Product details
Overview
BY255GPHE3/73 from Vishay General Semiconductor is a glass-passivated junction plastic rectifier diode in DO-201AD package, rated for 1300 V repetitive peak reverse voltage (VRRM), 3.0 A average forward current (IF(AV)), and 100 A non-repetitive surge current (IFSM), used as a freewheeling or output rectifier in high-voltage AC/DC converters and inverters.
For engineers reviewing the BY255GPHE3/73 datasheet, BY255GPHE3/73 pinout, BY255GPHE3/73 application, or BY255GPHE3/73 equivalent, key selection criteria include its 1300 V blocking capability, 1.1 V forward voltage at 3.0 A, 5.0 μA reverse leakage at rated voltage, 3.0 μs reverse recovery time, and DO-201AD mechanical compatibility with high-temperature PCB mounting.
Technical Context
This device implements a single-die Superectifier® structure with cavity-free glass passivation, enabling stable operation up to 175 °C junction temperature and low IR drift over temperature. Its fast 3.0 μs trr and 40 pF junction capacitance support switching applications requiring reduced switching losses and EMI control.
The DO-201AD package provides UL 94 V-0 flammability rating, matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, and meets JESD 201 Class 1A whisker resistance. Thermal resistance is 20 °C/W (junction-to-ambient) and 10 °C/W (junction-to-lead) at 9.5 mm lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1300 V - supports primary-side rectification in 1 kV-class offline SMPS and industrial DC link circuits |
| IF(AV) | 3.0 A - continuous conduction mode operation with 10 mm lead length at 55 °C ambient |
| VF @ 3.0 A | 1.1 V - low conduction loss enabling >85 % efficiency in medium-power rectifier stages |
| IR @ VDC | 5.0 μA - minimal leakage under full 1300 V DC blocking, critical for high-impedance hold-up networks |
| trr | 3.0 μs - fast recovery reduces switching node ringing and improves EMI performance in 50–100 kHz converters |
| TJ max. | 175 °C - enables reliable operation in sealed enclosures or high-ambient industrial environments |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600 V VRRM, 3.0 A IF(AV), TO-220AC package, 50 ns trr | Limited to ≤600 V systems; requires heatsink due to higher thermal resistance | Select when lower voltage rating suffices and board space allows TO-220 mounting |
| ES3J-E3/57T | 600 V VRRM, 3.0 A IF(AV), DO-204AL (SMA) package, 35 ns trr | Lower voltage rating and smaller package limit surge handling and thermal mass | Prefer for compact consumer adapters where 1300 V margin is unnecessary |
Compared with STTH3L06S and ES3J-E3/57T, the BY255GPHE3/73 delivers unique 1300 V blocking capability in a surface-mount-compatible DO-201AD package with proven 100 A surge resilience-critical for industrial and renewable energy systems where overvoltage transients exceed 1 kV.

FAQ
What is the maximum junction temperature rating for BY255GPHE3/73?
The BY255GPHE3/73 has a maximum junction temperature (TJ max.) of +175 °C, verified per Vishay Document Number 88541. This rating enables operation in sealed industrial enclosures or high-ambient environments where thermal dissipation is constrained. Derating curves in the datasheet define safe IF(AV) limits above 55 °C ambient, and the DO-201AD package's RθJA of 20 °C/W must be considered in layout design. The BY255GPHE3/73 maintains specified electrical parameters within this full temperature range.
Is BY255GPHE3/73 RoHS-compliant and lead-free?
Yes, the BY255GPHE3/73 is RoHS-compliant and lead-free, as confirmed by the "E3" suffix in its part number and Vishay's material categorization documentation (www.vishay.com/doc?99912). Its matte tin-plated leads meet J-STD-002 solderability requirements, and the device passes JESD 201 Class 1A whisker testing. The DO-201AD molding compound complies with UL 94 V-0 flammability standards, and no exemptions apply to its RoHS status.
What does the "HE3/73" suffix indicate in BY255GPHE3/73?
The "HE3/73" suffix denotes Vishay's packaging and compliance coding: "E3" specifies RoHS-compliant, commercial-grade construction with matte tin leads; "73" identifies ammo pack packaging with a base quantity of 1000 units. This differs from "/54", which indicates 13-inch paper tape and reel (1400 units). The core die and electrical specifications of BY255GPHE3/73 remain identical across all suffix variants-only packaging and test grading differ.
How does the reverse recovery time of BY255GPHE3/73 compare to standard rectifiers?
The BY255GPHE3/73 has a typical reverse recovery time (trr) of 3.0 μs under IF = 0.5 A, IR = 1.0 V, and Irr = 0.25 A conditions-significantly faster than general-purpose rectifiers (often >10 μs) but slower than ultrafast or Schottky types. This value balances low leakage and high voltage capability, making it suitable for 50–100 kHz switch-mode applications where excessive trr causes switching losses and EMI. The BY255GPHE3/73 achieves this via optimized Superectifier® doping and cavity-free passivation.
Can BY255GPHE3/73 replace BY254GPHE3/73 in a design?
Yes, the BY255GPHE3/73 can directly replace BY254GPHE3/73 in most designs because both share identical DO-201AD package, pinout, thermal characteristics, and forward conduction specs (3.0 A IF(AV), 1.1 V VF). The only difference is reverse voltage rating: BY254GPHE3/73 is rated for 800 V VRRM, while BY255GPHE3/73 is rated for 1300 V. Using BY255GPHE3/73 provides increased voltage margin but may incur slightly higher cost; no PCB or layout changes are required for substitution.
