SAC136-TP Equivalent & Substitute Parts

Part Overview

The SAC136-TP is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Micro Commercial Co, designed for general-purpose transient voltage protection in through-hole applications. This component features a 136V reverse standoff voltage with a 219V maximum clamping voltage and 2.7A peak pulse current capability in a DO-15 axial package. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are necessary when the original SAC136-TP is unavailable or when alternative manufacturers' components offer equivalent electrical performance with different packaging or availability profiles.

Substitute Part Grouping Explanation

Substitution eligibility for the SAC136-TP is determined by the following critical parameters:

Voltage - Reverse Standoff (Typ): 136V
Voltage - Clamping (Max) @ Ipp: 219V
Type: Zener, Unidirectional
Mounting Type: Through Hole
Applications: General Purpose

All substitute parts listed maintain identical reverse standoff voltage (136V) and clamping voltage (219V) specifications. Variations in peak pulse current (2.7A to 7.1A) and power dissipation (600W to 1500W) reflect different package geometries and thermal capabilities but do not affect the core voltage protection function. Package variations between DO-15 and DO-201 are both axial through-hole configurations suitable for equivalent circuit board layouts.

Engineering Selection Recommendations

Direct Package Equivalents (DO-15 / DO-204AC): P6KE160A (Fairchild) and P6KE160A-G (Comchip) maintain identical DO-15 package geometry to the SAC136-TP, enabling direct board-level substitution without layout modification. Both parts are ROHS3 compliant (P6KE160A-G) or meet equivalent standards. Peak pulse current specifications (2.8A and 2.74A respectively) closely match the original 2.7A rating.

Higher Power Capability Alternatives (DO-201 / DO-27): 1.5KE160A (Diotec) and 1.5KE160A-E3/54 (Vishay) provide increased peak pulse current (7.1A and 6.8A) and power dissipation (1500W) in larger DO-201 package geometry. The 1.5KE160A-E3/54 carries ROHS3 compliance and REACH unaffected status. These alternatives are suitable for applications requiring higher transient energy absorption, though board layout accommodation for the larger package is required.

Compliance Considerations: The 1.5KE160A-E3/54 (Vishay) offers the broadest compliance profile with ROHS3 certification and REACH unaffected status, matching the original part's regulatory standing. The P6KE160A-G (Comchip) also maintains ROHS3 compliance with a narrower upper operating temperature limit of 150°C compared to 175°C for other options.

Frequently Asked Questions (FAQ)

Q: Can P6KE160A or P6KE160A-G be used as direct replacements for SAC136-TP? A: Yes. Both parts maintain identical voltage specifications (136V standoff, 219V clamping), unidirectional zener type, and DO-15 package configuration. Peak pulse current ratings (2.8A and 2.74A) are within 4% of the original 2.7A specification, making them functionally equivalent for general-purpose transient suppression circuits.

Q: What is the advantage of using 1.5KE160A or 1.5KE160A-E3/54 over the original SAC136-TP? A: The 1.5KE series offers significantly higher peak pulse current (6.8A to 7.1A) and power dissipation capability (1500W versus unspecified for SAC136-TP). These characteristics enable protection of higher-energy transient events. The trade-off is a larger DO-201 package requiring board layout modification.

Q: Are there temperature rating differences between substitute parts? A: Yes. The SAC136-TP, 1.5KE160A, 1.5KE160A-E3/54, and P6KE160A all support -40°C to 175°C or lower minimum temperatures. The P6KE160A-G has a reduced upper limit of 150°C. For applications requiring full -55°C to 175°C range, the 1.5KE160A-E3/54 is the optimal choice.

Q: Do package differences affect circuit board compatibility? A: DO-15 and DO-201 packages are both axial through-hole configurations with different physical dimensions. DO-15 (SAC136-TP, P6KE160A, P6KE160A-G) fits existing SAC136-TP footprints without modification. DO-201 (1.5KE160A, 1.5KE160A-E3/54) requires larger pad spacing and may necessitate board layout changes.

Q: Which substitute part has the best regulatory compliance profile? A: The 1.5KE160A-E3/54 (Vishay) carries ROHS3 compliance and REACH unaffected status, matching the original SAC136-TP's regulatory standing. The P6KE160A-G (Comchip) also maintains ROHS3 compliance.
