TIP30 Equivalent & Substitute Parts

Part Overview

The TIP30 is a Bipolar (BJT) Transistor with PNP polarity, rated for 40 V collector-emitter breakdown voltage and 1 A maximum collector current. Manufactured by onsemi, this component is packaged in a Through Hole TO-220-3 configuration and is designed for general-purpose switching and amplification applications with a maximum power dissipation of 2 W.

The TIP30 is classified as Obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications currently utilizing this component.

Substitute Part Grouping Explanation

Substitution of the TIP30 is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

Transistor Type: PNP polarity must be maintained
Current - Collector (Ic) (Max): Substitute must support minimum 1 A
Vce Saturation: Must not exceed 700mV @ 125mA, 1A
Current - Collector Cutoff (Max): Must not exceed 300µA
DC Current Gain (hFE) (Min): Must meet or exceed 15 @ 1A, 4V
Power - Max: Must support minimum 2 W dissipation
Frequency - Transition: Must support minimum 3MHz
Operating Temperature: Must cover -65°C ~ 150°C range
Mounting Type: Through Hole configuration required
Package / Case: TO-220-3 form factor required

Voltage Rating Consideration: The TIP30 is rated for 40 V maximum collector-emitter breakdown voltage. Substitute parts may exceed this voltage rating while maintaining all other electrical specifications, as higher voltage ratings provide design margin without compromising performance in 40 V applications.

Engineering Selection Recommendations

The TIP30CG is a direct functional substitute for the TIP30 across all critical electrical parameters. Both components share identical collector current, saturation voltage, cutoff current, DC current gain, power dissipation, transition frequency, and operating temperature range. Both utilize the same Through Hole TO-220-3 package configuration, ensuring mechanical and thermal compatibility.

The TIP30CG provides an enhanced voltage rating of 100 V compared to the TIP30's 40 V specification. This higher voltage rating does not compromise performance in applications designed for 40 V operation and provides additional design margin.

The TIP30CG holds Active product status, ensuring ongoing availability and supply chain support. The TIP30CG is ROHS3 Compliant, meeting current environmental and regulatory requirements, whereas the TIP30 is RoHS non-compliant. For new designs or production requiring regulatory compliance, the TIP30CG is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the TIP30CG directly replace the TIP30 in existing designs?

A: Yes. The TIP30CG maintains identical electrical specifications for collector current (1 A), saturation voltage (700mV @ 125mA, 1A), cutoff current (300µA), DC current gain (15 @ 1A, 4V), power dissipation (2 W), transition frequency (3MHz), and operating temperature range (-65°C ~ 150°C). The TO-220-3 package configuration is identical, enabling direct pin-compatible substitution.

Q: What is the significance of the higher voltage rating on the TIP30CG?

A: The TIP30CG is rated for 100 V collector-emitter breakdown voltage, compared to the TIP30's 40 V rating. In applications operating at or below 40 V, this higher rating provides additional design margin and protection against voltage transients without altering circuit performance.

Q: Are there packaging differences between the TIP30 and TIP30CG?

A: Both components utilize the Through Hole TO-220-3 package configuration. The TIP30CG is supplied in Tube packaging, while the TIP30 packaging specification was not provided. The functional package form factor remains identical for PCB mounting and thermal management purposes.

Q: Why is the TIP30 classified as Obsolete?

A: The TIP30 is no longer in active production. The TIP30CG, manufactured by the same supplier (onsemi), provides equivalent electrical performance with Active product status and current regulatory compliance (ROHS3).

Q: What compliance considerations apply to substitution?

A: The TIP30 is RoHS non-compliant. The TIP30CG is ROHS3 Compliant. For applications subject to environmental regulations or customer requirements mandating RoHS compliance, the TIP30CG is the required selection.
