SMBJ16CE3/TR13 Equivalent & Substitute Parts

Part Overview

The SMBJ16CE3/TR13 is an active status Transient Voltage Suppressor (TVS) diode manufactured by Microchip Technology. This surface mount component operates at a reverse standoff voltage of 16V with a clamping voltage of 28.8V at peak pulse current. TVS diodes provide transient protection in general-purpose applications by clamping voltage spikes to safe levels. Substitute parts are necessary when the primary part reaches end-of-life status, inventory depletion, or alternative packaging configurations are required for manufacturing flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ16CE3/TR13 are qualified when they maintain electrical compatibility across the following critical parameters:

• Voltage - Reverse Standoff: 16V (primary protection threshold)
• Voltage - Breakdown (Min): 17.8V (trigger point)
• Voltage - Clamping (Max) @ Ipp: 26V to 28.8V (acceptable range for transient suppression)
• Current - Peak Pulse (10/1000µs): Minimum 20.8A (pulse handling capability)
• Power - Peak Pulse: 600W (dissipation rating)
• Operating Temperature Range: Minimum -55°C to 150°C or broader
• Mounting Type: Surface Mount
• Package / Case: DO-214AA / SMB (mechanical compatibility)
• RoHS Compliance: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

All identified substitute parts meet these criteria and are qualified for direct replacement based on electrical parameters and packaging compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance with MSL-1 ratings, confirming suitability for manufacturing environments without moisture sensitivity restrictions.

SMBJ16CA (EVVO Semi): Electrically equivalent with 23.1A peak pulse capability, exceeding the 20.8A requirement. Operating temperature range matches the original at -65°C to 150°C. High inventory availability (29200 units) supports supply chain continuity.

SMBJ16CA-13-F (Diodes Incorporated): Electrically equivalent with 23.1A peak pulse capability. Operating temperature range of -55°C to 150°C is acceptable for most general-purpose applications. Largest inventory availability (53300 units) provides maximum supply security.

SMBJ16CA-TP (Micro Commercial Co): Electrically equivalent with 23.1A peak pulse capability and extended operating temperature range of -55°C to 175°C. Available in Tape & Reel packaging matching the original. Suitable for applications requiring expanded temperature performance.

All substitute parts operate with clamping voltages of 26V, which is within acceptable tolerance relative to the 28.8V specification and meets transient suppression requirements for 16V standoff protection circuits.

Frequently Asked Questions (FAQ)

Q: Can SMBJ16CA parts substitute for SMBJ16CE3/TR13 in surface mount applications? A: Yes. All substitute parts are surface mount components in DO-214AA / SMB packages with compatible footprints. Electrical parameters for reverse standoff voltage (16V), breakdown voltage (17.8V), and peak pulse current (≥20.8A) are maintained across all alternatives.

Q: Why do substitute parts have lower clamping voltages (26V vs 28.8V)? A: The clamping voltage specification indicates the maximum voltage at peak pulse current (Ipp). Substitute parts rated at 26V clamp voltage operate within acceptable tolerance for circuits designed around 16V standoff protection. Both voltage levels suppress transients effectively in general-purpose applications.

Q: Are temperature range differences significant? A: Substitute parts from Diodes Incorporated and Micro Commercial Co specify minimum operating temperatures of -55°C compared to -65°C on the Microchip original. EVVO Semi maintains -65°C. For applications requiring operation below -55°C, the Microchip original or EVVO Semi SMBJ16CA are required. Micro Commercial Co's SMBJ16CA-TP extends the upper limit to 175°C, supporting high-temperature environments.

Q: Does packaging format affect compatibility? A: All parts are available in standard Tape & Reel or Cut Tape / Digi-Reel formats compatible with automated assembly. Format selection depends on manufacturing equipment capabilities, not electrical performance. The DO-214AA / SMB package dimensions are standardized across all manufacturers.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 compliance and MSL-1 ratings, confirming compatibility with lead-free assembly processes and unrestricted moisture sensitivity handling.

Q: Which substitute offers the best inventory availability? A: SMBJ16CA-13-F from Diodes Incorporated offers the highest stock level at 53300 units, followed by EVVO Semi SMBJ16CA at 29200 units. Both support large volume procurement without supply delays.
