Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5KP48AE3/TR13 are classified into two categories based on electrical parameter alignment:

Direct Equivalents maintain identical electrical specifications across all critical parameters: 48V reverse standoff voltage, 53.3V minimum breakdown voltage, 77.4V maximum clamping voltage, and 5000W peak pulse power rating. These parts differ only in packaging format (cut tape versus tape and reel) or manufacturer source, allowing direct functional replacement in circuit designs.

Higher-Performance Alternatives share the 48V reverse standoff voltage and general-purpose application classification but feature elevated peak pulse current ratings and power dissipation capabilities. These parts operate within the same voltage protection window but provide enhanced transient energy absorption capacity.

Substitution eligibility is determined by the following parameters:

• Voltage - Reverse Standoff (Typ): 48V
• Voltage - Breakdown (Min): 53.3V to 53.6V
• Voltage - Clamping (Max) @ Ipp: 77.4V to 81.6V
• Operating Temperature Range: -55°C to 175°C (TJ)
• Mounting Type: Through Hole
• Package / Case: P600 or R-6 Axial
• Type: Zener, Unidirectional
• RoHS Status: ROHS3 Compliant

Parameter Comparison

Engineering Selection Recommendations

Direct Functional Replacement: The 5KP48A-E3/54 (Vishay General Semiconductor - Diodes Division) and 5KP48A (Littelfuse Inc.) provide direct electrical equivalence to the 5KP48AE3/TR13. Both maintain identical voltage specifications (48V standoff, 77.4V clamping) and 5000W power rating. Selection between these options depends on packaging format availability: cut tape (CT) for automated assembly processes or tape and reel (TR) for high-volume production. All three parts maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Higher-Performance Alternatives: The 15KPA48A and 30KPA48A (MDE Semiconductor Inc) operate within the same 48V protection window but provide significantly elevated peak pulse current and power dissipation capacity (15kW and 30kW respectively). These parts are suitable for applications requiring enhanced transient energy absorption while maintaining the same reverse standoff voltage. Both maintain ROHS3 compliance and P600 axial through-hole packaging.

Packaging Considerations: The 5KP48A-TP (Micro Commercial Co) features R-6 axial packaging rather than standard P600, requiring mechanical footprint verification before selection. The 15KPA48A and 30KPA48A are supplied in bulk packaging format, necessitating tape and reel conversion for automated assembly compatibility.

Compliance Status: All substitute parts maintain active product status and ROHS3 compliance. The 5KP48AE3/TR13, 5KP48A-E3/54, and 5KP48A carry REACH Unaffected designation. The 15KPA48A and 30KPA48A indicate REACH status available upon request.

Frequently Asked Questions (FAQ)

Q: Can the 5KP48A-E3/54 directly replace the 5KP48AE3/TR13 in production assembly?

A: Yes. The 5KP48A-E3/54 provides identical electrical specifications (48V standoff, 77.4V clamping, 64.6A peak pulse, 5000W power). The primary difference is packaging format: the substitute is supplied in cut tape (CT) rather than tape and reel (TR). Automated pick-and-place equipment compatibility depends on feeder configuration for cut tape versus reel media.

Q: What is the functional difference between the 5KP48A and the 15KPA48A?

A: Both devices maintain 48V reverse standoff voltage and operate within the same overvoltage protection window. The 15KPA48A provides three times the peak pulse current (194.3A versus 64.6A) and three times the power dissipation capacity (15kW versus 5kW). Selection depends on transient energy levels in the target application. The 48V protection threshold remains constant across both parts.

Q: Are the 30KPA48A and 5KP48AE3/TR13 mechanically compatible?

A: Both devices use P600 axial through-hole packaging and are mechanically compatible for PCB mounting. However, the 30KPA48A is supplied in bulk packaging format rather than tape and reel, requiring manual tape conversion or alternative feeder setup for automated assembly processes.

Q: What does the clamping voltage specification indicate for substitution purposes?

A: The maximum clamping voltage (77.4V for the main part, 77.7V to 81.6V for higher-performance alternatives) represents the voltage level at which the TVS diode conducts peak pulse current. Variations within this range (77.4V to 81.6V) remain functionally acceptable for general-purpose protection applications sharing the same 48V standoff voltage. Clamping voltage differences do not prevent substitution when reverse standoff voltage is identical.

Q: Can the 5KP48A-TP be used as a substitute despite R-6 packaging instead of P600?

A: The 5KP48A-TP maintains identical electrical specifications and through-hole mounting type. However, R-6 and P600 represent different axial package geometries with distinct lead spacing and body dimensions. Mechanical compatibility requires PCB footprint verification before substitution. Electrical performance is equivalent; mechanical fit must be confirmed.

Q: What is the significance of the -55°C to 175°C operating temperature range for all substitute parts?

A: All listed substitute parts share this identical operating temperature range, indicating thermal compatibility across the entire product family. This parameter does not differentiate substitution eligibility. Selection based on temperature performance is not required when comparing parts within this group.

Q: Does higher peak pulse current in the 30KPA48A affect circuit protection characteristics?

A: No. The 30KPA48A maintains the same 48V reverse standoff voltage and operates within the same protection window as the 5KP48AE3/TR13. Higher peak pulse current (371.3A versus 64.6A) indicates greater transient energy absorption capacity, not different protection thresholds. The device clamps at comparable voltage levels while handling larger current pulses.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification. The 5KP48AE3/TR13, 5KP48A-E3/54, and 5KP48A also carry REACH Unaffected designation. The 15KPA48A and 30KPA48A indicate REACH status available upon request, requiring direct manufacturer contact for complete compliance documentation.
