SMDA05C-5E3/TR13 Equivalent & Substitute Parts

Part Overview

The SMDA05C-5E3/TR13 is a bidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology. This surface-mount device is designed for general-purpose transient voltage protection in 8-SOIC packaging. The part operates across a temperature range of -55°C to 150°C and features five bidirectional channels with a 5V reverse standoff voltage and 11V maximum clamping voltage at peak pulse current.

The SMDA05C-5E3/TR13 maintains Active product status and is RoHS3 compliant with unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and design continuity when the primary part becomes unavailable or when alternative electrical characteristics better suit specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMDA05C-5E3/TR13 are identified based on strict electrical and mechanical compatibility criteria. The following parameters define acceptable substitution:

Primary Substitution Criteria:

• Bidirectional channel count: 5 channels (required match)
• Reverse standoff voltage: 5V (required match)
• Breakdown voltage minimum: 6V (required match)
• Package type: 8-SOIC surface mount (required match)
• Mounting configuration: Surface mount (required match)

Secondary Compatibility Parameters:

• Clamping voltage at peak pulse current (Ipp)
• Peak pulse current rating (8/20µs)
• Peak pulse power rating
• Operating temperature range
• Capacitance characteristics
• Compliance certifications (RoHS, REACH, ECCN)

The SMDA05C-5.TBT from Semtech Corporation qualifies as a substitute part. Both devices share identical reverse standoff voltage (5V), breakdown voltage minimum (6V), bidirectional channel configuration (5), and 8-SOIC package specifications. Electrical performance differences exist in clamping voltage (9.8V versus 11V) and peak pulse current capability (17A versus 5A), which represent measurable variations in transient suppression characteristics but do not preclude substitution in applications where the substitute's specifications remain within system tolerance limits.

Engineering Selection Recommendations

SMDA05C-5E3/TR13 (Microchip Technology)

Select this part when the application requires the specified clamping voltage of 11V at peak pulse current and operates within the extended temperature range of -55°C to 150°C. This device is RoHS3 compliant and maintains Active product status with established supply availability. The lower capacitance value (200pF @ 1MHz) is suitable for high-frequency signal integrity applications where minimal parasitic capacitance is required.

SMDA05C-5.TBT (Semtech Corporation)

Select this part when the application benefits from lower clamping voltage (9.8V) and higher peak pulse current capability (17A). This substitute is RoHS compliant and maintains Active product status. The operating temperature range extends to 125°C, which is suitable for most industrial and commercial applications. Higher capacitance (350pF @ 1MHz) may be acceptable in applications where transient suppression takes priority over high-frequency signal preservation.

Both parts share identical package geometry, channel configuration, and reverse standoff voltage specifications, enabling direct PCB layout compatibility without redesign. Selection between these parts depends on specific clamping voltage requirements, peak pulse current demands, and operating temperature constraints of the target application.

Frequently Asked Questions (FAQ)

Q: Can the SMDA05C-5.TBT directly replace the SMDA05C-5E3/TR13 on the same PCB?

A: Yes. Both devices use identical 8-SOIC package geometry (0.154" width, 3.90mm) and surface-mount configuration. No PCB layout modifications are required for physical substitution.

Q: What is the difference in clamping voltage between these two parts?

A: The SMDA05C-5E3/TR13 clamps at a maximum of 11V at peak pulse current, while the SMDA05C-5.TBT clamps at 9.8V. The lower clamping voltage of the Semtech part provides tighter voltage regulation during transient events.

Q: Why does the SMDA05C-5.TBT have a higher peak pulse current rating?

A: The SMDA05C-5.TBT is rated for 17A peak pulse current (8/20µs) compared to 5A for the Microchip part. This indicates the Semtech device can handle higher transient current magnitudes while maintaining the same 300W peak pulse power rating.

Q: Are there temperature range differences between these parts?

A: Yes. The SMDA05C-5E3/TR13 operates from -55°C to 150°C, while the SMDA05C-5.TBT operates from -55°C to 125°C. The Microchip part supports higher maximum junction temperatures.

Q: Do both parts have the same reverse standoff voltage?

A: Yes. Both devices maintain a 5V reverse standoff voltage and 6V minimum breakdown voltage, ensuring identical voltage protection thresholds.

Q: What is the significance of the capacitance difference?

A: The SMDA05C-5E3/TR13 has 200pF capacitance at 1MHz, while the SMDA05C-5.TBT has 350pF. Lower capacitance is preferable in high-speed signal applications to minimize signal distortion. Higher capacitance may provide improved transient suppression in lower-frequency applications.

Q: Are both parts RoHS compliant?

A: Yes. The SMDA05C-5E3/TR13 is RoHS3 compliant, and the SMDA05C-5.TBT is RoHS compliant. Both meet environmental regulatory requirements.

Q: What does the 8-SO package designation mean?

A: 8-SO refers to an 8-pin Small Outline integrated circuit package. Both parts use this standard surface-mount package type with 0.154 inches (3.90mm) width.

Q: Can I use the SMDA05C-5.TBT in an application designed for the SMDA05C-5E3/TR13?

A: Substitution is possible if the application tolerates the lower clamping voltage (9.8V versus 11V), higher peak pulse current capability (17A versus 5A), and reduced maximum operating temperature (125°C versus 150°C). Verify that these electrical differences remain within system design specifications before implementation.
