P1300SA Equivalent & Substitute Parts

Part Overview

The P1300SA is a Transient Voltage Suppressor (TVS) thyristor manufactured by Littelfuse Inc. in the SIDACtor® series. This component is rated for 120V off-state voltage with 150A peak pulse current capability in a DO-214AA (SMB) surface mount package. The P1300SA is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P1300SA are selected based on electrical and mechanical compatibility within the following criteria:

Primary Substitution Parameters:

• Voltage - Off State: 120V (exact match required)
• Voltage - Breakover: 160V (exact match required)
• Current - Peak Pulse (8/20µs): 150A (exact match required)
• Package / Case: DO-214AA, SMB (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Parameters:

• Current - Hold (Ih): 150mA (exact match required)
• Number of Elements: 1 (exact match required)

Parts meeting these criteria are classified as direct electrical and mechanical equivalents. Variations in capacitance, on-state voltage, or 10/1000µs pulse current do not preclude substitution when primary parameters align.

Parameter Comparison

Engineering Selection Recommendations

P1300SALRP (Littelfuse Inc.): This part is a direct Littelfuse equivalent with identical electrical specifications to the P1300SA. It maintains the same voltage ratings (120V off-state, 160V breakover) and current ratings (150A peak pulse at 8/20µs). The P1300SALRP is active in production status and ROHS3 compliant, addressing the obsolescence and compliance limitations of the original P1300SA. Packaging is supplied as Tape & Reel (TR) for automated assembly. This is the preferred substitute when maintaining the same manufacturer is required.

SMTPA120 (STMicroelectronics): This part provides electrical equivalence with identical voltage and current specifications to the P1300SA. The SMTPA120 is active in production, ROHS3 compliant, and available in Tape & Reel packaging. Capacitance is lower (30pF versus 40pF), and the 10/1000µs pulse current is slightly higher (50A versus 45A). These variations remain within acceptable substitution parameters for the same electrical class.

SMTPA130 (STMicroelectronics): This part differs in voltage rating, with 130V off-state and 173V breakover specifications compared to the P1300SA's 120V and 160V ratings. The SMTPA130 maintains the same 150A peak pulse current (8/20µs) and identical current-hold specification. This part is suitable only for applications where the higher voltage rating is acceptable or beneficial. It is active in production and ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can P1300SALRP be used as a direct replacement for P1300SA? A: Yes. The P1300SALRP is electrically and mechanically identical to the P1300SA, with matching voltage ratings (120V off-state, 160V breakover) and current specifications (150A at 8/20µs). Both use the DO-214AA SMB package. The primary advantage of P1300SALRP is active production status and ROHS3 compliance.

Q: What is the difference between SMTPA120 and SMTPA130? A: The SMTPA120 matches the P1300SA voltage specifications exactly (120V off-state, 160V breakover). The SMTPA130 has higher voltage ratings (130V off-state, 173V breakover). Both maintain 150A peak pulse current at 8/20µs. Selection depends on the application's voltage requirements.

Q: Are there packaging differences between these substitutes? A: The P1300SA is supplied in bulk packaging. Both P1300SALRP and the STMicroelectronics parts (SMTPA120, SMTPA130) are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.

Q: Does capacitance variation affect substitution suitability? A: The P1300SA has 40pF capacitance, while P1300SALRP has 45pF and the STMicroelectronics parts have 30pF. These variations do not preclude substitution when all primary electrical parameters (voltage and current ratings) match the application requirements.

Q: What compliance certifications apply to these parts? A: The P1300SA is RoHS non-compliant. All substitute parts (P1300SALRP, SMTPA120, SMTPA130) are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for new designs.
