Key Parameters

Substitute Part Grouping Explanation

Substitution of the PB805-BP is based on the following criteria derived from the provided electrical and mechanical parameters:

Mechanical Compatibility:

• Identical mounting type: Through Hole
• Identical package configuration: 4-Square, PB-10
• Identical supplier device package: PB-10

Electrical Compatibility:

• Identical diode type: Single Phase
• Identical technology: Standard
• Identical current rating: 8 A average rectified current
• Identical forward voltage characteristic: 1.1 V @ 4 A
• Identical reverse leakage current specification: 10 µA at rated voltage
• Identical operating temperature range: -55°C to 125°C

Voltage Rating Consideration: The substitute part PB810-BP features a higher peak reverse voltage rating (1 kV versus 50 V). A higher voltage rating does not prevent substitution in applications designed for the lower voltage specification, as the component will operate within its derating envelope.

Parameter Comparison

Engineering Selection Recommendations

PB810-BP Substitution Basis:

The PB810-BP is the manufacturer-recommended substitute for the obsolete PB805-BP. Both components share identical mechanical packaging (4-Square, PB-10 through-hole configuration) and core electrical characteristics (8 A rectified current, 1.1 V forward voltage, -55°C to 125°C operating range).

The PB810-BP maintains active product status with Micro Commercial Co, ensuring ongoing availability and supply chain continuity. Both parts carry identical REACH and ECCN compliance classifications (REACH Unaffected, EAR99), supporting regulatory consistency in applications.

The voltage rating differential (1 kV versus 50 V) represents an enhancement in the substitute part. Applications originally specified for 50 V operation will function within the electrical envelope of the 1 kV-rated component without performance degradation.

Frequently Asked Questions (FAQ)

Q: Can PB810-BP directly replace PB805-BP in existing circuit designs?

A: Yes. The PB810-BP maintains identical mechanical packaging (4-Square, PB-10), mounting type (through-hole), and core electrical parameters (8 A current, 1.1 V forward voltage, -55°C to 125°C operating range). The higher voltage rating (1 kV) does not prevent substitution in 50 V applications.

Q: What is the primary difference between PB805-BP and PB810-BP?

A: The peak reverse voltage rating differs: PB805-BP is rated 50 V, while PB810-BP is rated 1 kV. All other electrical and mechanical specifications are identical.

Q: Does the higher voltage rating of PB810-BP affect circuit performance?

A: No. A component with higher voltage rating operates within its derating envelope when used in lower voltage applications. The forward voltage characteristic (1.1 V @ 4 A) and reverse leakage current (10 µA) remain identical.

Q: Are there packaging or footprint differences between these parts?

A: No. Both components use identical 4-Square, PB-10 through-hole packaging and are mechanically interchangeable on PCBs designed for the PB805-BP.

Q: What is the product status difference?

A: PB805-BP is classified as obsolete, while PB810-BP maintains active product status with Micro Commercial Co, ensuring continued availability and supply chain support.

Q: Do both parts share the same compliance certifications?

A: Yes. Both PB805-BP and PB810-BP carry identical REACH Status (REACH Unaffected) and ECCN classification (EAR99).
