SMBJ58CA Equivalent & Substitute Parts

Part Overview

The SMBJ58CA is a bidirectional transient voltage suppressor (TVS) diode manufactured by Taiwan Semiconductor Corporation in the DO-214AA (SMB) surface mount package. This component provides transient overvoltage protection for general-purpose applications with a 58V reverse standoff voltage and 93.6V maximum clamping voltage at peak pulse current. The part is currently active in production and RoHS3 compliant.

Equivalent and substitute parts are necessary when the primary manufacturer part becomes unavailable, when alternative packaging formats are required, or when sourcing from multiple qualified manufacturers is required for supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the SMBJ58CA is determined by electrical and mechanical parameter equivalence. All substitute parts must meet the following criteria:

Critical Electrical Parameters:

Voltage - Reverse Standoff (Typ): 58V
Voltage - Breakdown (Min): 64.4V
Voltage - Clamping (Max) @ Ipp: 93.6V
Current - Peak Pulse (10/1000µs): 6.4A
Power - Peak Pulse: 600W
Type: Zener
Bidirectional Channels: 1

Critical Mechanical Parameters:

Package / Case: DO-214AA, SMB
Mounting Type: Surface Mount

Compliance Parameters:

RoHS Status: ROHS3 Compliant (preferred)
Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are grouped into two categories: Direct Substitutes (identical electrical and mechanical specifications) and Similar Substitutes (equivalent electrical performance with potential packaging or temperature range variations).

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the SMBJ58CA?

A: A substitute part must maintain identical electrical parameters: 58V reverse standoff voltage, 93.6V maximum clamping voltage, 6.4A peak pulse current, and 600W peak pulse power. The package must be DO-214AA (SMB) surface mount. All critical parameters must match exactly.

Q: Are there differences in operating temperature ranges among substitutes?

A: Yes. The SMBJ58CA operates from -55°C to 150°C. The 1SMB58CA TR13 PBFREE extends the lower limit to -65°C, and the SMBJ58CA-TP extends the upper limit to 175°C. These variations do not affect substitution eligibility if your application operates within the substitute's temperature range.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging is supplied on individual tape segments suitable for manual handling or small-quantity applications. Tape & Reel packaging is supplied on continuous reels for automated assembly processes. Both formats contain identical components; the difference is in delivery and handling method only.

Q: Why is SMBJ58CA-13 not recommended as a substitute?

A: SMBJ58CA-13 is discontinued at DiGi Electronics and does not carry RoHS3 compliance certification. SMBJ58CA-13-F is the active replacement that maintains full RoHS3 compliance and is currently in production.

Q: Can I use SMBJ58CA-TP in applications with the original SMBJ58CA temperature specification?

A: Yes. SMBJ58CA-TP operates from -55°C to 175°C, which encompasses the original SMBJ58CA range of -55°C to 150°C. The extended upper temperature limit provides additional margin without affecting performance within the original specification range.

Q: Are all substitute parts RoHS3 compliant?

A: No. SMBJ58CA-13 is RoHS non-compliant. All other listed substitutes carry RoHS3 compliance certification. For applications requiring RoHS compliance, use only parts explicitly marked as ROHS3 Compliant.

Q: What is the significance of the "PBFREE" designation in 1SMB58CA TR13 PBFREE?

A: PBFREE indicates the part is manufactured without lead (Pb), consistent with RoHS3 requirements. This is a manufacturing process designation and does not affect electrical or mechanical compatibility.

Q: Can I mix different manufacturers' parts in the same design?

A: Yes. All listed substitutes meet identical electrical and mechanical specifications. They are functionally interchangeable within the same circuit design. Mixing manufacturers is acceptable from an engineering standpoint.

Q: Which substitute has the highest inventory availability?

A: SMBJ58CA-TP (Micro Commercial Co) has the highest inventory with 77,663 pcs in stock, followed by SMBJ58CA-13-F (Diodes Incorporated) with 38,100 pcs.
