SMF36A-TP Equivalent & Substitute Parts

Part Overview

The SMF36A-TP is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient protection applications. This surface-mount component operates with a 36V reverse standoff voltage and provides 58.1V maximum clamping voltage at peak pulse current. The part is actively produced and RoHS3 compliant, making it suitable for modern electronic designs requiring transient voltage suppression in the 36V protection class.

Equivalent and substitute parts are identified when they maintain identical or compatible electrical characteristics within the specified parameter tolerances and share compatible mechanical packaging for direct circuit board replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMF36A-TP are classified based on strict electrical and mechanical compatibility criteria:

Direct Substitutes maintain all critical electrical parameters within specification:

• Reverse standoff voltage: 36V
• Breakdown voltage minimum: 40V
• Clamping voltage maximum: 58.1V
• Peak pulse current: 3.4A or higher
• Package: SOD-123F surface mount
• RoHS3 compliance

Parts are grouped as direct substitutes when they satisfy these parameters simultaneously, ensuring functional equivalence in circuit protection applications without design modification.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and RoHS3 compliance, confirming ongoing manufacturer support and regulatory alignment for current applications.

SMF36A (MDD) provides direct electrical substitution with peak pulse current of 3.44A, exceeding the 3.4A specification of the primary part. This part carries the highest inventory availability (20,865 units) and maintains identical voltage protection parameters.

SMF36A_R1_00001 (Panjit International Inc.) matches the original part's 3.4A peak pulse current specification exactly and maintains all voltage parameters. This part is REACH Unaffected and carries 5,350 units in inventory.

Both substitute parts are mechanically compatible in SOD-123F surface-mount packaging and support equivalent circuit board assembly processes. Selection between substitutes depends on supply chain availability, lead time requirements, and manufacturer preference within the design organization.

Frequently Asked Questions (FAQ)

Q: Can SMF36A (MDD) replace SMF36A-TP in all applications?

A: Yes. The SMF36A maintains identical reverse standoff voltage (36V), breakdown voltage (40V minimum), and clamping voltage (58.1V maximum). The higher peak pulse current rating (3.44A versus 3.4A) provides additional margin without affecting circuit protection performance. Both parts use SOD-123F surface-mount packaging.

Q: What is the difference between SMF36A and SMF36A_R1_00001?

A: Both parts maintain identical electrical specifications for voltage protection (36V standoff, 40V breakdown, 58.1V clamping) and peak pulse current (3.4A). The primary differences are manufacturer (MDD versus Panjit International Inc.) and inventory levels. Both are RoHS3 compliant and use compatible SOD-123F packaging.

Q: Are there operating temperature differences between these parts?

A: The original SMF36A-TP operates from -65°C to 175°C. Both substitute parts operate from -55°C to 150°C. Applications requiring operation below -55°C or above 150°C must retain the original SMF36A-TP specification.

Q: Do all parts use the same package?

A: All three parts use SOD-123F surface-mount packaging, ensuring mechanical compatibility for direct board-level substitution without layout modification.

Q: Which part should be selected for new designs?

A: Selection is based on supply chain availability and manufacturer preference. All three parts meet the electrical and compliance requirements for 36V transient voltage suppression applications. Verify current inventory and lead times with your component supplier.
