Equivalent & Substitute Parts for SMBJ5377C/TR13 Zener Diode

Part Overview

SMBJ5377C/TR13 from Microchip Technology is an active, surface-mount Zener diode intended for voltage regulation and transient suppression in electronic circuits. It features a nominal Zener voltage of 91 V, 5 W power rating, ±2% tolerance, and DO-214AA (SMBJ) package suitable for tape and reel (TR) mounting. Finding alternative models is necessary to address requirements such as inventory optimization, compliance with environmental standards, or matching device specifications within existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped strictly based on the following allowed electrical and mechanical parameters: Zener voltage (91 V), package/case type (DO-214AA, SMB), mounting type (Surface Mount), category (Diodes, Zener), operating temperature range (-65°C ~ 150°C), and packaging format (Tape & Reel). Product status (active), regulatory compliance, and inventory availability are included by direct parameter comparison only.

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts can be based on product status (active), packaging type (Tape & Reel), mounting type (Surface Mount), and package/case (DO-214AA, SMB). Regulatory compliance differs: SMBJ5377C/TR13 is RoHS non-compliant, while SZ1SMB5948BT3G is ROHS3 compliant, which is relevant for applications requiring RoHS certification. Moisture Sensitivity Level and REACH status are equivalent across both parts.

Frequently Asked Questions (FAQ)

Q1: What are the primary substitution criteria for SMBJ5377C/TR13 Zener diode?
Substitution is based strictly on Zener voltage, power rating, package/case type, mounting method, operating temperature range, and product category.

Q2: Are the physical package and mounting type the same on listed substitutes?
Yes. Both SMBJ5377C/TR13 and SZ1SMB5948BT3G use DO-214AA, SMB case and surface-mount technology.

Q3: Does RoHS status affect compatibility?
RoHS status does not affect electrical compatibility but is required for environmental and regulatory compliance. SZ1SMB5948BT3G is ROHS3 compliant.

Q4: How do differences in power rating or impedance affect selection?
Only parameters explicitly provided are presented; selection must align with the specified power and impedance values as required for the application.

Q5: Is the substitute suitable in terms of operating temperature range?
Both parts operate between -65°C and 150°C, matching this key parameter.

Q6: Do substitute parts require modification to PCB footprint?
No. Both parts share the same DO-214AA, SMB package for direct substitution in compatible designs.
