Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6KE75A-TP are classified based on electrical parameter compatibility and mechanical interchangeability. The primary substitution criteria are:

Critical Matching Parameters:

• Voltage - Reverse Standoff (Typ): 64.0V to 64.1V
• Voltage - Clamping (Max) @ Ipp: 103V
• Package / Case: DO-204AC or DO-15 (axial through-hole)
• Mounting Type: Through Hole
• Type: Zener TVS Diode, Unidirectional

Secondary Compatibility Parameters:

• Current - Peak Pulse (10/1000µs): 5.0A to 6.1A
• Power - Peak Pulse: 500W to 600W
• Operating Temperature Range: -55°C to 175°C or -50°C to 175°C
• RoHS3 Compliance

Parts meeting all critical parameters are classified as direct equivalents or direct substitutes. Parts with minor variations in peak pulse current or power dissipation while maintaining identical voltage characteristics are classified as similar substitutes.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Preferred Substitutes):

P6KE75A-E3/54 (Vishay General Semiconductor) and TP6KE75A (Littelfuse Inc.) are direct equivalents to the P6KE75A-TP. Both parts match all critical electrical parameters, operate across the full -55°C to 175°C temperature range, maintain DO-15 package compatibility, and carry ROHS3 compliance certification. The P6KE75A-E3/54 is designated as part of the TransZorb® series, while the TP6KE75A carries AEC-Q101 automotive qualification.

Direct Substitute (Compatible Alternative):

P6KE75A (Fairchild Semiconductor) is a direct substitute with identical voltage characteristics and 600W peak pulse power rating. The operating temperature range is -50°C to 175°C, which is 5°C narrower at the lower limit compared to the main part. Peak pulse current is specified at 6.1A, which exceeds the main part's 5.8A rating.

Similar Substitute (Limited Application):

SA64A (Taiwan Semiconductor Corporation) is a similar substitute with matching voltage clamping characteristics but reduced peak pulse current (5A) and power dissipation (500W). This part is suitable for applications with lower transient current requirements. The reverse standoff voltage is specified at 64V, which is 0.1V lower than the main part.

All substitute parts are actively produced and RoHS3 compliant, ensuring regulatory compliance and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can P6KE75A-E3/54 be used as a direct replacement for P6KE75A-TP?

A: Yes. Both parts share identical voltage specifications (64.1V standoff, 103V clamping), peak pulse current (5.8A), power dissipation (600W), and operating temperature range (-55°C to 175°C). Both are packaged in DO-15 and carry ROHS3 compliance.

Q: What is the difference between P6KE75A (Fairchild) and P6KE75A-TP?

A: The Fairchild P6KE75A has an operating temperature range of -50°C to 175°C, which is 5°C narrower at the lower limit. Peak pulse current is rated at 6.1A versus 5.8A for the main part. Voltage characteristics are identical. This part is suitable for applications not requiring operation below -50°C.

Q: Is TP6KE75A suitable for automotive applications?

A: Yes. The TP6KE75A (Littelfuse) carries AEC-Q101 automotive qualification and meets all electrical requirements of the P6KE75A-TP. It is rated for -55°C to 175°C operation and is ROHS3 compliant.

Q: Can SA64A replace P6KE75A-TP in all applications?

A: SA64A is suitable for applications where peak transient current does not exceed 5A and peak pulse power does not exceed 500W. The reverse standoff voltage is 64V (0.1V lower) and clamping voltage is 103V (matching). Applications requiring the full 5.8A peak pulse current capability should use P6KE75A-TP or equivalent parts rated for 5.8A or higher.

Q: Are all substitute parts available in Cut Tape packaging?

A: P6KE75A-TP and TP6KE75A are available in Cut Tape (CT) packaging. P6KE75A-E3/54 is available in Cut Tape (CT). P6KE75A (Fairchild) packaging is not specified. SA64A is available in Tape & Reel (TR) packaging. Verify packaging availability with your supplier for your specific procurement requirements.

Q: Do all parts meet RoHS3 compliance?

A: P6KE75A-TP, P6KE75A-E3/54, SA64A, and TP6KE75A are all ROHS3 compliant. RoHS status for P6KE75A (Fairchild) is not specified in available documentation.
