P0722SBRP Equivalent & Substitute Parts

Part Overview

The P0722SBRP is a 65V Off-State, 250A Peak Pulse TVS Thyristor in DO-214AA (SMB) surface mount package, manufactured by Littelfuse Inc. as part of the TwinChip™ series. This component is classified as Obsolete, indicating discontinuation from the manufacturer. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for applications utilizing this transient voltage suppression device.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for TVS thyristors is determined by the following critical parameters: Off-State Voltage, Package/Case type, Mounting configuration, and Peak Pulse Current capability. The P0722SBRP operates at 65V Off-State with a 250A peak pulse rating in DO-214AA SMB packaging.

Two substitute paths are identified:

Direct Equivalent (Same Manufacturer): P0722SBLRP maintains identical electrical specifications (65V Off-State, 250A peak pulse, 8V On-State, 120mA hold current) and package format. The primary distinction is packaging configuration (Tape & Reel versus bulk) and active product status with ROHS3 compliance.

Cross-Manufacturer Substitute (STMicroelectronics): SMP100LC-65 operates at the same 65V Off-State voltage and DO-214AA SMB package but provides enhanced current handling (400A peak pulse versus 250A) with higher hold current (150mA versus 120mA). This represents a performance upgrade within the same voltage class and package footprint.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: P0722SBLRP is the preferred substitute when maintaining exact electrical specifications is required. This part is manufactured by the same supplier, carries Active product status, and achieves ROHS3 compliance. The electrical parameters are identical to the obsolete P0722SBRP, ensuring functional equivalence in existing circuit designs.

For Performance-Enhanced Applications: SMP100LC-65 is suitable when circuit design permits higher current handling and increased hold current. This cross-manufacturer option provides superior transient suppression capability (400A versus 250A peak pulse) within the same voltage class and package footprint. Both substitute options maintain ROHS3 compliance and Active product status, supporting long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can P0722SBLRP be used as a direct drop-in replacement for P0722SBRP?

A: Yes. P0722SBLRP maintains identical electrical specifications including 65V Off-State voltage, 250A peak pulse current, 8V On-State voltage, and 120mA hold current. Both components use DO-214AA SMB packaging and surface mount configuration. The primary difference is packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Q: What are the key differences between P0722SBLRP and SMP100LC-65?

A: Both operate at 65V Off-State in DO-214AA SMB packages. SMP100LC-65 provides higher peak pulse current (400A versus 250A), increased hold current (150mA versus 120mA), and higher capacitance (90pF versus 45pF). SMP100LC-65 contains a single element versus two elements in the Littelfuse parts. Breakover voltage differs slightly (85V versus 88V).

Q: Are all substitute parts RoHS compliant?

A: P0722SBRP is RoHS non-compliant. Both P0722SBLRP and SMP100LC-65 are ROHS3 compliant, meeting current environmental regulations for new designs and production.

Q: Does package format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) packaging formats do not alter electrical characteristics. Packaging selection is determined by manufacturing and assembly process requirements, not circuit performance.

Q: Can SMP100LC-65 be used in applications designed for P0722SBRP?

A: SMP100LC-65 is electrically compatible at the 65V Off-State voltage level and uses identical DO-214AA SMB packaging. The higher current rating (400A versus 250A) and increased hold current (150mA versus 120mA) represent performance enhancements. Circuit design must accommodate the 3V lower breakover voltage (85V versus 88V) and higher capacitance (90pF versus 45pF) if these parameters are critical to application performance.
