SMDA05-6/TR13 Equivalent & Substitute Parts

Part Overview

The SMDA05-6/TR13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection applications. This 6-channel TVS array operates with a 5V reverse standoff voltage and provides 11V clamping at peak pulse current, housed in an 8-SOIC surface mount package. The device is currently active in production and available in tape and reel packaging.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits alternative sourcing while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMDA05-6/TR13 are qualified based on the following critical parameters that determine functional interchangeability:

Primary Compatibility Criteria:

• Voltage - Reverse Standoff: 5V (nominal)
• Voltage - Breakdown (Min): 6V or greater
• Voltage - Clamping (Max) @ Ipp: 11V or less
• Unidirectional Channels: 6
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

Secondary Considerations:

• Current - Peak Pulse rating (8/20µs): Equal to or greater than 5A
• Power - Peak Pulse: Equal to or greater than 200W
• Operating Temperature Range: Minimum -55°C to maximum 125°C or higher
• RoHS and REACH compliance status

Parts meeting these criteria are classified as direct substitutes. Deviations in non-critical parameters (such as capacitance or exact clamping voltage within tolerance) do not preclude substitution when primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

SMDA05-6.TBT (Semtech Corporation):

This part is a direct substitute for the SMDA05-6/TR13. Both devices share identical voltage ratings (5V reverse standoff, 6V breakdown minimum, 11V clamping maximum), six unidirectional channels, and 8-SOIC package geometry. The SMDA05-6.TBT provides higher peak pulse current capability (17A versus 5A), which represents an enhancement in transient handling capacity without compromising compatibility. Both parts maintain 300W peak pulse power rating and identical ECCN/HTSUS classifications. The SMDA05-6.TBT is ROHS3 compliant, whereas the original part is non-compliant. Operating temperature range differs slightly (-55°C to 125°C for SMDA05-6.TBT versus -55°C to 150°C for SMDA05-6/TR13); this represents a minor reduction in maximum junction temperature. Inventory availability for SMDA05-6.TBT is 1407 units.

ESDA6V1U1RL (STMicroelectronics):

This part qualifies as a substitute based on matching voltage standoff (5V), breakdown minimum (6.1V, within acceptable tolerance), six unidirectional channels, and identical 8-SOIC package footprint. However, critical electrical parameters including peak pulse current, clamping voltage at Ipp, and operating temperature range are not specified in available documentation. The ESDA6V1U1RL is rated for 200W peak pulse power, which is lower than the 300W specification of the main part. ROHS3 compliance and REACH unaffected status are confirmed. This part is available in cut tape and Digi-Reel® packaging rather than tape and reel. Inventory availability is 20789 units. Substitution with ESDA6V1U1RL requires verification that unspecified electrical parameters meet application requirements.

Frequently Asked Questions (FAQ)

Q: Can SMDA05-6.TBT be used as a direct replacement for SMDA05-6/TR13 in all applications?

A: Yes, SMDA05-6.TBT is a direct substitute. Both parts share the same voltage ratings (5V standoff, 6V breakdown, 11V clamping), channel configuration (6 unidirectional), and package footprint (8-SOIC). The SMDA05-6.TBT provides higher peak pulse current (17A versus 5A), which is compatible with applications designed for the lower 5A rating. The maximum operating temperature differs by 25°C (125°C versus 150°C); verify this does not exceed your application's junction temperature requirements.

Q: What are the key differences between SMDA05-6/TR13 and ESDA6V1U1RL?

A: Both parts share 5V reverse standoff voltage, 6V minimum breakdown voltage, six unidirectional channels, and 8-SOIC package geometry. The ESDA6V1U1RL has a breakdown minimum of 6.1V (slightly higher), and peak pulse power is rated at 200W versus 300W for the SMDA05-6/TR13. Critical parameters including peak pulse current, clamping voltage at Ipp, and operating temperature range are not provided for the ESDA6V1U1RL. Packaging differs: ESDA6V1U1RL is supplied in cut tape and Digi-Reel® format, while SMDA05-6/TR13 is supplied in tape and reel.

Q: Are there RoHS compliance differences between these parts?

A: Yes. The SMDA05-6/TR13 is RoHS non-compliant. Both SMDA05-6.TBT and ESDA6V1U1RL are ROHS3 compliant. If your application or supply chain requires RoHS compliance, either substitute part is acceptable. All three parts are REACH unaffected.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (tape and reel versus cut tape and Digi-Reel®) affects handling, storage, and assembly logistics but does not alter electrical characteristics. Selection between packaging formats depends on your manufacturing process and inventory management requirements.

Q: What is the significance of the 550pF versus 400pF capacitance difference?

A: The SMDA05-6/TR13 has 550pF capacitance at 1MHz, while SMDA05-6.TBT has 400pF. This difference may affect high-frequency circuit behavior. In applications where capacitance is a critical parameter (such as high-speed signal line protection), verify that the lower capacitance of SMDA05-6.TBT does not introduce unacceptable signal distortion or impedance mismatch.

Q: Can I substitute ESDA6V1U1RL if peak pulse current and clamping voltage specifications are not provided?

A: Substitution with ESDA6V1U1RL requires that you obtain complete electrical specifications from STMicroelectronics and verify that unspecified parameters (peak pulse current, clamping voltage at Ipp, operating temperature range) meet your application requirements. The 200W peak pulse power rating is lower than the 300W specification of the main part; confirm this does not limit transient protection capability in your circuit.

Q: Are all three parts suitable for general-purpose overvoltage protection?

A: Yes. All three parts are classified for general-purpose applications and are designed for transient voltage suppression in surface mount configurations. Application suitability depends on matching the specific voltage ratings, current handling, and thermal characteristics to your circuit requirements.
