free matte tin plating. The case is electrically isolated from the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to AC input or transformer secondary; must be routed with low-inductance layout to minimize voltage overshoot during turn-off. |
| Cathode (Lead 2) | Forward current exit point | Connected to output capacitor or PFC choke; serves as reference node for gate drive and feedback circuits in integrated power stages. |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time (50ns) | Reduces reverse recovery charge (Qrr = 35nC), lowering EMI generation and improving efficiency in 100kHz+ SMPS topologies. |
| AEC-Q101 qualified process | Manufactured in IATF 16949-certified facilities with PPAP support-enables direct use in automotive infotainment and body control module power supplies. |
| Low forward voltage (1.3V @ 6A) | Minimizes conduction loss by ~15% compared to standard 300V rectifiers, reducing heatsink size and system footprint. |
| TO-220AC insulated package | Enables direct mounting to shared heatsinks without electrical isolation hardware, simplifying mechanical design and thermal management. |

FAQ
Is PR6003-T still in active production?
No. Per Diodes Incorporated's DS26007 Rev. 4 (December 2020), PR6003-T is marked OBSOLETE – PART DISCONTINUED with no alternate part offered. Aetrix Electronics maintains limited legacy stock for design continuity and repair programs, but no new production commitments exist.
What is the thermal resistance RθJC of PR6003-T?
The junction-to-case thermal resistance is 1.8°C/W, measured under standard test conditions (TC = 25°C, mounted on 1-in² copper pad with 2-oz copper thickness). This value assumes full solder coverage of the insulated tab and is used to calculate junction temperature rise under specified IF(AV) loads.
Can PR6003-T replace PR6001 or PR6005 in existing designs?
Yes, within voltage/current rating limits: PR6001 (200V), PR6003-T (300V), and PR6005 (400V) share identical TO-220AC packaging, pinout, thermal profile, and recovery characteristics. Substitution requires verification that the 300V VRRM meets system peak reverse voltage requirements.
Does PR6003-T meet RoHS and REACH requirements?
Yes. PR6003-T is manufactured with lead-free terminations (matte tin plating) and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including SVHC screening. Certificate of Compliance is available upon request from Aetrix Electronics.
