MXLSMBJ16AE3 Equivalent & Substitute Parts

Part Overview

The MXLSMBJ16AE3 is a unidirectional Zener transient voltage suppressor (TVS) diode manufactured by Microchip Technology. This surface mount component is designed for general-purpose transient voltage protection applications, featuring a 16V reverse standoff voltage and 26V maximum clamping voltage. The device is qualified to MIL-PRF-19500 military standards and operates across an extended temperature range of -65°C to 150°C. As an active product with 1114 units in stock, the MXLSMBJ16AE3 remains available through standard distribution channels. Equivalent and substitute parts are identified based on matching electrical performance parameters and compatible packaging specifications.

Substitute Part Grouping Explanation

Substitute parts for the MXLSMBJ16AE3 are identified based on electrical parameter equivalence within the transient voltage suppressor category. The substitution criteria are strictly limited to the following parameters:

• Voltage - Reverse Standoff (Typ): 16V
• Voltage - Breakdown (Min): 17.8V
• Voltage - Clamping (Max) @ Ipp: 26V
• Current - Peak Pulse (10/1000µs): 23.1A
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA or SMB
• Mounting Type: Surface Mount
• Type: Zener
• Unidirectional Channels: 1

Parts meeting all electrical specifications and compatible packaging are classified as direct substitutes. Operating temperature range variations and product status differences do not disqualify substitution eligibility when electrical parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

The SMBJ16A-13 manufactured by Diodes Incorporated is electrically equivalent to the MXLSMBJ16AE3 across all critical transient voltage suppression parameters. Both devices share identical voltage ratings, peak pulse current specifications, and power dissipation capabilities. Package compatibility is confirmed for both DO-214AA and SMB surface mount configurations.

The primary distinction between these parts is product status and operating temperature range. The MXLSMBJ16AE3 maintains active product status with military-grade qualification (MIL-PRF-19500) and an extended lower temperature limit of -65°C, compared to the SMBJ16A-13 lower limit of -55°C. The SMBJ16A-13 is discontinued at DiGi Electronics, which may impact long-term availability.

For applications requiring military qualification or extended low-temperature operation below -55°C, the MXLSMBJ16AE3 is the appropriate selection. For general-purpose applications within the -55°C to 150°C temperature range where military qualification is not required, the SMBJ16A-13 provides electrical equivalence. Both devices maintain identical RoHS non-compliance status, REACH unaffected classification, and export control coding (EAR99).

Frequently Asked Questions (FAQ)

Q: Can the SMBJ16A-13 be used as a direct replacement for the MXLSMBJ16AE3?

A: The SMBJ16A-13 is electrically equivalent to the MXLSMBJ16AE3 for all transient voltage suppression parameters, including voltage ratings, peak pulse current, and power dissipation. Both devices use compatible DO-214AA/SMB surface mount packaging. Substitution is valid for applications operating within the -55°C to 150°C temperature range. Applications requiring operation below -55°C or military qualification require the MXLSMBJ16AE3.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching the following parameters: Voltage - Reverse Standoff (16V), Voltage - Breakdown (17.8V minimum), Voltage - Clamping (26V maximum at Ipp), Current - Peak Pulse (23.1A at 10/1000µs), and Power - Peak Pulse (600W). Package compatibility (DO-214AA or SMB) and mounting type (surface mount) must also align.

Q: Are there packaging differences between these parts?

A: Both the MXLSMBJ16AE3 and SMBJ16A-13 use DO-214AA and SMB package designations. No physical packaging differences exist that would prevent direct board-level substitution.

Q: What is the significance of the product status difference?

A: The MXLSMBJ16AE3 is listed as active, indicating ongoing availability through distribution channels. The SMBJ16A-13 is discontinued at DiGi Electronics, which may limit future procurement options. For new designs or long-term production requirements, the active status of the MXLSMBJ16AE3 provides supply chain continuity.

Q: Does military qualification affect substitution decisions?

A: Military qualification (MIL-PRF-19500) is specific to the MXLSMBJ16AE3. Applications requiring military-grade components must use the MXLSMBJ16AE3. For non-military applications, military qualification does not impact substitution eligibility.

Q: What is the operating temperature difference between these parts?

A: The MXLSMBJ16AE3 operates from -65°C to 150°C, while the SMBJ16A-13 operates from -55°C to 150°C. The MXLSMBJ16AE3 supports 10°C lower minimum temperature operation. Applications requiring operation below -55°C must use the MXLSMBJ16AE3.
