onsemi TIP30G

Overview

TIP30G from onsemi is a PNP silicon power transistor in TO−220 package, rated for 40 V_CEO, 1.0 A continuous collector current, and 30 W total power dissipation at T_C = 25°C. It serves as a general-purpose amplifier and switching device in DC power supplies, motor drivers, and relay interface circuits.

For engineers reviewing the TIP30G datasheet, pinout, applications, or equivalent options, key selection criteria include its complementary pairing with TIP29G, guaranteed V_CEO = 40 V, h_FE ≥ 40 at I_C = 0.2 A, V_CE(sat) ≤ 0.7 V, and Pb-free TO−220 thermal performance (R_JC = 4.167 °C/W).

Technical Context

The TIP30G operates as a medium-power PNP bipolar junction transistor optimized for linear amplification and hard-switching applications. Its design supports DC bias stability with V_EB = 5.0 V maximum and I_EBO ≤ 1.0 mA, while sustaining unclamped inductive load energy of 32 mJ under defined test conditions (L_C = 20 mH, V_CC = 10 V).

Thermal management is enabled by low junction-to-case resistance (4.167 °C/W) and operation across –65°C to +150°C junction temperature range. Electrical behavior is characterized at T_C = 25°C, with f_T = 3.0 MHz and h_fe = 20 at 1 kHz, confirming suitability for audio-frequency amplification and moderate-speed switching.

FAQ

What is the pin configuration of the TIP30G?

The TIP30G uses TO−220 package with pinout: Pin 1 = Base, Pins 2 & 4 = Collector (tied to metal tab), Pin 3 = Emitter. This B-C-E arrangement is standard for PNP devices in this family and matches the mechanical layout shown in Figure 5 of the official datasheet. Always verify orientation using the marking diagram: "TIP30G" printed on the front face with tab facing up and leads down.

Is the TIP30G RoHS compliant?

Yes, the TIP30G is explicitly marked with the "G" suffix indicating Pb-free and RoHS-compliant construction per EU Directive 2011/65/EU. The datasheet confirms compliance in the Features section and references the ON Semiconductor Soldering and Mounting Techniques Reference Manual for lead-free process guidelines. No exemptions apply.

How does the TIP30G differ from the TIP30CG?

The TIP30G has V_CEO = 40 V, while the TIP30CG is rated for 100 V. All other parameters-including I_C = 1.0 A, P_D = 30 W, h_FE range, and TO−220 package-are identical. The "G" suffix denotes Pb-free packaging for both; the letter "C" indicates the higher-voltage variant. They are not interchangeable without verifying circuit voltage stress margins.

Can the TIP30G be used as a direct replacement for the TIP30?

Yes, the TIP30G replaces the legacy TIP30 with identical electrical specifications and TO−220 mechanical form factor, differing only in Pb-free packaging. The "G" suffix confirms RoHS compliance without performance trade-offs. No PCB or schematic changes are needed-only ensure soldering profile aligns with Pb-free requirements per ON Semiconductor's SOLDERRM/D manual.

What is the maximum safe operating temperature for the TIP30G junction?

The TIP30G has a specified operating and storage junction temperature range of –65°C to +150°C. For reliable long-term operation, sustained junction temperature should remain ≤ +150°C. Derating curves show that at T_C = 100°C, maximum allowable P_D drops to approximately 12 W. Thermal design must account for R_JC = 4.167 °C/W and system-level R_CA.
