SMP36-M3/85A Equivalent & Substitute Parts

Part Overview

The SMP36-M3/85A is a unidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, part of the TransZorb® and eSMP® series. This component is designed for general-purpose transient voltage suppression applications requiring a 36V reverse standoff voltage with 64.3V maximum clamping voltage. The part is Active status and widely used in circuit protection applications where transient overvoltage events must be rapidly suppressed. Identifying equivalent and substitute parts is necessary when the primary part number is unavailable, when inventory constraints exist, or when packaging requirements differ while maintaining identical electrical performance.

Key Parameters

Substitute Part Grouping Explanation

The SMP36-M3/85A has one direct equivalent substitute: SMP36A-M3/84A. This substitution is valid based on the following critical parameters that determine functional interchangeability:

• Voltage - Reverse Standoff (Typ): 36V (identical)
• Voltage - Breakdown (Min): 40V (identical)
• Voltage - Clamping (Max) @ Ipp: 64.3V (identical)
• Current - Peak Pulse (10/1000µs): 6.2A (identical)
• Power - Peak Pulse: 400W (identical)
• Operating Temperature Range: -55°C ~ 150°C (TJ) (identical)
• Package / Case: DO-220AA (identical)
• Mounting Type: Surface Mount (identical)
• Series: TransZorb®, eSMP® (identical)
• Type: Zener, Unidirectional (identical)

The primary difference between these parts is the packaging format: SMP36-M3/85A is supplied in standard packaging, while SMP36A-M3/84A is supplied in Tape & Reel (TR) format. Both parts share the same base product number (SMP36) and maintain identical electrical and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

Both SMP36-M3/85A and SMP36A-M3/84A are Active status components from Vishay General Semiconductor - Diodes Division and are ROHS3 Compliant with REACH Unaffected status. Selection between these parts should be based on packaging and supply chain requirements:

• SMP36-M3/85A: Select when standard packaging is required or when inventory availability is the primary constraint (741 Pcs in stock).
• SMP36A-M3/84A: Select when Tape & Reel (TR) packaging is required for automated assembly processes or high-volume production (10,100 Pcs in stock).

Both parts are electrically and thermally identical and will perform identically in circuit protection applications requiring 36V reverse standoff voltage suppression with 64.3V maximum clamping voltage.

Frequently Asked Questions (FAQ)

Q: Can SMP36A-M3/84A be used as a direct replacement for SMP36-M3/85A?

A: Yes. Both parts are electrically and thermally identical with matching voltage ratings (36V reverse standoff, 64.3V clamping), current ratings (6.2A peak pulse), power dissipation (400W), operating temperature range (-55°C to 150°C), and package type (DO-220AA surface mount). The only difference is packaging format (Tape & Reel vs. standard).

Q: What is the difference between SMP36-M3/85A and SMP36A-M3/84A?

A: The primary difference is packaging format. SMP36-M3/85A uses standard packaging, while SMP36A-M3/84A uses Tape & Reel (TR) format. All electrical specifications, thermal characteristics, and compliance certifications are identical.

Q: Are these parts suitable for automated assembly?

A: SMP36A-M3/84A in Tape & Reel format is optimized for automated assembly processes. SMP36-M3/85A in standard packaging may require manual handling or conversion to tape format depending on assembly equipment.

Q: Do both parts meet the same compliance standards?

A: Yes. Both SMP36-M3/85A and SMP36A-M3/84A are ROHS3 Compliant, REACH Unaffected, and classified as EAR99 with HTSUS code 8541.10.0080. Both have Moisture Sensitivity Level 1 (Unlimited).

Q: What is the operating temperature range for these TVS diodes?

A: Both parts operate across -55°C to 150°C junction temperature (TJ), suitable for industrial and automotive applications requiring wide temperature range protection.
