Product details

Overview

30A02MH-TL-H from onsemi is a PNP bipolar junction transistor rated for −30 V V_CEO, −700 mA I_C, and 600 mW power dissipation on ceramic substrate, featuring low V_CE(sat) of −220 mV at I_C = −200 mA/I_B = −10 mA, f_T = 520 MHz, and h_FE up to 500 - used in low-frequency amplification and high-speed switching for small motor drive circuits.

For engineers reviewing the 30A02MH-TL-H datasheet, pinout, applications, or equivalent options, key selection factors include verified V_CE(sat) performance at −200 mA, guaranteed h_FE range (200–500), R_CE(sat) ≈ 580 mΩ, switching times (t_on = 35 ns, t_f = 25 ns), and Pb-free + halogen-free compliance per TL-H packing.

Technical Context

This PNP BJT operates with emitter-grounded configuration and supports DC amplification and active-mode switching. Its gain-bandwidth product of 520 MHz enables stable operation up to low RF frequencies, while low saturation voltage ensures minimal conduction loss in driver stages.

The device uses a single-die MCPH3 package with SC-70/SOT-323 footprint compatibility, thermally optimized for ceramic substrates (600 mm² × 0.8 mm). Absolute maximum ratings are strictly defined: V_CBO = V_CEO = −30 V, V_EBO = −5 V, T_j = 150 °C, and I_C = −700 mA continuous.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−30 V - maximum allowable collector-to-emitter voltage before breakdown in common-emitter configuration
I_C	−700 mA - continuous collector current rating defining safe linear/switching load capacity
V_CE(sat)	−220 mV typ at I_C = −200 mA/I_B = −10 mA - low conduction loss enabling efficient switching in low-voltage driver circuits
f_T	520 MHz - usable bandwidth limit for small-signal amplification or RF-coupled switching applications
h_FE	200–500 at V_CE = −2 V/I_C = −10 mA - predictable DC current gain supporting stable bias design
t_f	25 ns - fast fall time enabling ≤40 MHz square-wave switching without significant distortion
P_C	600 mW on ceramic substrate (600 mm² × 0.8 mm) - thermal derating boundary for PCB layout planning

Pinout & Package

MCPH3 is a surface-mount, 3-pin plastic package conforming to JEITA SC-70 and JEDEC SOT-323 standards, with 0.65 mm lead pitch, 2.1 mm × 1.6 mm body size, and 0.007 g mass. It supports reflow soldering and is qualified for automated assembly.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control terminal for forward-biased PNP operation; requires negative base current relative to emitter to turn on
2	Emitter	Common reference node in CE configuration; connected to higher potential rail in typical switching layouts
3	Collector	Output current path; sinks current when device is ON, with voltage drop governed by V_CE(sat)

Key Features

Feature	Design Value
Low V_CE(sat)	−220 mV typ at I_C = −200 mA - reduces power loss and self-heating in high-duty-cycle switching
High f_T	520 MHz - supports clean signal amplification and fast edge transitions in digital interface drivers
Guaranteed h_FE range	200–500 - enables robust bias network design without gain-dependent instability
Halogen-free & Pb-free	TL-H packing - meets IEC 61249-2-21 and RoHS Directive requirements for green manufacturing
Fast switching	t_on = 35 ns, t_f = 25 ns - minimizes transition losses in PWM-controlled loads like small DC motors

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT3906LT1G	V_CEO = −40 V, I_C = −200 mA, V_CE(sat) = −300 mV @ I_C = −10 mA - higher voltage rating but lower current and higher saturation voltage	More suitable for general-purpose logic-level switching where current < 200 mA and voltage > 30 V required	Select when higher V_CEO margin is critical and load current remains below 200 mA
DXT3906-7-F	V_CEO = −40 V, I_C = −2 A (pulse), V_CE(sat) = −250 mV @ I_C = −500 mA - higher pulse current capability but larger SOT-563 package	Better suited for intermittent high-current loads (e.g., relay coils) requiring >700 mA peak	Choose when board space permits larger footprint and pulse current exceeds 700 mA

Compared with MMBT3906LT1G and DXT3906-7-F, the 30A02MH-TL-H delivers optimal balance of −700 mA continuous current, −220 mV V_CE(sat), and compact MCPH3 packaging - making it preferred for space-constrained, medium-current switching where thermal efficiency matters.

What is the maximum continuous collector current rating for the 30A02MH-TL-H?

The 30A02MH-TL-H has a maximum continuous collector current (I_C) rating of −700 mA at T_a = 25 °C when mounted on a ceramic substrate (600 mm² × 0.8 mm). Derating applies above 25 °C ambient, with full derating to zero at 150 °C junction temperature. This rating is confirmed in the Absolute Maximum Ratings table of the official onsemi datasheet No. 7359.

Does the 30A02MH-TL-H support Pb-free and halogen-free compliance?

Yes, the 30A02MH-TL-H is explicitly marked as Pb-free and halogen-free per its TL-H packing designation. This complies with RoHS Directive 2011/65/EU and IEC 61249-2-21, and is documented in the Ordering Information section of the onsemi datasheet No. 7359. The TL-E variant is Pb-free only.

What is the typical V_CE(sat) of the 30A02MH-TL-H under standard switching conditions?

The typical collector-to-emitter saturation voltage (V_CE(sat)) of the 30A02MH-TL-H is −220 mV at I_C = −200 mA and I_B = −10 mA, as specified in the Electrical Characteristics table (Ta = 25 °C). This value reflects low conduction loss essential for efficient switching in motor and LED driver applications.

Is the 30A02MH-TL-H pin-compatible with standard SOT-323 footprints?

Yes, the 30A02MH-TL-H uses the MCPH3 package, which conforms to both JEITA SC-70 and JEDEC SOT-323 mechanical standards. Its 0.65 mm lead pitch, 2.1 mm × 1.6 mm body, and pin 1–2–3 assignment (Base–Emitter–Collector) match industry-standard SOT-323 land patterns, enabling direct use in existing SOT-323 layouts.

What is the guaranteed h_FE range for the 30A02MH-TL-H at V_CE = −2 V and I_C = −10 mA?

The 30A02MH-TL-H guarantees a DC current gain (h_FE) range of 200 to 500 under test conditions of V_CE = −2 V and I_C = −10 mA at T_a = 25 °C.
