P6SMB62AT3 Equivalent & Substitute Parts

Part Overview

The P6SMB62AT3 is a unidirectional transient voltage suppressor (TVS) diode manufactured by onsemi, designed for surface mount applications in the DO-214AA (SMB) package. This component provides 53V reverse standoff voltage with 85V maximum clamping voltage and 7.1A peak pulse current capability. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain electrical and mechanical compatibility for new designs and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P6SMB62AT3 is determined by strict equivalence in the following electrical parameters: reverse standoff voltage (53V nominal), breakdown voltage minimum (58.9V), clamping voltage maximum (85V), and peak pulse current rating (7.1A). Mechanical compatibility requires identical or functionally equivalent package designation (DO-214AA/SMB surface mount). All substitute parts must maintain unidirectional (single channel) TVS diode topology. Parts are grouped by their ability to satisfy these core requirements while considering product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Electrical & Package Match):

1KSMB62A (Taiwan Semiconductor Corporation) and P6SMB62A (Thinking Electronics Industrial Co.) provide direct electrical equivalence with identical reverse standoff voltage (53V), breakdown voltage (58.9V), and clamping voltage (85V). Both maintain DO-214AA/SMB package compatibility. The 1KSMB62A offers higher peak pulse current (11.8A) and power dissipation (1kW), providing design margin. Both parts are active with current RoHS compliance certifications, eliminating obsolescence risk.

Secondary Substitutes (Voltage Tolerance):

SMBJ54A (MDD) and PTVS54VP1UP,115 (NXP) exhibit 1V higher reverse standoff voltage (54V) and breakdown voltage (60V) with marginally lower peak pulse current (6.9A). These parts remain functionally compatible for applications where the voltage differential does not exceed system tolerance. PTVS54VP1UP,115 uses SOD-128 package, requiring PCB layout modification. Both parts are active and RoHS compliant.

Limited Substitution (Incomplete Data):

TVP06B620A-G (Comchip) lacks published electrical parameters (standoff voltage, breakdown voltage, clamping voltage, peak pulse current), preventing full electrical verification. This part is suitable only when complete datasheet specifications can be obtained and verified against application requirements.

Frequently Asked Questions (FAQ)

Q: Can I use 1KSMB62A as a direct replacement for P6SMB62AT3?

A: Yes. The 1KSMB62A maintains identical reverse standoff voltage (53V), breakdown voltage (58.9V), and clamping voltage (85V). The higher peak pulse current (11.8A vs. 7.1A) and power rating (1kW vs. 600W) provide additional design margin. Both use DO-214AA/SMB packages. The part is active with current RoHS compliance.

Q: What is the difference between P6SMB62A and 1KSMB62A?

A: Both parts share identical electrical specifications (53V standoff, 58.9V breakdown, 85V clamping). The 1KSMB62A provides higher peak pulse current (11.8A vs. 7.06A) and power dissipation (1kW vs. 600W). Manufacturers differ: P6SMB62A is from Thinking Electronics, 1KSMB62A is from Taiwan Semiconductor Corporation. Both are active and RoHS compliant.

Q: Can SMBJ54A replace P6SMB62AT3?

A: SMBJ54A is functionally compatible with voltage tolerance consideration. It maintains DO-214AA/SMB package compatibility and 600W power rating. However, reverse standoff voltage is 54V (1V higher) and peak pulse current is 6.9A (0.2A lower). Use only when application specifications permit 1V voltage margin and lower current rating.

Q: Why does PTVS54VP1UP,115 use a different package?

A: PTVS54VP1UP,115 uses SOD-128 package instead of DO-214AA/SMB. This requires PCB layout modification and different land pattern design. Electrical specifications are similar (54V standoff, 87.1V clamping, 6.9A peak pulse). Use only when package change is acceptable for your design.

Q: What does "obsolete" status mean for P6SMB62AT3?

A: Obsolete status indicates the part is no longer manufactured by onsemi and will not be restocked. Existing inventory may be available from distributors, but long-term supply is not guaranteed. Active equivalent parts (1KSMB62A, P6SMB62A, SMBJ54A) ensure continued availability for production and future designs.

Q: Is TVP06B620A-G a suitable substitute?

A: TVP06B620A-G cannot be confirmed as suitable without complete electrical parameter data. Published specifications lack reverse standoff voltage, breakdown voltage, clamping voltage, and peak pulse current values. Obtain full datasheet specifications and verify against application requirements before selection.

Q: Do all substitute parts meet automotive qualification requirements?

A: P6SMB62AT3 carries AEC-Q101 automotive qualification. PTVS54VP1UP,115 also carries AEC-Q101 qualification. Other substitutes (1KSMB62A, P6SMB62A, SMBJ54A, TVP06B620A-G) do not list automotive qualification in provided specifications. For automotive applications, verify qualification status with manufacturer datasheets.
