Key Parameters

Substitute Part Grouping Explanation

Substitution of the SMCJ36A-TP is determined by strict electrical and mechanical compatibility criteria. All substitute parts must maintain the following core parameters:

• Voltage - Reverse Standoff (Typ): 36V
• Voltage - Breakdown (Min): 40V
• Voltage - Clamping (Max) @ Ipp: 58.1V
• Unidirectional Channels: 1
• Type: Zener
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Substitute parts are grouped into two categories:

Direct Equivalents (Identical Electrical & Package Specifications): Parts with matching voltage ratings, clamping characteristics, and DO-214AB SMC package configuration.

Similar Substitutes (Electrical Match with Package or Current Variations): Parts meeting voltage and clamping specifications but with different package types (SMA vs. SMC), peak pulse current ratings, or power dissipation capabilities. These are suitable where mechanical constraints or thermal requirements differ from the original specification.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Preferred for Pin-Compatible Replacement):

SMCJ36A-13-F (Diodes Incorporated) provides the closest electrical and mechanical match to SMCJ36A-TP. Both components feature identical 36V standoff voltage, 58.1V clamping voltage, DO-214AB SMC package, and 1500W peak pulse power rating. Operating temperature range differs slightly (-55 to 150°C vs. -55 to 175°C), which is acceptable for most general-purpose applications. ROHS3 compliance and MSL 1 rating are maintained.

Higher Current Capability Substitutes:

5.0SMDJ36A (Taiwan Semiconductor Corporation) and 5.0SMDJ36A-T7 (Littelfuse Inc.) maintain identical voltage specifications and DO-214AB SMC packaging while providing 86.1A peak pulse current and 5000W power dissipation. These are suitable for applications requiring enhanced transient suppression capability. Both are ROHS3 compliant.

SMDJ36A-T7 (Littelfuse Inc.) and SMLJ36A (Bourns Inc.) offer intermediate current ratings of 51.6A with 3000W power dissipation, maintaining DO-214AB SMC package compatibility and ROHS3 compliance.

Package Variant:

SMCJ36A (EVVO Semi) matches electrical specifications but uses DO-214AC SMA package instead of SMC. This variant is suitable only where mechanical board layout permits SMA footprint substitution. Power dissipation is reduced to 600W, limiting application scope.

Automotive-Grade Option:

SZ1SMC36AT3G (Littelfuse Inc.) is AEC-Q101 qualified and suitable for automotive applications. It maintains 36V standoff, 58.1V clamping, and DO-214AB SMC package with 35.8A peak pulse current and 1500W power rating.

Frequently Asked Questions (FAQ)

Q: Can SMCJ36A-TP be directly replaced with SMCJ36A-13-F?

A: Yes. Both components share identical voltage ratings (36V standoff, 58.1V clamping), peak pulse current (25.8-25.9A), power dissipation (1500W), and DO-214AB SMC package. Operating temperature range differs by 25°C at the upper limit, which does not affect general-purpose applications.

Q: What is the difference between SMC and SMA packages?

A: SMC (DO-214AB) and SMA (DO-214AC) are distinct surface-mount packages with different footprint geometries. SMCJ36A (EVVO Semi) uses SMA packaging and cannot be directly substituted without PCB redesign. Verify footprint compatibility before selection.

Q: When should higher current-rated parts like 5.0SMDJ36A be used?

A: Higher current-rated substitutes (86.1A, 5000W) are selected when transient pulse magnitudes exceed the original specification or when thermal margin is required. Electrical compatibility (voltage ratings) remains identical; selection is driven by application transient severity.

Q: Is SZ1SMC36AT3G suitable for non-automotive applications?

A: Yes. SZ1SMC36AT3G meets all electrical and mechanical requirements for general-purpose use. AEC-Q101 qualification indicates enhanced reliability screening and is not restrictive for non-automotive designs.

Q: What does ROHS3 compliance mean for substitution?

A: ROHS3 compliance indicates the component meets Restriction of Hazardous Substances Directive requirements. All listed substitutes maintain ROHS3 compliance, ensuring regulatory consistency across supply chain alternatives.

Q: Can SMDJ36A be used as a substitute?

A: SMDJ36A (EVVO Semi) maintains voltage specifications and DO-214AB package but lacks complete electrical parameter documentation in the provided data. Verify detailed specifications with the manufacturer before selection.
