Product details
Overview
RL207-T from Diodes Incorporated is a 2.0A, 1000V peak repetitive reverse voltage general-purpose silicon rectifier diode in DO-15 package, with 1.0V max forward voltage at 2.0A DC, 70A non-repetitive surge current, and 5.0mA max reverse leakage at 25°C - used in AC/DC power supplies, input rectification stages of industrial SMPS, and offline adapter front-ends.
For engineers reviewing the RL207-T datasheet, RL207-T pinout, RL207-T application, or RL207-T equivalent, key selection criteria include peak reverse voltage rating (1000V), thermal resistance (40°C/W), junction capacitance (40pF @ 4V), derating behavior above 50°C ambient, and compatibility with wave/solder-reflow processes per MIL-STD-202 Method 208.
Technical Context
This axial-lead DO-15 rectifier operates in single-phase, half-wave configurations at 60Hz with resistive or inductive loads. Its 1000V VRRM supports high-voltage AC line inputs, while the 40°C/W θJC enables thermal management in compact PCB layouts with 9.5mm lead length.
The device exhibits 1.0V VF at IF = 2.0A DC and maintains ≤50mA IR at 125°C, supporting stable operation across industrial temperature ranges (–65°C to +150°C). Junction capacitance is 40pF at 4V reverse bias, relevant for EMI filtering and snubber design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands peak AC line transients up to 1000V in offline rectification without breakdown |
| I(AV) | 2.0 A - Sustains average forward current in continuous conduction mode at TA = 50°C with 9.5mm leads |
| VF @ 2.0A | 1.0 V - Low conduction loss reduces heat generation in 2A-class power conversion stages |
| IFSM | 70 A - Handles 8.3ms half-sine surge per JEDEC, supporting cold-start inrush in AC-DC converters |
| RθJC | 40 °C/W - Enables predictable junction-to-case thermal drop for heatsinkless designs up to ~1.5W dissipation |
| CJ @ 4V | 40 pF - Defines high-frequency reverse recovery behavior and impacts snubber component sizing |
Pinout & Package
DO-15 molded plastic package with axial leads; cathode identified by color band. Approximate weight: 0.4 g. Mounting position: any.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward current entry point | Connected to AC source or transformer secondary during positive half-cycle |
| Cathode (banded end) | Forward current exit point | Feeds filtered DC bus or bulk capacitor; polarity critical for correct rectifier orientation |
Key Features
| Feature | Design Value |
|---|---|
| UL 94V-0 rated plastic case | Meets flammability safety requirement for enclosed power supply housings |
| Low IR at 125°C (≤50 mA) | Ensures stable blocking performance in high-ambient-temperature environments like enclosed industrial enclosures |
| High IFSM/I(AV) ratio (35:1) | Provides robustness against short-duration overloads without requiring oversized devices |
| Thermal resistance RθJC = 40°C/W | Supports thermal modeling without external heatsinking in low-power (<2W) applications |
Applications
| AC-DC Power Supply Input Stage | Industrial Motor Drive Front-End |
|---|---|
Use Scenario: Rectifying 230VAC mains input before bulk capacitor filtering in open-frame 15–30W SMPS. IC Role / Device Role / Timing Role: General-purpose power rectifier handling full-wave or half-wave conduction cycles. Use Value: 1000V VRRM accommodates 230VAC + 100% surge margin; 1.0V VF limits conduction loss to <2W at 2A. | Use Scenario: Input bridge rectification in 3-phase inverter auxiliary power supply feeding gate drivers and control logic. IC Role / Device Role / Timing Role: Discrete rectifier in single-phase auxiliary winding rectifier circuit. Use Value: 70A IFSM withstands transformer inrush; DO-15 axial form factor allows through-hole mounting on high-vibration motor control PCBs. |
| LED Driver Bulk Rectification | UPS Line-Conditioning Circuit |
Use Scenario: Converting 120VAC line to DC for constant-current LED driver IC input stage in outdoor signage. IC Role / Device Role / Timing Role: Primary-side rectifier preceding PFC or buck converter stage. Use Value: UL 94V-0 case meets outdoor enclosure fire safety standards; –65°C to +150°C operating range ensures reliability in uncontrolled ambient conditions. | Use Scenario: Input rectification in online UPS systems where transient immunity and long-term stability are critical. IC Role / Device Role / Timing Role: High-reliability discrete rectifier in redundant AC input path. Use Value: 5.0mA max IR at 25°C minimizes standby power loss; 40pF CJ reduces high-frequency noise coupling into sensitive control circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 2A07G | Same DO-15 package, 1000V VRRM, but lower VF (0.95V typ), higher IFSM (80A), and improved thermal resistance (35°C/W) | Preferred for new designs requiring higher efficiency or tighter thermal margins | Select 2A07G when upgrading legacy RL207-T designs for improved conduction loss or surge robustness |
| RS2M | DO-15, 1000V VRRM, but lower I(AV) (2.0A same), higher VF (1.15V), and higher RθJC (45°C/W) | Suitable for cost-sensitive, lower-power applications where thermal headroom is available | Choose RS2M only if existing layout constraints prevent switching to newer 2A07G and thermal budget permits 0.15V higher VF |
Compared with RL207-T, 2A07G delivers measurable improvement in conduction loss and thermal performance while maintaining pin-for-pin compatibility, whereas RS2M trades off forward voltage and thermal resistance for cost - making it viable only in thermally relaxed legacy replacements.

FAQ
Is RL207-T still in active production?
No - RL207-T is officially discontinued and not recommended for new designs per Diodes Incorporated's DS28005 Rev. 7 datasheet. It remains available through authorized distributors and Aetrix Electronics for legacy system repair and continuity supply, but engineering teams should migrate to 2A07G for new projects.
What is the maximum allowable junction temperature for RL207-T?
The RL207-T has an operating junction temperature range of –65°C to +150°C. Its absolute maximum TJ is 150°C; sustained operation above this threshold risks irreversible degradation. Derating begins at TA > 50°C, with I(AV) dropping linearly to zero at ~125°C ambient (per Fig. 1).
Can RL207-T be used in full-wave bridge configurations?
Yes - RL207-T is a single die rectifier and can be used in discrete full-wave bridge configurations (e.g., four units per bridge). Its 1000V VRRM supports 400–450VDC output from 230VAC input. Ensure matched VF and thermal layout symmetry across all four devices to avoid current imbalance.
Does RL207-T meet RoHS and REACH requirements?
Yes - RL207-T complies with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, as confirmed in Diodes Incorporated's material declarations. Lead-free soldering is supported per MIL-STD-202 Method 208, and the DO-15 package contains no intentionally added restricted substances above threshold limits.
