BZT52B75S RRG Equivalent & Substitute Parts

Part Overview

The BZT52B75S RRG is a Zener diode manufactured by Taiwan Semiconductor Corporation, rated for 75 V nominal Zener voltage with 200 mW maximum power dissipation. This surface mount component operates across the temperature range of -65°C to 150°C and is housed in an SOD-323F package. The device maintains an active product status and carries full RoHS3 compliance with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity. Alternative sources provide identical or compatible electrical and mechanical specifications suitable for direct circuit board replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BZT52B75S RRG is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Zener voltage rating: 75 V nominal
• Maximum power dissipation: 200 mW
• Package type: SOD-323F (SC-90)
• Mounting configuration: Surface Mount
• Operating temperature range: -65°C to 150°C minimum
• Reverse leakage current: 45 nA @ 52.5 V
• Forward voltage: 1 V maximum @ 10 mA

Tolerance Consideration: Zener voltage tolerance varies between substitute options. The main part specifies ±2% tolerance, while one substitute permits ±5% tolerance. Selection depends on circuit requirements for voltage regulation precision.

Impedance Variation: Maximum impedance ranges from 240 to 255 Ohms across the part family. This parameter variation remains within acceptable limits for equivalent circuit performance in standard Zener regulation applications.

All substitute parts maintain identical compliance certifications (RoHS3, REACH Unaffected, EAR99 classification) and moisture sensitivity ratings.

Parameter Comparison

Engineering Selection Recommendations

MM3Z75VB (onsemi) - Direct Equivalent: The MM3Z75VB maintains identical electrical specifications to the BZT52B75S RRG, including ±2% Zener voltage tolerance, 200 mW power rating, and 45 nA reverse leakage current. This part carries ROHS3 compliance and unlimited moisture sensitivity rating. The MM3Z75VB is suitable for direct substitution in applications requiring precision voltage regulation with tight tolerance specifications.

MM3Z75VC (Fairchild Semiconductor) - Compatible Substitute: The MM3Z75VC provides functional equivalence with relaxed Zener voltage tolerance of ±5% compared to the main part's ±2% specification. All other electrical parameters remain aligned: 75 V nominal rating, 200 mW power dissipation, and identical reverse leakage characteristics. This part is applicable in applications where voltage regulation tolerance of ±5% satisfies circuit requirements. Compliance certifications for this part are not specified in available documentation.

Both substitute parts are housed in identical SOD-323F packages and support surface mount assembly processes without modification to board layouts or pick-and-place programming.

Frequently Asked Questions (FAQ)

Q: Can MM3Z75VB replace BZT52B75S RRG without circuit modification?

A: Yes. The MM3Z75VB is a direct electrical equivalent with matching Zener voltage (75 V), power rating (200 mW), tolerance (±2%), and package configuration (SOD-323F). No circuit modifications are required for substitution.

Q: What is the primary difference between MM3Z75VB and MM3Z75VC?

A: The MM3Z75VC specifies ±5% Zener voltage tolerance, compared to ±2% for both the BZT52B75S RRG and MM3Z75VB. All other electrical parameters are identical. Selection between these parts depends on circuit tolerance requirements for Zener voltage regulation.

Q: Are all substitute parts available in the same package?

A: Yes. All parts listed—BZT52B75S RRG, MM3Z75VB, and MM3Z75VC—use the SOD-323F package (SC-90 case). Board layouts and assembly processes remain unchanged during substitution.

Q: Do substitute parts meet the same compliance standards?

A: The MM3Z75VB carries ROHS3 compliance and unlimited moisture sensitivity rating, matching the main part. The MM3Z75VC compliance certifications are not specified in available documentation. Verify compliance requirements with your procurement or quality assurance department before selecting this part.

Q: What is the impedance difference between the main part and substitutes?

A: The BZT52B75S RRG specifies 255 Ohms maximum impedance, while both MM3Z75VB and MM3Z75VC specify 240 Ohms maximum. This 15 Ohm variation remains within acceptable limits for standard Zener regulation circuits and does not affect functional equivalence.

Q: Can these parts be used interchangeably in high-precision voltage reference applications?

A: The MM3Z75VB maintains ±2% tolerance matching the main part and is suitable for precision applications. The MM3Z75VC with ±5% tolerance is applicable only in applications where this relaxed tolerance specification is acceptable.

Q: What are the reverse leakage characteristics across all parts?

A: All three parts specify identical reverse leakage current of 45 nA measured at 52.5 V reverse bias. This parameter is consistent across the entire part family.
