Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BZT52C30T-TP are identified based on the following critical parameters:

Primary Matching Criteria:

• Zener voltage: 30 V nominal
• Operating temperature range: -65°C to 150°C
• Surface mount technology
• RoHS3 compliance

Substitution Logic: Substitute parts are grouped into two categories based on package compatibility and power rating:

Category 1: Same Package (SOD-523) with Higher Power Ratings Parts maintaining the SOD-523 package allow direct PCB layout compatibility. Higher power ratings (300 mW to 500 mW) provide design margin while maintaining the same footprint. These substitutes are suitable when the application can tolerate increased power dissipation capability.

Category 2: Alternative Packages (SOD-123F, SOD-323F) with Higher Power Ratings Parts using different surface mount packages (SOD-123F, SOD-323F) require PCB layout modification but offer higher power ratings (375 mW to 550 mW). These are suitable for applications where package size constraints are not critical and higher power handling is beneficial.

Tolerance Consideration: Substitute parts with tighter tolerance specifications (±2%, ±5%) are acceptable replacements for the ±7% tolerance requirement of the main part.

Parameter Comparison

Engineering Selection Recommendations

For Direct PCB Layout Compatibility (SOD-523 Package):

BZX585-C30,115 and BZX585-B30,115 are suitable substitutes when PCB layout cannot be modified. Both maintain the SOD-523 package footprint identical to BZT52C30T-TP. BZX585-C30,115 matches the ±5% tolerance specification and provides 300 mW power rating. BZX585-B30,115 offers tighter ±2% tolerance with the same 300 mW rating. Both are RoHS3 compliant and rated for -65°C to 150°C operation.

SZMM5Z30VT1G from onsemi maintains SOD-523 package compatibility with 500 mW power rating and ±6.7% tolerance. This part is RoHS3 compliant and AEC-Q101 qualified for automotive applications.

For Applications Requiring Higher Power Dissipation:

BZX84J-C30,115 and BZX84J-B30,115 provide 550 mW power rating in SOD-323F package. BZX84J-C30,115 maintains ±5% tolerance matching the substitute tolerance range. BZX84J-B30,115 offers ±2% tolerance. Both require PCB layout modification due to different package footprint. Both are RoHS3 compliant and AEC-Q101 qualified.

BZT52H-C30,115 from NXP provides 375 mW in SOD-123F package with ±5% tolerance. This part requires PCB layout modification and is AEC-Q101 qualified.

Compliance Status:

All identified substitute parts maintain RoHS3 compliance and -65°C to 150°C operating temperature range. Automotive-grade substitutes (BZX585 series, BZX84J series, SZMM5Z30VT1G) carry AEC-Q100 or AEC-Q101 qualification.

Frequently Asked Questions (FAQ)

Q: Can BZX585-C30,115 replace BZT52C30T-TP directly on the PCB?

A: Yes. BZX585-C30,115 uses the same SOD-523 package as BZT52C30T-TP, allowing direct PCB placement without layout modification. Both parts maintain 30 V nominal Zener voltage, -65°C to 150°C operating temperature, and RoHS3 compliance.

Q: What is the difference between BZX585-B30,115 and BZX585-C30,115?

A: Both parts use SOD-523 package and provide 300 mW power rating at 30 V. The primary difference is tolerance specification: BZX585-B30,115 is ±2% while BZX585-C30,115 is ±5%. The ±2% tolerance of BZX585-B30,115 provides tighter voltage regulation.

Q: Can I use BZX84J-C30,115 as a substitute if my PCB layout cannot be modified?

A: No. BZX84J-C30,115 uses SOD-323F package, which has a different footprint than the SOD-523 package of BZT52C30T-TP. PCB layout modification is required for this substitution.

Q: Are all substitute parts RoHS3 compliant?

A: All identified substitute parts are RoHS3 compliant. BZT52H-C30,115 does not specify RoHS status in the provided data.

Q: What is the advantage of SZMM5Z30VT1G over BZX585-C30,115?

A: SZMM5Z30VT1G provides 500 mW power rating compared to 300 mW for BZX585-C30,115, while maintaining the same SOD-523 package. Both parts are RoHS3 compliant and operate across -65°C to 150°C. SZMM5Z30VT1G carries AEC-Q101 automotive qualification.

Q: Can I use a substitute part with higher power rating in a 100 mW application?

A: Yes. Substitute parts with higher power ratings (300 mW, 375 mW, 500 mW, 550 mW) are acceptable for applications designed for 100 mW. The higher power rating provides design margin and does not degrade performance in lower power applications.

Q: What tolerance should I select for critical voltage regulation applications?

A: For applications requiring tighter voltage regulation, select substitute parts with ±2% tolerance: BZX585-B30,115 or BZX84J-B30,115. These provide superior voltage stability compared to the ±7% tolerance of BZT52C30T-TP.

Q: Are automotive-qualified substitutes available?

A: Yes. BZX585-B30,115, BZX585-C30,115, BZX84J-B30,115, BZX84J-C30,115, and SZMM5Z30VT1G all carry automotive qualification (AEC-Q100 or AEC-Q101).
