Product details
Overview
BY500-600-E3/73 from Vishay General Semiconductor is a soft-recovery fast-switching plastic rectifier diode rated for 600 V repetitive peak reverse voltage, 5.0 A average forward current, and 200 ns reverse recovery time. It features low forward voltage drop (1.35 V at 5.0 A), low leakage current (10 μA at 25 °C), and high surge capability (200 A IFSM), making it suitable for medium-frequency rectification in switching-mode power supplies and freewheeling applications.
For engineers reviewing the BY500-600-E3/73 datasheet, BY500-600-E3/73 pinout, BY500-600-E3/73 application, or BY500-600-E3/73 equivalent, key selection criteria include VRRM = 600 V, trr = 200 ns, VF = 1.35 V, IR = 10 μA, and DO-201AD package compatibility with standard through-hole PCB layouts and heat-sink mounting.
Technical Context
This diode employs a single-die silicon PN junction optimized for soft recovery-minimizing voltage overshoot and EMI during turn-off in inductive switching circuits. Its 200 ns trr and 2.0 A reverse recovery current (IRM) are measured under standardized conditions (IF = 1.0 A, VR = 30 V, dI/dt = 50 A/μs).
The DO-201AD package provides a thermal resistance of 22 °C/W (junction-to-ambient, PCB-mounted on 5.0 mm × 5.0 mm copper pad), enabling reliable operation up to TJ = 125 °C with proper lead-length and heatsinking per JESD 22-B106 soldering guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in DC-blocking or flyback clamp circuits. |
| IF(AV) | 5.0 A - Average forward current at 45 °C lead temperature with 0.375" (9.5 mm) lead length; sets continuous power-handling capacity. |
| trr | 200 ns - Reverse recovery time under IF = 1.0 A, VR = 30 V, dI/dt = 50 A/μs; critical for minimizing switching losses in SMPS above ~20 kHz. |
| VF | 1.35 V - Forward voltage at 5.0 A; directly impacts conduction loss and thermal design in high-current rectification stages. |
| IR | 10 μA - Reverse leakage at 25 °C and rated VDC; ensures low standby power loss in high-impedance hold-up or sensing paths. |
| CJ | 28 pF - Junction capacitance at 4.0 V, 1 MHz; influences high-frequency noise coupling and snubber design in fast-switching nodes. |
Pinout & Package
Package: DO-201AD molded epoxy case with matte tin-plated leads; polarity indicated by cathode band; RoHS-compliant (E3 suffix), JESD 201 Class 1A whisker-tested.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node in freewheeling path). |
| Cathode | Forward current exit / reverse blocking terminal | Marked by color band; ties to output rail or positive bus; withstands up to 600 V reverse bias. |
Key Features
| Feature | Design Value |
|---|---|
| Soft recovery profile | Minimizes voltage ringing and EMI during turn-off, reducing need for snubbers in 20–100 kHz SMPS designs. |
| Low VF (1.35 V @ 5 A) | Lowers conduction loss by ~15% vs. comparable 600 V diodes with VF > 1.5 V, improving efficiency in 12–48 V output converters. |
| High IFSM (200 A) | Withstands short-duration inrush and fault currents without degradation-critical for input rectification in industrial AC-DC front-ends. |
| DO-201AD mechanical robustness | UL 94 V-0 rated epoxy body and 275 °C/10 s solder dip tolerance support automated through-hole assembly and rework reliability. |
Applications
| Switch-Mode Power Supply Rectification | Freewheeling Diode in DC Motor Drives |
|---|---|
Use Scenario: Output rectification in 50–100 kHz off-line AC-DC converters delivering 60–200 W. IC Role / Device Role / Timing Role: Main power rectifier converting high-frequency transformer secondary AC to regulated DC output. Use Value: 200 ns trr and soft recovery reduce switching loss and EMI, enabling compliance with CISPR-22 Class B limits without oversized snubbers. |
Use Scenario: Flyback path for brushed DC motor armature current during PWM turn-off. IC Role / Device Role / Timing Role: Freewheeling diode clamping inductive kickback from motor windings. Use Value: 600 V VRRM safely handles back-EMF spikes up to 400 V; 200 A IFSM absorbs transient energy during rapid deceleration. |
