MMPQ3906 TR13 Equivalent & Substitute Parts

Part Overview

The MMPQ3906 TR13 is a Bipolar (BJT) Transistor Array containing 4 PNP transistors in a 16-SOIC surface mount package. Manufactured by Central Semiconductor Corp, this component is rated for 40V collector-emitter breakdown voltage, 200mA maximum collector current, and 1W power dissipation with a transition frequency of 450MHz. The part is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMPQ3906 TR13 is determined by strict electrical and mechanical parameter matching within the PNP quad transistor array category. The following parameters establish substitution compatibility:

Critical Matching Parameters:

• Transistor configuration: 4 PNP (Quad) array
• Maximum collector current: 200mA
• Collector-emitter breakdown voltage: 40V
• Saturation voltage: 400mV @ 5mA, 50mA
• DC current gain (hFE): minimum 100 @ 10mA, 1V
• Power dissipation: 1W
• Package type: 16-SOIC surface mount
• Operating temperature range: -55°C ~ 150°C

The MMPQ3906 from onsemi meets all critical electrical parameters. The transition frequency specification (200MHz for onsemi versus 450MHz for the original) represents a lower performance characteristic in the substitute, which is acceptable for applications not requiring the higher frequency capability of the original part.

Parameter Comparison

Engineering Selection Recommendations

The MMPQ3906 from onsemi is a direct electrical and mechanical substitute for the obsolete MMPQ3906 TR13 from Central Semiconductor Corp. Both parts share identical specifications for collector current, breakdown voltage, saturation voltage, current gain, power rating, package configuration, and operating temperature range.

The onsemi MMPQ3906 carries Active product status, ensuring continued availability and manufacturing support. The part is ROHS3 compliant, meeting current environmental and regulatory requirements, whereas the original Central Semiconductor part is RoHS non-compliant. Both parts maintain REACH Unaffected status and EAR99 export classification.

The transition frequency difference (200MHz versus 450MHz) reflects a lower maximum operating frequency in the onsemi substitute. This parameter difference is non-critical for applications operating below 200MHz. For circuits requiring the full 450MHz transition frequency capability, this substitution is not suitable.

Frequently Asked Questions (FAQ)

Q: Can the onsemi MMPQ3906 directly replace the Central Semiconductor MMPQ3906 TR13 in existing designs?

A: Yes, for applications operating at transition frequencies up to 200MHz. The electrical parameters—collector current, breakdown voltage, saturation voltage, and current gain—are identical. The 16-SOIC package dimensions and pin configuration are identical, enabling direct PCB-level substitution.

Q: What is the significance of the transition frequency difference?

A: The original part specifies 450MHz transition frequency; the onsemi substitute specifies 200MHz. This represents the maximum frequency at which the transistor maintains specified gain characteristics. Applications requiring operation above 200MHz must evaluate circuit performance with the lower frequency specification.

Q: Are there packaging or moisture sensitivity differences?

A: The onsemi MMPQ3906 is supplied in Cut Tape (CT) and Digi-Reel packaging with MSL 3 (168 Hours) moisture sensitivity. The original part specifies MSL 1 (Unlimited). Both are surface mount 16-SOIC packages with identical physical dimensions (0.154", 3.90mm width).

Q: What compliance advantages does the onsemi part offer?

A: The onsemi MMPQ3906 is ROHS3 compliant, meeting current environmental regulations. The original Central Semiconductor part is RoHS non-compliant. Both maintain REACH Unaffected status and EAR99 export classification.

Q: Is the onsemi MMPQ3906 currently available?

A: Yes. The onsemi MMPQ3906 carries Active product status with 3224 pieces in stock, ensuring reliable procurement compared to the obsolete Central Semiconductor part.
