SJPZ-N33VR Equivalent & Substitute Parts

Part Overview

The SJPZ-N33VR is a Zener transient voltage suppressor (TVS) diode manufactured by Sanken Electric USA Inc., designed for surface mount applications in automotive-grade circuits. This component provides transient voltage protection with a 33V breakdown voltage rating and 500W peak pulse power capability. The part is currently in active production status with AEC-Q101 automotive qualification. Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and qualification standards are maintained across the same product series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SJPZ-N33VR is determined by strict equivalence across the following critical parameters:

• Voltage - Breakdown (Min): 31V
• Power - Peak Pulse: 500W
• Unidirectional Channels: 1
• Package / Case: 2-SMD, J-Lead
• Supplier Device Package: SJP
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Grade: Automotive
• Qualification: AEC-Q101
• Mounting Type: Surface Mount
• RoHS Status: RoHS Compliant

The SJPZ-N33VL qualifies as a direct substitute because it maintains identical electrical ratings, mechanical packaging, automotive qualification, and environmental compliance specifications. Both parts belong to the SJPZ-N series and share the same base product number (SJPZ-N33).

Parameter Comparison

Engineering Selection Recommendations

Both the SJPZ-N33VR and SJPZ-N33VL are active production components with identical AEC-Q101 automotive qualification and RoHS compliance. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical differentiation. The SJPZ-N33VL currently maintains higher inventory levels (9400 pcs vs. 773 pcs), making it suitable for high-volume production scenarios where supply continuity is a priority. Both parts meet automotive-grade specifications and are appropriate for applications requiring transient voltage suppression in the 31V breakdown voltage range with 500W peak pulse power handling.

Frequently Asked Questions (FAQ)

Q: Can SJPZ-N33VL be used as a direct replacement for SJPZ-N33VR in existing designs?

A: Yes. Both parts share identical electrical specifications (31V breakdown voltage, 500W peak pulse power), mechanical packaging (2-SMD J-Lead, SJP package), operating temperature range (-55°C to 150°C), and automotive qualification (AEC-Q101). No circuit redesign or PCB modification is required.

Q: Are there any differences in the SJP package between these two part numbers?

A: No. Both parts use the identical 2-SMD, J-Lead package configuration with SJP supplier device package designation. PCB footprints and assembly processes remain unchanged.

Q: Do both parts meet the same automotive qualification standards?

A: Yes. Both SJPZ-N33VR and SJPZ-N33VL carry AEC-Q101 qualification and automotive-grade classification, meeting identical reliability and environmental stress screening requirements.

Q: What is the difference between the VR and VL suffixes?

A: The VR and VL suffixes represent different tape and reel packaging configurations from Sanken Electric USA Inc. Both maintain identical component specifications and are functionally equivalent for circuit applications.

Q: Are both parts RoHS compliant?

A: Yes. Both SJPZ-N33VR and SJPZ-N33VL are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity level, suitable for standard PCB assembly and storage conditions.