| Inverter DC Link Protection | Ultrasonic Generator Clamping |
Use Scenario: Reverse-polarity protection and DC link voltage clamping in 3-phase IGBT inverters for HVAC compressors. IC Role / Device Role / Timing Role: Bidirectional clamping diode across DC bus capacitors during regenerative braking events. Use Value: 125 °C max junction temperature and 22 °C/W RθJA allow stable operation under sustained 5 A conduction with minimal heatsinking. |
Use Scenario: Voltage clamping in 20–40 kHz ultrasonic transducer driver circuits. IC Role / Device Role / Timing Role: Snubberless clamp limiting resonant voltage overshoot during transducer ring-down. Use Value: Soft recovery prevents harmonic excitation of piezoelectric stack; 28 pF CJ avoids detuning of 40 kHz resonance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH5L06 | 600 V VRRM, 5 A IF(AV), but trr = 75 ns (faster), VF = 1.7 V (higher), DO-201AD package. | Better suited for >200 kHz topologies where ultra-fast recovery outweighs conduction loss penalty. | Select STTH5L06 when minimizing turn-off loss dominates over thermal budget; BY500-600-E3/73 preferred for cost-sensitive 50–100 kHz designs requiring soft recovery. |
| ES5J | 600 V VRRM, 5 A IF(AV), trr = 35 ns, VF = 1.7 V, same DO-201AD package, but not soft-recovery optimized. | Higher EMI risk in unshielded environments due to abrupt recovery; requires additional RC snubbing in sensitive audio/ultrasonic systems. | Choose ES5J only if layout includes tight EMI filtering; BY500-600-E3/73 delivers inherent noise reduction without added components. |
Compared with STTH5L06 and ES5J, BY500-600-E3/73 trades raw speed for softer switching behavior and lower VF-making it optimal for medium-frequency, thermally constrained, and EMI-sensitive applications where snubber simplicity and efficiency balance matter most.

FAQ
What is the maximum junction temperature rating for BY500-600-E3/73?
The BY500-600-E3/73 has a maximum operating junction temperature of +125 °C. This rating allows continuous operation in ambient environments up to 85 °C when mounted with 0.375" (9.5 mm) lead length and appropriate PCB copper area, as specified in the Vishay datasheet revision 26-Jul-13. Derating curves confirm 5.0 A IF(AV) is maintained at TL = 45 °C.
Is BY500-600-E3/73 suitable for automotive applications?
No, BY500-600-E3/73 is not AEC-Q101 qualified. The Vishay datasheet explicitly states "These devices are not AEC-Q101 qualified." It is intended for commercial and industrial applications such as SMPS, inverters, and motor drives where automotive-grade reliability and extended temperature validation are not required.
What does the "E3/73" suffix mean in BY500-600-E3/73?
The "E3" suffix indicates RoHS-compliant, commercial-grade construction with matte tin-plated leads meeting J-STD-002 and JESD 22-B102 solderability standards. The "/73" denotes ammo pack packaging containing 1000 units, distinct from tape-and-reel options like /54 (1400 units). Both comply with JESD 201 Class 1A whisker testing.
How does the soft recovery characteristic of BY500-600-E3/73 benefit EMI performance?
BY500-600-E3/73 exhibits soft recovery with controlled dI/dt during turn-off, reducing high-frequency voltage overshoot and ringing. This directly lowers radiated and conducted EMI in 50–100 kHz power converters-enabling simpler filter design and improved compliance with CISPR-22 without adding external snubbers that increase cost and board space.
Can BY500-600-E3/73 replace BY500-400-E3/73 in a 400 V design?
Yes, BY500-600-E3/73 can be used as a higher-voltage-rated replacement for BY500-400-E3/73 in a 400 V design, provided mechanical and thermal constraints remain unchanged. Its identical DO-201AD package, 5.0 A IF(AV), and 200 ns trr ensure functional compatibility while offering increased reverse voltage margin-though no improvement in VF, IR, or thermal resistance is gained.
