Product details
Overview
SBYV27-150-E3/54 from Vishay General Semiconductor is a soft recovery ultrafast plastic rectifier diode in DO-15 package, rated for 150 V repetitive peak reverse voltage (VRRM), 2.0 A average forward current (IF(AV)), and 15 ns reverse recovery time (trr). It delivers low forward voltage drop (0.88 V at TJ = 150 °C) and low leakage (5.0 μA at 25 °C), enabling high-efficiency operation in high-frequency switching power supplies.
For engineers reviewing the SBYV27-150-E3/54 datasheet, SBYV27-150-E3/54 pinout, SBYV27-150-E3/54 application, or SBYV27-150-E3/54 equivalent, key selection criteria include ultrafast soft recovery behavior, thermal robustness up to 150 °C junction temperature, DO-15 mechanical compatibility, and RoHS-compliant matte tin-plated leads solderable per J-STD-002.
Technical Context
This device is a single silicon PN junction rectifier optimized for soft-recovery switching-minimizing voltage overshoot and EMI during turn-off in high-dI/dt environments. Its 15 ns trr is measured under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A conditions, with typical junction capacitance of 15 pF at 4.0 V and 1 MHz.
The SBYV27-150-E3/54 operates across -55 °C to +150 °C junction temperature range, features 50 A non-repetitive surge capability (IFSM), and exhibits stable forward voltage characteristics from 25 °C to 150 °C-dropping from 1.07 V to 0.88 V at 3.0 A.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling paths |
| IF(AV) | 2.0 A - average forward current at 85 °C lead temperature with 0.375" lead length; sets continuous power handling |
| trr | 15 ns - ultrafast soft recovery time; reduces switching losses and EMI in SMPS operating above 100 kHz |
| VF | 0.88 V @ 3.0 A, TJ = 150 °C - low conduction loss improves efficiency in thermally constrained designs |
| IR | 5.0 μA @ VR = 150 V, TA = 25 °C - low leakage preserves regulation in high-impedance hold-up circuits |
| TJ max. | +150 °C - extended junction temperature rating supports compact PCB layouts without derating penalties |
| RθJA | 45 °C/W - thermal resistance from junction to ambient (0.375" lead length); informs heatsinking requirements |

Applications
| Switch-Mode Power Supply Output Rectification | DC-DC Converter Freewheeling Diode |
|---|---|
Use Scenario: Secondary-side rectification in 100–500 kHz isolated flyback or forward converters powering servers or telecom equipment. IC Role / Device Role / Timing Role: Unidirectional current path delivering regulated DC output; recovers softly to suppress snubber losses. Use Value: 15 ns trr and 0.88 V VF reduce conduction and switching losses, improving full-load efficiency by ≥0.5% versus standard fast recovery diodes. | Use Scenario: Freewheeling path in synchronous or non-synchronous buck converters for FPGA core voltage rails. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during high-side switch off-time; soft recovery avoids gate drive coupling. Use Value: Low 5.0 μA IR at 25 °C maintains tight output regulation during light-load burst-mode operation. |
| Inverter Auxiliary Power Supply | Industrial Motor Drive Snubber Network |
Use Scenario: Auxiliary 24 V supply derived from main DC bus in variable-frequency drives using transformer-coupled flyback. IC Role / Device Role / Timing Role: High-frequency rectifier in self-powered auxiliary converter; operates continuously at 125 °C ambient. Use Value: +150 °C TJ max. and 45 °C/W RθJA allow reliable operation without forced air, reducing system BOM cost. | Use Scenario: RC snubber clamp diode across IGBTs in 3-phase motor inverters switching at 8–15 kHz. IC Role / Device Role / Timing Role: Absorbs inductive energy during IGBT turn-off; soft recovery prevents voltage spikes exceeding 600 V bus. Use Value: 15 ns trr with controlled tail current limits dV/dt stress on IGBT gate oxide and reduces snubber capacitor size by 30%. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ultrafast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R015DJF | TO-277A package (surface-mount), 150 V VRRM, 2.0 A IF(AV), trr = 18 ns, VF = 0.92 V @ 2 A | Requires rework of through-hole footprint; better suited for space-constrained SMT designs | Select when board area is limited and reflow compatibility is required |
| ES2DA | SMA package, 200 V VRRM, 2.0 A IF(AV), trr = 35 ns, VF = 0.95 V @ 2 A | Slower recovery increases switching loss in >200 kHz designs; higher VRRM allows wider input range | Choose only if 200 V blocking margin is critical and frequency ≤150 kHz |
Compared with STTH2R015DJF and ES2DA, the SBYV27-150-E3/54 offers the fastest recovery (15 ns) in a legacy-compatible DO-15 through-hole package, making it optimal for retrofitting or cost-sensitive high-volume power supplies where layout change is prohibitive.

The SBYV27-150-E3/54 has a maximum junction temperature (TJ max.) of +150 °C, verified per Vishay Document Number 88736. This rating allows sustained operation in thermally demanding environments such as enclosed power supplies or motor drive auxiliary circuits without mandatory heatsinking, provided RθJA and power dissipation remain within derating curves.
Does the SBYV27-150-E3/54 have a soft recovery characteristic, and why does it matter?
Yes, the SBYV27-150-E3/54 is explicitly characterized as a soft recovery ultrafast rectifier. Its controlled reverse recovery minimizes voltage overshoot and electromagnetic interference during turn-off-critical in high-dI/dt topologies like flyback and resonant converters. This behavior directly reduces snubber losses and simplifies EMI filter design compared to hard-recovery alternatives.
What is the reverse recovery time (trr) specification for the SBYV27-150-E3/54, and under what conditions is it measured?
The SBYV27-150-E3/54 has a maximum reverse recovery time (trr) of 15 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per Vishay Document Number 88736. These standardized test conditions ensure consistent comparison across ultrafast diodes and reflect real-world performance in high-frequency switching nodes.
Is the SBYV27-150-E3/54 RoHS-compliant and qualified for automated assembly?
Yes, the SBYV27-150-E3/54 carries the E3 suffix, confirming RoHS compliance and qualification to JESD 201 Class 1A whisker testing. Its matte tin-plated leads meet J-STD-002 solderability standards, supporting reliable wave and selective soldering in high-volume manufacturing without lead finish degradation.
What package type does the SBYV27-150-E3/54 use, and what are its key mechanical features?
The SBYV27-150-E3/54 uses the DO-15 (DO-204AC) axial-leaded package with 0.300" ±0.070" body length and 0.034" ±0.005" lead diameter. It features UL 94 V-0 flammability-rated molding compound, cathode polarity marked by a color band, and lead finish compatible with standard PCB hole sizes and IPC-A-610 Class 2/3 assembly requirements.
