SA5V0A-T Transient Voltage Suppressor (TVS) Diode — Equivalent & Substitute Parts

Part Overview

The SA5V0A-T is a unidirectional Zener-type transient voltage suppressor diode manufactured by Diodes Incorporated, designed for general-purpose overvoltage protection in through-hole DO-15 packaging. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The SA5V0A-T operates across a temperature range of -65°C to 175°C (TJ) and meets ROHS3 compliance with unlimited moisture sensitivity rating (MSL 1).

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SA5V0A-T is determined by strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Voltage - Reverse Standoff (Typ): 5V
• Voltage - Clamping (Max) @ Ipp: 9.2V
• Current - Peak Pulse (10/1000µs): 54.3A ± tolerance
• Power - Peak Pulse: 500W
• Mounting Type: Through Hole
• Package / Case: DO-204AC, DO-15, or Axial equivalent
• Type: Zener, Unidirectional (1 channel)

Substitute Categories:

Category A — Direct Electrical & Mechanical Equivalents (Active Status) Parts meeting all primary criteria with identical or superior electrical performance and active product status:

• SA5.0A (Taiwan Semiconductor Corporation)
• SA5.0A-E3/54 (Vishay General Semiconductor - Diodes Division)
• SA5.0AHE3/54 (Vishay General Semiconductor - Diodes Division, AEC-Q101 qualified)
• P5KE5.0A-BP (Micro Commercial Co)
• P5KE5.0A-AP (Micro Commercial Co)
• P5KE5.0A-TP (Micro Commercial Co)
• SA5.0A-B (Littelfuse Inc.)
• SA5.0A-TP (Micro Commercial Co)

Category B — Electrical Equivalents with Parameter Variance (Active Status) Parts meeting core voltage and power specifications with acceptable current or clamping voltage variation:

• SAC5.0 (Littelfuse Inc.) — 10V clamping, 44A peak pulse
• SAC5.0-B (Littelfuse Inc.) — 10V clamping, 44A peak pulse

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance): Select from Category A parts when the original -65°C lower temperature bound is not required. SA5.0A-E3/54 and SA5.0AHE3/54 from Vishay offer ROHS3 compliance and established supply chains. SA5.0AHE3/54 includes AEC-Q101 automotive qualification for applications requiring automotive-grade reliability.

For Extended Temperature Range (-65°C Lower Bound): P5KE5.0A-BP, P5KE5.0A-AP, and P5KE5.0A-TP from Micro Commercial Co maintain the -65°C to 175°C operating range. These parts are manufacturer-recommended equivalents with identical electrical specifications.

For High-Volume or Cost-Optimized Applications: SA5.0A from Taiwan Semiconductor Corporation offers the highest inventory availability (300,100 pcs) with 57A peak pulse current, exceeding the original 54.3A specification. Operating temperature is -55°C to 175°C.

For Compliance-Critical Applications: All Category A parts carry ROHS3 compliance. SA5.0AHE3/54 adds AEC-Q101 automotive qualification for regulated environments.

For Relaxed Clamping Voltage Tolerance: SAC5.0 and SAC5.0-B are acceptable where 10V clamping voltage (versus 9.2V) and 44A peak pulse (versus 54.3A) meet circuit requirements. These parts reduce peak current handling but maintain 5V reverse standoff and 500W peak power dissipation.

Frequently Asked Questions (FAQ)

Q: Can SA5.0A replace SA5V0A-T directly? A: Yes. SA5.0A matches all critical electrical parameters (5V standoff, 9.2V clamping, 54.3A peak pulse equivalent via 57A rating) and operates in the same through-hole DO-15 package. The operating temperature range is -55°C to 175°C versus the original -65°C to 175°C; verify this meets your application requirements.

Q: What is the difference between SA5.0A-E3/54 and SA5.0AHE3/54? A: Both parts are electrically identical with 5V standoff, 9.2V clamping, and 54.3A peak pulse. SA5.0AHE3/54 includes AEC-Q101 automotive qualification and is supplied in Tape & Reel packaging, while SA5.0A-E3/54 is supplied in Cut Tape. Select SA5.0AHE3/54 for automotive or regulated applications.

Q: Why do P5KE5.0A-BP, P5KE5.0A-AP, and P5KE5.0A-TP have different suffixes? A: The suffixes denote packaging and tape configuration: BP (Bulk), AP (Bulk), and TP (Bulk). All three are electrically identical and maintain the -65°C to 175°C operating range of the original part.

Q: Can I use SAC5.0 instead of SA5V0A-T? A: SAC5.0 is acceptable only if your circuit tolerates 10V clamping voltage (versus 9.2V) and 44A peak pulse (versus 54.3A). The 5V reverse standoff and 500W peak power remain equivalent. Verify these relaxed specifications do not compromise overvoltage protection margins.

Q: What does ROHS3 compliance mean for this part? A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive 3, restricting lead, cadmium, mercury, and other hazardous materials. All recommended Category A substitutes carry ROHS3 compliance.

Q: Is the operating temperature range critical for my selection? A: If your application operates below -55°C, select P5KE5.0A-BP, P5KE5.0A-AP, or P5KE5.0A-TP, which maintain the -65°C lower bound. For standard industrial applications (-55°C to 175°C), all Category A parts are suitable.

Q: What is the difference between DO-15 and DO-204AC packaging? A: DO-15 and DO-204AC are equivalent axial through-hole packages for diodes. Parts listed as DO-204AC (DO-15) use the same physical form factor and are mechanically interchangeable.
