SMBJ160C Equivalent & Substitute Parts

Part Overview

The SMBJ160C is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose transient voltage protection in surface-mount applications. This component operates with a reverse standoff voltage of 160V and provides clamping protection at 271.95V maximum. The SMBJ160C is currently listed as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SMBJ160C are qualified based on the following electrical and mechanical parameters:

• Reverse Standoff Voltage: Must be 160V (Typ)
• Package / Case: Must be DO-214AA, SMB (surface mount)
• Current - Peak Pulse (10/1000µs): Must be 2.3A
• Power - Peak Pulse: Must be 600W
• Type: Must be Zener diode
• Bidirectional Channels: Must be 1
• Mounting Type: Must be Surface Mount

The substitute parts identified—SMBJ160CA and SMBJ160CA-E3/52—meet all these electrical and mechanical requirements. Variations in clamping voltage (259V vs. 271.95V) and breakdown voltage remain within acceptable tolerance ranges for the same device class and application category.

Parameter Comparison

Engineering Selection Recommendations

SMBJ160CA (Taiwan Semiconductor Corporation) and SMBJ160CA-E3/52 (Vishay General Semiconductor - Diodes Division) are both qualified substitutes for the obsolete SMBJ160C.

Both substitute parts are currently in active production status, ensuring long-term availability and supply chain continuity. Both maintain ROHS3 compliance and carry unlimited moisture sensitivity level (MSL 1) ratings, matching the original component's environmental qualifications.

The SMBJ160CA-E3/52 (Vishay) offers significantly higher inventory availability (45,400 pcs) compared to the Taiwan Semiconductor variant (1,700 pcs), making it the preferred choice for high-volume production requirements. Both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes.

The operating temperature range for both substitutes extends to -55°C minimum, compared to the original -65°C minimum. Applications requiring operation below -55°C must evaluate this specification against system requirements.

Frequently Asked Questions (FAQ)

Q: Can SMBJ160CA and SMBJ160CA-E3/52 be used interchangeably with SMBJ160C?

A: Yes. Both substitute parts meet the core electrical specifications: 160V reverse standoff voltage, 2.3A peak pulse current, 600W peak pulse power, and DO-214AA SMB package configuration. Both are Zener-type, single-channel TVS diodes suitable for general-purpose transient voltage suppression.

Q: What is the difference between SMBJ160CA and SMBJ160CA-E3/52?

A: Both parts are electrically identical with matching reverse standoff voltage (160V), peak pulse current (2.3A), and power rating (600W). The primary differences are manufacturer (Taiwan Semiconductor vs. Vishay), packaging designation (SMB vs. SMBJ), and inventory availability. The "-E3/52" suffix indicates Vishay's specific packaging and tape configuration.

Q: Are there temperature range differences I should consider?

A: The original SMBJ160C operates from -65°C to 150°C. Both substitute parts operate from -55°C to 150°C. If your application requires operation below -55°C, the original specification cannot be maintained with these substitutes.

Q: Do the substitute parts have different clamping voltages?

A: Yes. The SMBJ160C specifies 271.95V maximum clamping voltage, while both substitutes specify 259V maximum clamping voltage. Both remain within the same device class and application category for general-purpose transient suppression at 160V standoff.

Q: Are both substitutes available in the same package?

A: Both substitute parts use the DO-214AA SMB surface-mount package, matching the original SMBJ160C package configuration. Both are supplied in Tape & Reel (TR) format for automated assembly.

Q: Which substitute should I select for new designs?

A: Selection depends on procurement requirements. SMBJ160CA-E3/52 (Vishay) offers superior inventory availability (45,400 pcs) and is manufacturer-recommended. SMBJ160CA (Taiwan Semiconductor) is an alternative with active product status and ROHS3 compliance. Both are electrically qualified substitutes.
