SMCJ8.5AE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMCJ8.5AE3/TR13 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Microchip Technology, designed for general-purpose overvoltage protection in surface-mount applications. This component operates with a reverse standoff voltage of 8.5V and provides clamping at 13.6V maximum, with peak pulse current handling of 110.3A at 1500W peak pulse power. The device is packaged in DO-214AB (SMC) format and is RoHS3 compliant with unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified based on matching or compatible electrical characteristics within the 8.5V standoff voltage class, identical packaging format, and equivalent power dissipation capabilities. Substitutes maintain the same unidirectional channel configuration and surface-mount mounting type.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMCJ8.5AE3/TR13 are classified based on the following substitution criteria:

Direct Electrical Compatibility Parameters:

• Reverse standoff voltage: 8.5V (nominal)
• Unidirectional channel configuration: 1 channel
• Package format: DO-214AB / SMC surface mount
• Peak pulse power rating: 1500W or higher
• Operating temperature range: minimum -55°C to 150°C

Substitution Logic: Parts are grouped as direct or similar substitutes when they maintain the 8.5V standoff voltage class and DO-214AB packaging. Clamping voltage tolerance ranges from 13.6V to 14.5V, and peak pulse current ranges from 104.2A to 208.4A. All substitute parts listed are active products with RoHS3 compliance and unlimited moisture sensitivity rating.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Electrical and Mechanical Compatibility):

The SMCJ8.5A (EVVO Semi), SMCJ8.5A-13-F (Diodes Incorporated), and SMCJ8.5A-TP (Micro Commercial Co) are direct substitutes with matching 8.5V standoff voltage, 1500W peak pulse power, and DO-214AB packaging. These parts maintain functional equivalence with the SMCJ8.5AE3/TR13. All three are RoHS3 compliant and carry unlimited moisture sensitivity rating.

Similar Substitutes (Extended Capability):

The 1.5SMC10A (Taiwan Semiconductor Corporation) operates at 8.55V standoff voltage with 14.5V clamping and 1500W power rating, providing functional compatibility within the 8.5V class specification. The SMDJ8.5A (Alpha & Omega Semiconductor Inc.) maintains 8.5V standoff voltage but offers doubled peak pulse current (208.4A) and tripled peak pulse power (3000W), suitable for applications requiring higher transient energy absorption.

Compliance and Availability:

All substitute parts are active products with RoHS3 compliance and REACH unaffected status. Inventory availability ranges from 1023 to 20200 pieces across substitute options. Operating temperature ranges extend to -55°C minimum for all substitutes except the main part (-65°C), and SMCJ8.5A-TP extends to 175°C maximum.

Frequently Asked Questions (FAQ)

Q: Can SMCJ8.5A (EVVO Semi) directly replace SMCJ8.5AE3/TR13?

A: Yes. Both parts share 8.5V standoff voltage, 1500W peak pulse power, and DO-214AB packaging. The clamping voltage increases from 13.6V to 14.4V, and peak pulse current decreases from 110.3A to 104.2A. These variations remain within the functional tolerance of the 8.5V TVS diode class.

Q: What is the difference between SMCJ8.5A-TP and SMCJ8.5A-13-F?

A: Both parts maintain identical electrical specifications (8.5V standoff, 14.4V clamping, 104.2A peak pulse current, 1500W power). SMCJ8.5A-TP extends the operating temperature range to 175°C maximum, compared to 150°C for SMCJ8.5A-13-F. Manufacturers are Micro Commercial Co and Diodes Incorporated respectively.

Q: When should SMDJ8.5A be selected instead of direct substitutes?

A: SMDJ8.5A is selected when the application requires higher transient energy absorption. This part doubles peak pulse current to 208.4A and triples peak pulse power to 3000W while maintaining 8.5V standoff voltage. Use this substitute only if the circuit design specifically requires 3000W power dissipation capability.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed carry RoHS3 compliance certification and REACH unaffected status, matching the compliance profile of SMCJ8.5AE3/TR13.

Q: What packaging options are available for substitutes?

A: All substitute parts use DO-214AB or SMC package format, which are mechanically and electrically equivalent surface-mount packages. EVVO Semi SMCJ8.5A is supplied in Cut Tape & Digi-Reel packaging, while other substitutes use Tape & Reel packaging.

Q: Does the lower minimum operating temperature of substitutes (-55°C vs -65°C) affect compatibility?

A: For most applications, -55°C minimum operating temperature is sufficient. If the circuit operates below -55°C, the SMCJ8.5AE3/TR13 with -65°C rating must be retained. Verify application temperature requirements before substitution.

Q: Can 1.5SMC10A be used in place of SMCJ8.5AE3/TR13?

A: Yes, with verification. The 1.5SMC10A operates at 8.55V standoff voltage (0.05V higher than 8.5V nominal) with 14.5V clamping and 108A peak pulse current. This part is functionally compatible within the 8.5V TVS diode class and maintains 1500W power rating and DO-214AB packaging.
