MPLAD30KP85A Equivalent & Substitute Parts

Part Overview

The MPLAD30KP85A is a unidirectional Zener-type Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology. This surface mount component is designed for general-purpose transient voltage suppression applications, featuring an 85V reverse standoff voltage and 137V maximum clamping voltage. The device is currently in active production status. Identification of equivalent and substitute parts is necessary to ensure design flexibility, manage supply chain continuity, and accommodate varying compliance requirements across different manufacturing batches and procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of TVS diodes is determined by electrical and mechanical parameter equivalence. The MPLAD30KP85A and its substitute must satisfy the following criteria:

Electrical Parameters (Critical for Substitution):

• Voltage - Reverse Standoff (Typ): 85V
• Voltage - Breakdown (Min): 94.4V
• Voltage - Clamping (Max) @ Ipp: 137V
• Current - Peak Pulse (10/1000µs): 216A
• Power - Peak Pulse: 30000W

Mechanical Parameters (Critical for Substitution):

• Unidirectional Channels: 1
• Type: Zener
• Mounting Type: Surface Mount
• Package / Case: Nonstandard SMD (PLAD)
• Operating Temperature Range: -55°C to 150°C

Environmental & Compliance Parameters:

• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected
• ECCN: EAR99

Parts meeting all electrical, mechanical, and environmental parameters are classified as direct substitutes. Variations in RoHS compliance status do not affect electrical or mechanical substitutability but may impact procurement and regulatory requirements.

Engineering Selection Recommendations

MPLAD30KP85AE3 as Direct Substitute:

The MPLAD30KP85AE3 is a direct electrical and mechanical substitute for the MPLAD30KP85A. All critical electrical parameters—reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, and peak pulse power—are identical. The package, mounting type, and operating temperature range are equivalent. Both devices are manufactured by Microchip Technology and carry active product status.

The primary distinction between these parts is RoHS compliance status. The MPLAD30KP85A is RoHS non-compliant, while the MPLAD30KP85AE3 is ROHS3 compliant. This difference does not affect electrical performance or mechanical compatibility. Selection between these parts should be based on regulatory and procurement requirements specific to the end application and target market.

The MPLAD30KP85AE3 offers higher inventory availability (1211 pieces versus 931 pieces), which may provide supply chain advantages for high-volume production scenarios.

Frequently Asked Questions (FAQ)

Q: Can MPLAD30KP85AE3 be used as a direct replacement for MPLAD30KP85A in existing designs?

A: Yes. The MPLAD30KP85AE3 is electrically and mechanically equivalent to the MPLAD30KP85A. All voltage ratings, current ratings, power dissipation, package type, and operating temperature specifications are identical. No circuit modifications or PCB layout changes are required.

Q: What is the difference between MPLAD30KP85A and MPLAD30KP85AE3?

A: The primary difference is RoHS compliance status. MPLAD30KP85A is RoHS non-compliant, while MPLAD30KP85AE3 is ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Does RoHS compliance affect the performance of the TVS diode?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical transient voltage suppression characteristics.

Q: Are both parts available in the same PLAD package?

A: Yes. Both MPLAD30KP85A and MPLAD30KP85AE3 use the PLAD nonstandard SMD package. PCB footprints and assembly processes are identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, use MPLAD30KP85AE3. For applications without RoHS requirements, either part is suitable. The MPLAD30KP85AE3 offers higher inventory availability.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are electrically and mechanically equivalent, they can be used interchangeably within the same design and production run. However, compliance documentation should reflect the specific part numbers used.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 150°C (junction temperature). This range applies to all electrical specifications and performance guarantees.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use the identical PLAD nonstandard SMD package. Footprints, land patterns, and assembly requirements are the same.
