SMDA05-6E3/TR13 Transient Voltage Suppressor Diode

Part Overview

The SMDA05-6E3/TR13 is an active-status Microchip Technology TVS diode designed for general-purpose transient voltage suppression in 8-SOIC surface mount packages. This unidirectional six-channel TVS array operates with a 5V reverse standoff voltage and 11V maximum clamping voltage. Alternative models become necessary due to supply constraints, packaging variations, or application-specific current rating requirements while maintaining equivalent electrical performance within specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of TVS diode SMDA05-6E3/TR13 is based on electrical parameter equivalence within the following allowable tolerances and constraints:

Critical Matching Parameters:

• Voltage - Reverse Standoff: 5V (typ)
• Voltage - Breakdown (Min): 6V
• Voltage - Clamping (Max) @ Ipp: 11V
• Unidirectional Channels: 6
• Package: 8-SOIC surface mount
• RoHS3 Compliance

Allowable Variations:

• Current - Peak Pulse: Parts rated 5A or higher satisfy the requirement
• Power - Peak Pulse: 200W minimum acceptable
• Capacitance @ 1MHz: Variations up to ±200pF acceptable
• Packaging format: Both Tape & Reel (TR) and Cut Tape (CT) with Digi-Reel® are acceptable

Parts meeting these criteria are classified as direct equivalents or functionally equivalent substitutes.

Parameter Comparison

Engineering Selection Recommendations

SMDA05-6E3/TR7 (Microchip Technology): Direct equivalent offering identical electrical specifications and temperature range. Higher inventory availability (10,635 pcs) provides supply chain advantage. Identical packaging format and RoHS3 compliance ensure seamless integration. Recommended as primary substitute for SMDA05-6E3/TR13.

ESDA6V1U1RL (STMicroelectronics): Functionally equivalent for voltage parameters (5V reverse standoff, 6.1V breakdown). Meets alternative packaging requirement via Cut Tape format with Digi-Reel® availability. Lower peak pulse power (200W vs. 300W) suitable for applications not requiring the maximum power specification. RoHS3 compliance confirmed. Highest inventory (20,789 pcs). Operating temperature range not specified; application verification required for temperature-sensitive deployments.

SMDA05-6.TBT (Semtech Corporation): Enhanced current rating (17A vs. 5A) provides additional transient suppression margin in pulse applications. Reduced operating temperature upper limit (125°C vs. 150°C) restricts suitability to applications below this threshold. Capacitance differential (400pF vs. 550pF) represents minor variance. RoHS3 compliant and active product status confirmed. Selection appropriate where higher current capability is required and temperature constraint (≤125°C) is acceptable.

Frequently Asked Questions (FAQ)

Q: Are SMDA05-6E3/TR13 and SMDA05-6E3/TR7 electrically identical?

A: Yes. Both parts share identical voltage ratings (5V reverse standoff, 6V breakdown, 11V clamping), current specifications (5A peak pulse), power dissipation (300W), capacitance (550pF @ 1MHz), and operating temperature range (-55°C ~ 150°C). Difference lies in tape reel supplier designation (TR13 vs. TR7). Functionality is equivalent.

Q: Can ESDA6V1U1RL substitute SMDA05-6E3/TR13 in all applications?

A: ESDA6V1U1RL matches critical voltage parameters and unidirectional channel count. Peak pulse power specification is lower (200W vs. 300W). Use in applications requiring full 300W peak pulse dissipation requires verification. Operating temperature range is not specified in the provided data. Applications requiring confirmed operation at maximum temperature (≥125°C) require clarification of ESDA6V1U1RL temperature limits through manufacturer documentation.

Q: When is SMDA05-6.TBT the better choice?

A: SMDA05-6.TBT is superior when applications require higher peak pulse current handling (17A vs. 5A per channel). Use when transient events exceed 5A suppression capacity. Operating temperature constraint (125°C maximum junction temperature) must be verified as acceptable for the application environment. All other electrical and package parameters support direct substitution.

Q: What is the significance of the 8-SOIC package specification?

A: All four parts utilize 8-SOIC (0.154" width, 3.90mm) surface mount packaging, ensuring physical compatibility with existing PCB footprints and assembly processes. No mechanical redesign required for substitution. Packaging format (Tape & Reel vs. Cut Tape with Digi-Reel) affects handling and supply chain logistics but does not impact electrical or mechanical performance.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. SMDA05-6E3/TR7, ESDA6V1U1RL, and SMDA05-6.TBT are all RoHS3 compliant, meeting environmental and regulatory requirements equivalent to the primary part.
