TPSMD16A Equivalent & Substitute Parts

Part Overview

The TPSMD16A is a unidirectional transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for surface mount applications in the DO-214AB (SMC) package. This component provides transient overvoltage protection with a 16V reverse standoff voltage and 26V maximum clamping voltage. The part is actively produced and carries automotive-grade qualification (AEC-Q101), making it suitable for demanding protection applications. Equivalent parts are identified to support supply chain flexibility, design continuity, and procurement optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPSMD16A are qualified based on electrical parameter equivalence and mechanical compatibility. The following criteria determine substitutability:

Electrical Parameters (Must Match):

• Voltage - Reverse Standoff (Typ): 16V
• Voltage - Breakdown (Min): 17.8V
• Voltage - Clamping (Max) @ Ipp: 26V
• Current - Peak Pulse (10/1000µs): 115.4A
• Power - Peak Pulse: 3000W

Mechanical Parameters (Must Match):

• Unidirectional Channels: 1
• Package / Case: DO-214AB or SMC equivalent
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

The identified substitutes meet all electrical and mechanical requirements, ensuring direct functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts are actively produced and ROHS3 compliant, supporting long-term supply availability. The TPSMD16A carries automotive-grade qualification (AEC-Q101), which is the highest reliability standard among the three options. The SMDJ16A (Alpha & Omega) operates across a narrower temperature range (-55 to 150°C) compared to the TPSMD16A and 3SMC16A TR13 PBFREE (both -65 to 150°C), which may be a consideration for applications requiring extended low-temperature performance.

For applications requiring automotive-grade certification, the TPSMD16A remains the primary choice. For general-purpose applications where automotive qualification is not required, the SMDJ16A and 3SMC16A TR13 PBFREE provide equivalent electrical performance and full compliance with environmental standards.

Frequently Asked Questions (FAQ)

Q: Can SMDJ16A replace TPSMD16A in automotive applications? A: SMDJ16A provides identical electrical performance and RoHS3 compliance. However, TPSMD16A carries AEC-Q101 automotive qualification, which SMDJ16A does not. Use SMDJ16A only in non-automotive applications or where automotive qualification is not contractually required.

Q: What is the difference between DO-214AB and SMC packaging? A: DO-214AB and SMC refer to the same physical package format for surface mount diodes. These designations are interchangeable in this product category.

Q: Are there temperature range differences between substitutes? A: Yes. SMDJ16A operates from -55 to 150°C, while TPSMD16A and 3SMC16A TR13 PBFREE both operate from -65 to 150°C. For applications requiring operation below -55°C, use TPSMD16A or 3SMC16A TR13 PBFREE.

Q: Do all substitutes meet RoHS and REACH requirements? A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Can these parts be used interchangeably on the same PCB? A: Yes. All parts share identical electrical parameters, unidirectional channel configuration, and surface mount DO-214AB/SMC package compatibility, enabling direct PCB substitution without circuit redesign.
