Product details
Overview
DSR15V600 from Diodes Incorporated is a 15A, 600V ultra-fast recovery silicon rectifier diode in TO220AC package, featuring trr < 30ns, soft recovery (S = 1.0 @ 25°C), and 140A non-repetitive surge capability. It serves as the boost diode in active PFC stages of AC-DC power supplies for telecom and industrial SMPS.
For engineers reviewing the DSR15V600 datasheet, DSR15V600 pinout, DSR15V600 application, or DSR15V600 equivalent, key selection criteria include reverse recovery time, softness factor, thermal resistance (2°C/W), forward voltage at 15A, and junction capacitance at 4V - all critical for EMI-limited high-frequency PFC designs.
Technical Context
This diode employs Diodes Inc.'s proprietary DIODESTAR™ process to achieve ultra-fast (trr = 23–30 ns) and soft reverse recovery with low EMI generation. Its softness factor of 1.0 at 25°C and 0.6 at 125°C ensures controlled turn-off behavior under varying thermal conditions.
The device delivers 15A average forward current with 2°C/W junction-to-case thermal resistance and supports 600V peak repetitive reverse voltage. Its 80pF junction capacitance at 4V/1MHz and 256nC Qrr at 125°C directly impact switching loss and snubber design in 100–300kHz PFC circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Withstands peak line transients in universal-input (85–265VAC) PFC front-ends without avalanche breakdown. |
| IF(AV) | 15 A - Sustains continuous conduction in 500W+ boost PFC stages with derating above 125°C case temperature. |
| trr | 23–30 ns - Enables operation up to 300kHz switching frequency while limiting diode-induced switching losses. |
| VF @ 15A | ≤3.2 V - Contributes ~48W conduction loss at full load; requires heatsinking per 2°C/W RθJC spec. |
| Qrr | 87 nC (25°C) / 256 nC (125°C) - Directly determines turn-on loss in the following switch; higher Qrr at elevated Tj increases crossover loss. |
| S (Softness) | 1.0 @ 25°C, 0.6 @ 125°C - Lower softness at high temperature reduces dI/dt-induced voltage overshoot but increases EMI risk. |
| RθJC | 2 °C/W - Allows direct mounting to heatsink; 30W dissipation raises junction temp by only 60°C above case. |
Pinout & Package
Package: TO220AC - 3-lead molded plastic case (UL 94V-0), matte tin-plated copper leadframe, designed for vertical mounting with tab isolation. Thermal path optimized via metal tab (cathode-connected) for heatsink attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Input terminal for AC or switched node | Connects to boost inductor output; carries full AC-line-frequency and high-frequency ripple current. |
| 2 (Cathode) | Output terminal / Heat sink interface | Electrically tied to metal tab; must be isolated from chassis unless system ground referenced; primary thermal path. |
| 3 (Cathode) | Redundant cathode connection | Parallel cathode path to reduce series inductance and improve current sharing in high-di/dt PFC operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast recovery (trr ≤30ns) | Enables high-frequency PFC operation (>200kHz) with minimized reverse recovery loss and reduced snubber stress. |
| Soft recovery (S = 1.0 @ 25°C) | Suppresses high-frequency ringing and conducted EMI during turn-off, easing EMC filter design. |
| High surge rating (IFSM = 140A) | Withstands inrush and overload transients in 500–1000W server/industrial PSUs without degradation. |
| Low RθJC (2°C/W) | Permits compact thermal design: 30W dissipation raises junction temperature only 60°C above heatsink surface. |
| RoHS-compliant, lead-free finish | Meets EU Directive 2002/95/EC with applicable exemptions; compatible with standard Pb-free reflow profiles. |
Applications
| Telecom Rectification | Industrial SMPS |
|---|---|
Use Scenario: Front-end rectification and PFC stage in 48V telecom rectifiers (e.g., -48V DC output systems). IC Role / Device Role / Timing Role: Boost diode in continuous conduction mode (CCM) PFC controller IC-based topology. Use Value: 23ns trr and soft recovery reduce EMI emissions below CISPR-22 Class B limits without oversized filters. | Use Scenario: Input rectification and PFC in programmable logic controller (PLC) power modules rated for 24/48/110VDC input. IC Role / Device Role / Timing Role: High-reliability output diode in dual-stage (bridge + boost) AC-DC conversion. Use Value: 140A IFSM withstands motor drive startup surges; 175°C max TJ supports operation in sealed industrial enclosures. |
| Server Power Supply | Medical AC-DC Adapters |
Use Scenario: Primary-side boost diode in 80 PLUS Titanium-certified 1kW server PSUs operating at 250kHz. IC Role / Device Role / Timing Role: Critical conduction path in interleaved PFC with synchronous rectification downstream. Use Value: 80pF CJ minimizes capacitive coupling noise into control ICs; 2°C/W RθJC enables fanless thermal design at 75% load. | Use Scenario: Input rectifier in IEC 60601-1 compliant medical AC-DC adapters (Class II, 2×MOPP). IC Role / Device Role / Timing Role: Isolation barrier diode in double-insulated, low-leakage (<50µA) front-end stage. Use Value: 50µA IR at 600V ensures compliance with patient leakage current limits even at end-of-life aging. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast recovery diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1606D | 16A/600V, trr = 35ns, RθJC = 2.5°C/W, VF = 2.9V @ 16A | Higher VF improves conduction efficiency but slower trr increases switching loss above 200kHz | Preferable where thermal margin >10°C exists and EMI filtering is less constrained |
| IXYS MUR1560 | 15A/600V, trr = 50ns, RθJC = 2.2°C/W, VF = 2.7V @ 15A | Lower VF reduces conduction loss but significantly higher trr degrades high-frequency PFC efficiency | Acceptable in 65–100kHz PFC designs where cost sensitivity outweighs EMI performance |
Compared with STTH1606D and IXYS MUR1560, DSR15V600 offers the fastest recovery (23ns) and softest turn-off for minimal EMI - critical in dense, high-frequency PFC layouts - while trading 0.3–0.5V higher VF for superior noise control and thermal predictability.

FAQ
Is DSR15V600 still in active production?
No - Diodes Incorporated officially discontinued DSR15V600 (as noted in DS35012 Rev. 5-2, October 2013). However, Aetrix Electronics maintains legacy inventory with full traceability and provides extended lifecycle support, including cross-reference assistance and obsolescence mitigation planning for ongoing production programs.
What is the correct pin configuration for TO220AC mounting?
When viewed with leads facing down and tab upright, pin 1 (anode) is leftmost, pin 2 (cathode/tab) is center, and pin 3 (cathode) is rightmost. The metal tab is electrically connected to both cathode pins and must be electrically isolated from the heatsink unless system grounding architecture explicitly permits it.
How does softness factor affect EMI in PFC designs?
A softness factor (S) near 1.0 indicates gradual current decay during turn-off, reducing di/dt-induced voltage spikes and high-frequency ringing. At 25°C, DSR15V600's S = 1.0 suppresses >100MHz EMI peaks; at 125°C, S drops to 0.6, increasing edge sharpness and requiring tighter snubber tuning in thermally stressed operation.
Can DSR15V600 replace standard FR157 or UF156 diodes?
No - DSR15V600 is not a drop-in replacement for FR157 (1A/1000V) or UF156 (15A/600V). While voltage/current ratings overlap, its DIODESTAR™ process delivers 3× faster trr (23ns vs. ~75ns) and soft recovery absent in those parts. Substitution requires layout review for reduced snubber energy and EMI filter adjustments.
