Product details
Overview
BY253P-E3/54 from Vishay General Semiconductor is a general-purpose plastic rectifier diode in DO-201AD package, rated for 600 V repetitive peak reverse voltage (VRRM), 3.0 A average forward current (IF(AV)), and 150 A non-repetitive surge current (IFSM), used in AC/DC power supply rectification, DC-DC converter freewheeling, and industrial inverters.
For engineers reviewing the BY253P-E3/54 datasheet, BY253P-E3/54 pinout, BY253P-E3/54 application, or BY253P-E3/54 equivalent, key selection criteria include VRRM = 600 V, VF = 1.1 V at 3.0 A, IR = 5.0 μA at rated VDC, trr = 3.0 μs, and thermal resistance RθJL = 10 °C/W - all critical for high-efficiency, thermally constrained rectifier designs.
Technical Context
This single-diode rectifier operates as an uncontrolled, silicon PN-junction device with fast recovery (trr = 3.0 μs) and low leakage (IR ≤ 5.0 μA at 600 V). Its DO-201AD package supports PCB mounting with 0.375" lead length and delivers RθJA = 20 °C/W under standard conditions.
The device exhibits a typical junction capacitance of 40 pF at 4.0 V / 1 MHz and maintains stable forward conduction up to TJ = 150 °C, enabling reliable operation in ambient temperatures from –55 °C to +150 °C without derating below 100 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse voltage before breakdown; defines safe operating limit in bridge or half-wave rectifier topologies |
| IF(AV) | 3.0 A - average forward current at 10 mm lead length; determines continuous power-handling capability in linear and switching supplies |
| IFSM | 150 A - peak surge current for 10 ms half-sine; enables robustness against inrush and transient overloads |
| VF | 1.1 V at 3.0 A - forward voltage drop; directly impacts conduction loss and thermal design in high-current paths |
| trr | 3.0 μs - reverse recovery time; limits switching frequency suitability and reduces switching losses in SMPS freewheeling |
| RθJL | 10 °C/W - thermal resistance junction-to-lead; enables accurate junction temperature estimation using lead temperature measurement |
Pinout & Package
DO-201AD molded epoxy package with axial leads; cathode indicated by color band; matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC input or switch node in freewheeling path; must withstand full IFSM during transients |
| Cathode | Forward current exit point | Marked by color band; ties to output rail or energy storage capacitor; carries full IF(AV) continuously |
Key Features
| Feature | Design Value |
|---|---|
| Low forward voltage drop | VF = 1.1 V at 3.0 A - reduces conduction loss by ~15% vs. comparable 1.25 V diodes, lowering thermal stress in compact layouts |
| Fast reverse recovery | trr = 3.0 μs - supports operation up to ~100 kHz in flyback/freewheeling applications without excessive switching loss |
| High surge robustness | IFSM = 150 A - survives repeated line surges and motor-start currents without degradation |
| Low leakage current | IR = 5.0 μA at 600 V - minimizes standby power loss in high-impedance hold-up circuits and battery-backed systems |
Applications
| AC/DC Power Supply Rectification | DC-DC Converter Freewheeling |
|---|---|
Use Scenario: Full-wave bridge rectification in offline 85–265 VAC SMPS front-end stages. IC Role / Device Role / Timing Role: Uncontrolled rectifier conducting during positive half-cycles; handles 3.0 A average load current. Use Value: 600 V VRRM ensures margin above 375 V peak line voltage; 1.1 V VF lowers heat sink requirements versus higher-VF alternatives. | Use Scenario: Freewheeling path in buck or flyback converters driving 12 V/2 A loads. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during MOSFET off-time; conducts for ~3–10 μs per cycle. Use Value: 3.0 μs trr prevents reverse recovery ringing; 150 A IFSM absorbs inductive kick from 100 μH chokes. |
| Industrial Inverter Output Stage | Uninterruptible Power Supply (UPS) Charging Circuit |
Use Scenario: Anti-parallel protection diode across IGBTs in 3-phase motor drive inverters. IC Role / Device Role / Timing Role: Clamps inductive voltage spikes during IGBT turn-off; conducts brief high-current pulses. Use Value: 150 A IFSM withstands short-circuit fault currents; DO-201AD mechanical robustness supports vibration-prone environments. | Use Scenario: AC-to-DC charging path in line-interactive UPS units with battery backup. IC Role / Device Role / Timing Role: Rectifies transformer secondary output to charge 24 V lead-acid battery bank. Use Value: 5.0 μA IR at 600 V minimizes self-discharge during long standby; UL 94 V-0 molding compound meets safety agency requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | VRRM = 600 V, IF(AV) = 3.0 A, VF = 1.15 V, trr = 45 ns - faster but higher VF and lower IFSM (80 A) | Better suited for high-frequency (>200 kHz) SMPS where ultra-fast recovery outweighs conduction loss | Select STTH3L06S only when trr < 50 ns is mandatory and thermal headroom allows higher VF |
| 1N5408G | VRRM = 1000 V, IF(AV) = 3.0 A, VF = 1.2 V, trr ≈ 2000 ns - slower, higher VF, higher VRRM | Preferred in legacy 1000 V-rated designs where cost and availability dominate over speed | Choose 1N5408G if system requires >800 V blocking and trr > 1 μs is acceptable |
Compared with STTH3L06S and 1N5408G, BY253P-E3/54 offers balanced performance: 3.0 μs trr enables mid-frequency SMPS use, 1.1 V VF improves efficiency over 1N5408G, and 150 A IFSM exceeds STTH3L06S's 80 A rating - making it optimal for cost-sensitive, thermally constrained 600 V rectifier applications.

FAQ
What is the maximum junction temperature rating for BY253P-E3/54?
The BY253P-E3/54 has a maximum junction temperature (TJ max.) of +150 °C, verified per Vishay Document Number 88838. This rating allows operation in high-ambient environments such as enclosed power supplies or motor drives, provided thermal design accounts for RθJL = 10 °C/W and RθJA = 20 °C/W. Derating begins above 100 °C ambient per Fig. 1 in the datasheet.
Is BY253P-E3/54 RoHS-compliant and lead-free?
Yes, BY253P-E3/54 is RoHS-compliant and lead-free. The "E3" suffix confirms compliance with EU RoHS Directive 2011/65/EU and JESD 201 Class 1A whisker testing. The device uses matte tin-plated leads and UL 94 V-0 molded epoxy, meeting commercial-grade environmental requirements without exemptions.
What does the "/54" suffix mean in BY253P-E3/54?
The "/54" suffix in BY253P-E3/54 indicates the preferred package code for 13-inch diameter paper tape and reel delivery, with a base quantity of 1400 units per reel. This packaging format is optimized for automated SMT placement equipment and supports high-volume manufacturing workflows.
Can BY253P-E3/54 replace BY252P-E3/54 in a 400 V design?
No, BY253P-E3/54 is not a direct replacement for BY252P-E3/54 in a 400 V design unless circuit margin allows. While both share identical IF(AV), VF, and package, BY253P-E3/54 is rated for 600 V VRRM versus 400 V for BY252P-E3/54. Substituting upward is electrically safe but may incur unnecessary cost; downward substitution risks reverse breakdown.
What is the reverse recovery time (trr) of BY253P-E3/54 and how is it measured?
The reverse recovery time (trr) of BY253P-E3/54 is 3.0 μs, measured under IF = 0.5 A, IR = 1.0 V, and Irr = 0.25 A per JEDEC test conditions. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss in high-frequency rectifier applications such as DC-DC freewheeling paths.
