Product details

Overview

30A02CH-TL-E from onsemi is a PNP bipolar junction transistor rated for −30 V V_CEO, −700 mA continuous collector current, and featuring low V_CE(sat) of −110 mV (typ.) at I_C = −200 mA / I_B = −10 mA. It uses CPH3 surface-mount package and serves as a high-speed switching device in low-frequency amplifier and small motor drive circuits.

For engineers reviewing the 30A02CH-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include verified V_CE(sat), h_FE range (200–500), f_T = 520 MHz, thermal derating per ambient temperature, and CPH3 mechanical compatibility with 0.8 mm ceramic board mounting.

Technical Context

This PNP BJT operates with fixed-base driven saturation switching and exhibits strong current gain linearity across I_C = −10 mA to −700 mA at V_CE = −2 V. Its low output capacitance (C_ob = 4.7 pF at V_CB = −10 V) and fast switching times (t_on = 35 ns, t_f = 25 ns) support stable performance in pulse-width modulated motor control stages.

The device is characterized for operation up to T_j = 150°C and requires thermal management via mounting on a 600 mm² × 0.8 mm ceramic board to sustain 700 mW power dissipation. Absolute maximum ratings are strictly defined for V_CBO, V_CEO, and V_EBO with no derating applied below T_a = 25°C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−30 V - Maximum allowable collector-to-emitter voltage before breakdown under open-base condition
I_C (continuous)	−700 mA - Continuous collector current rating defining safe DC conduction capability
V_CE(sat)	−110 mV (typ.) at I_C = −200 mA / I_B = −10 mA - Low saturation voltage enables minimal power loss in switching mode
h_FE	200–500 at V_CE = −2 V, I_C = −10 mA - Confirmed DC current gain range for reliable base drive design
f_T	520 MHz - Gain-bandwidth product indicating usable frequency limit for small-signal amplification
C_ob	4.7 pF at V_CB = −10 V, f = 1 MHz - Output capacitance affecting high-speed switching edge integrity
t_on/t_f	35 ns / 25 ns - Verified turn-on and fall times supporting ≥10 MHz digital switching applications

Pinout & Package

30A02CH-TL-E is housed in the CPH3 package (Case 318BA), a 3-pin surface-mount plastic package with gull-wing leads optimized for automated assembly and thermal conduction to ceramic PCB substrates.

Key Features

High f_T	520 MHz - Enables stable amplification up to UHF band without external compensation
Controlled h_FE spread	200–500 - Supports predictable base resistor selection across production lots
Low C_ob	4.7 pF - Minimizes Miller effect during fast transitions, preserving switching speed

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP switching transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT3906LT1G	V_CEO = −40 V, I_C = −200 mA, V_CE(sat) = −300 mV (typ.) at I_C = −10 mA	Lower current rating and higher saturation voltage limit use in <200 mA loads only	Select when higher V_CEO margin is required and thermal constraints allow larger V_CE(sat) loss

FAQ

What is the maximum continuous collector current rating for the 30A02CH-TL-E?

The 30A02CH-TL-E has a maximum continuous collector current (I_C) rating of −700 mA at T_a = 25°C when mounted on a 600 mm² × 0.8 mm ceramic board. Derating applies above 25°C ambient, with full power dissipation (700 mW) sustained up to ~80°C ambient per Figure 11 in the official datasheet. This rating ensures reliable operation in motor drive and switching applications without forced cooling.

Does the 30A02CH-TL-E support high-speed switching in PWM circuits?

Yes, the 30A02CH-TL-E supports high-speed switching with verified t_on = 35 ns and t_f = 25 ns under standard test conditions (V_CC = −12 V, I_C = −300 mA). Its 520 MHz f_T and low C_ob = 4.7 pF enable clean edge transitions up to 10–20 MHz, making it suitable for PWM motor control and digital load switching where timing fidelity is critical.

What is the package type and lead finish of the 30A02CH-TL-E?

The 30A02CH-TL-E uses the CPH3 package (Case 318BA), a 3-pin surface-mount plastic package with gull-wing leads. It is Pb-free and RoHS-compliant, with matte tin (Sn) lead finish. The package is optimized for reflow soldering and thermal conduction to ceramic PCB substrates, supporting the specified 700 mW power dissipation rating.

How does the V_CE(sat) of the 30A02CH-TL-E compare to standard PNP transistors?

The 30A02CH-TL-E achieves V_CE(sat) = −110 mV (typ.) at I_C = −200 mA / I_B = −10 mA-significantly lower than standard PNP transistors like the MMBT3906 (−300 mV typ.). This 63% reduction in saturation voltage directly lowers conduction losses, improves efficiency in battery-powered systems, and reduces thermal stress in densely packed PCB layouts.

Is the 30A02CH-TL-E suitable for automotive-grade applications?

The 30A02CH-TL-E is not AEC-Q101 qualified and is not recommended for automotive safety-critical systems. However, its 150°C junction rating, −30 V breakdown voltage, and robust thermal behavior make it suitable for non-safety automotive subsystems such as cabin HVAC actuators, mirror controls, and interior lighting drivers-provided full system-level qualification is performed by the end customer.
