Product details

Overview

MCH6124-TL-E from onsemi is a PNP bipolar junction transistor in MCPH6 package, rated for −20 V V_CEO, −3 A I_C, and −195 mV V_CE(sat) at −1.5 A/−75 mA drive, optimized for high-efficiency load switching in compact DC-DC converters and motor drivers.

For engineers reviewing the MCH6124-TL-E datasheet, pinout, applications, or equivalent options, key selection criteria include verified low saturation voltage, guaranteed IECO reverse-flow blocking, 400 MHz f_T, and ultrasmall 2.1 × 1.6 × 0.85 mm package with four collector terminals.

Technical Context

This PNP transistor employs onsemi's MBIT process to achieve high current gain (h_FE = 200–560 at −100 mA) and fast switching (t_on = 35 ns, t_f = 12 ns), enabling efficient operation in pulse-driven load control circuits.

Its dual-collector configuration (pins 1,2,5,6) supports parallel current handling and thermal spreading, while the guaranteed IECO parameter ensures reliable emitter-to-collector reverse leakage suppression under bias reversal conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−20 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration
I_C	−3 A - Continuous DC collector current rating at T_a = 25°C with ceramic substrate mounting
V_CE(sat)	−130 to −195 mV - Confirmed saturation voltage range at −1.5 A/−75 mA, directly enabling <0.3 W conduction loss
f_T	400 MHz - Gain-bandwidth product ensuring stable high-speed switching up to ~100 MHz practical operation
IECO	−1 μA max at V_EC = −4.5 V - Guaranteed reverse emitter-collector leakage, critical for bidirectional blocking in charger FETs
P_C	1 W - Maximum power dissipation when mounted on 600 mm² × 0.8 mm ceramic substrate
h_FE	200–560 - DC current gain range at V_CE = −2 V, I_C = −100 mA, supporting robust base drive design margin

Pinout & Package

Package: MCPH6 (JEITA SC-88 / JEDEC SC-70-6 / SOT-363), ultrasmall outline measuring 2.1 mm × 1.6 mm × 0.85 mm height, with exposed thermal pad not electrically connected.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6	Collector	Four independent collector terminals - enable parallel connection for higher current handling and improved thermal distribution
3	Base	Single base input - controls conduction state; requires −75 mA for full saturation at −1.5 A I_C
4	Emitter	Common emitter node - serves as reference terminal and primary current return path in PNP topology

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
NSV6124MUTBG	Same MCPH6 package, identical V_CEO/I_C, but V_CE(sat) = −220 mV (max) at same bias - 13% higher conduction loss	Lacks guaranteed IECO specification - requires external diode for reverse-blocking in charger designs	Select when cost sensitivity outweighs 0.03 W loss penalty and reverse-blocking is handled elsewhere

FAQ

What is the maximum continuous collector current for the MCH6124-TL-E?

The MCH6124-TL-E supports −3 A continuous collector current (I_C) at T_a = 25°C when mounted on a 600 mm² × 0.8 mm ceramic substrate. Derating applies above 25°C ambient; at 75°C, the usable I_C drops to approximately −2.1 A per the PC–Ta curve. This rating is validated under specified thermal conditions and must be applied with appropriate board-level heatsinking for sustained operation.

Does the MCH6124-TL-E have a guaranteed reverse leakage specification?

Yes, the MCH6124-TL-E specifies IECO ≤ −1 μA at V_EC = −4.5 V, IB = 0 A - a guaranteed parameter that ensures minimal reverse current flow from emitter to collector. This makes the MCH6124-TL-E suitable for applications like battery chargers where reverse-current blocking is essential without adding external diodes.

What is the pin configuration of the MCH6124-TL-E in the MCPH6 package?

The MCH6124-TL-E uses a 6-pin MCPH6 package with pins 1, 2, 5, and 6 all connected to the collector, pin 3 as the base, and pin 4 as the emitter. This four-collector layout improves current sharing and thermal performance. The marking "BA" appears on the top surface, and the device is supplied in Pb-free TL (tape-and-reel) format with 3,000 units per reel.

How does the MCH6124-TL-E compare to standard PNP transistors in switching speed?

The MCH6124-TL-E achieves t_on = 35 ns and t_f = 12 ns under defined test conditions, enabled by its 400 MHz f_T and MBIT process. This is 2–3× faster than typical general-purpose PNP transistors (e.g., BC807 series), allowing reliable operation at PWM frequencies up to 5 MHz with reduced switching losses and tighter timing control in the MCH6124-TL-E.

Is the MCH6124-TL-E suitable for use in hot-swap controllers?

Yes, the MCH6124-TL-E is suitable for hot-swap controller applications due to its −3 A continuous rating, 1 W power dissipation capability on ceramic substrate, and fast 12 ns fall time. Its guaranteed IECO and low V_CE(sat) support precise inrush limiting and fault isolation. Designers must ensure gate/base drive circuitry provides adequate current (−75 mA) and thermal management aligns with the MCH6124-TL-E's 150°C T_j limit.
