onsemi 30C02MH-TL-H

Overview

30C02MH-TL-H from onsemi is a low-V_CE(sat) NPN bipolar transistor in MCPH3 (SC-70/SOT-323) package, rated for 30V V_CEO, 700mA I_C, and 330mΩ typical R_CE(sat) at I_C=0.7A/ I_B=35mA. It delivers high-speed switching and low-loss amplification in space-constrained motor drive and signal interface circuits.

For engineers reviewing the 30C02MH-TL-H datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat) ≤190mV at 200mA/10mA drive, f_T = 540MHz gain-bandwidth, h_FE range of 300–800 at 50mA, Cob = 3.3pF, and halogen-free Pb-free compliance per ordering suffix -H.

Technical Context

This device operates as a single NPN switch/amplifier with junction temperature up to 150°C and storage range from –55°C to +150°C. Its low saturation resistance enables efficient current handling in DC-coupled small-motor drivers and logic-level interface stages where thermal dissipation on ceramic substrates is constrained to 600mW.

Switching performance is characterized by t_on = 35ns, t_stg = 255ns, and t_f = 40ns under specified test conditions (V_CC = 12V, I_C = 300mA, P_W = 20μs). The f_T–I_C curve confirms usable RF gain up to ~100MHz at I_C = 10mA, supporting broadband low-noise preamplifier use cases.

FAQ

What is the maximum continuous collector current rating for the 30C02MH-TL-H?

The 30C02MH-TL-H is rated for 700mA continuous collector current (I_C) at T_a = 25°C when mounted on a ceramic substrate (600 mm² × 0.8 mm). Derating applies above 25°C ambient; at 75°C, maximum I_C drops to approximately 450mA per the PC–Ta curve. This rating ensures reliable operation in motor driver and power switch applications without forced airflow.

Does the 30C02MH-TL-H have halogen-free and lead-free compliance?

Yes, the 30C02MH-TL-H is both halogen-free and lead-free, as indicated by the "-H" suffix in its part number. It meets JESD201A Class 1A for halogen content and complies with RoHS Directive 2011/65/EU. This makes the 30C02MH-TL-H suitable for environmentally regulated markets including EU industrial equipment and medical devices requiring green material declarations.

What is the typical V_CE(sat) of the 30C02MH-TL-H under standard switching conditions?

The typical V_CE(sat) of the 30C02MH-TL-H is 130mV at I_C = 200mA and I_B = 10mA, with a guaranteed max of 190mV under those conditions. At full-rated I_C = 700mA and I_B = 35mA, R_CE(sat) is typically 330mΩ - translating to ~230mV saturation voltage - enabling low-loss operation in high-current switching circuits.

Can the 30C02MH-TL-H be used in RF amplifier designs?

Yes, the 30C02MH-TL-H has a gain-bandwidth product (f_T) of 540MHz and low output capacitance (C_ob = 3.3pF), supporting stable small-signal amplification up to ~100MHz. Its h_FE remains >150 at 100MHz, making the 30C02MH-TL-H viable for VHF preamplifiers, RF detector biasing, and broadband buffer stages where moderate gain and low noise are required.

What is the pin configuration and package type of the 30C02MH-TL-H?

The 30C02MH-TL-H uses the MCPH3 package (JEITA: SC-70, JEDEC: SOT-323), with pin 1 = Base, pin 2 = Emitter, pin 3 = Collector. Its dimensions are 2.1 × 1.6 × 0.85 mm, and it features gull-wing leads on 0.65 mm pitch. This standardized footprint allows drop-in replacement with other SC-70 NPN transistors while maintaining mechanical compatibility with high-speed pick-and-place equipment.
