Product details
Overview
30C02SP-AC from ON Semiconductor is a low-VCE(sat) NPN bipolar transistor in MCPH3 (SC-70/SOT-323) package, rated for 30 V VCEO, 700 mA IC, and 330 mΩ typical RCE(sat) at IC = 0.7 A / IB = 35 mA. It delivers high-current switching performance with ultrasmall footprint, suited for compact motor drive and low-frequency amplifier stages in space-constrained industrial controls.
For engineers reviewing the 30C02SP-AC datasheet, pinout, applications, or equivalent options, key selection criteria include verified VCE(sat) ≤ 190 mV at IC = 200 mA / IB = 10 mA, fT = 540 MHz gain-bandwidth, hFE range of 300–800 at IC = 50 mA, and halogen-free compliance per JEDEC/JEITA SC-70 standards.
Technical Context
This device operates as a single NPN switching transistor optimized for low-saturation-loss operation in DC-to-low-MHz signal paths. Its design emphasizes fast turn-on (ton = 35 ns) and controlled storage time (tstg = 255 ns), enabling reliable pulse-width modulation in small motor drivers and relay interface circuits.
The MCPH3 package provides thermal resistance suitable for 600 mW dissipation on ceramic substrate (600 mm² × 0.8 mm), with validated junction temperature limit of 150°C and storage range from –55°C to +150°C - supporting extended reliability in industrial ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 30 V - maximum collector-emitter voltage before breakdown under open-base condition; defines safe DC rail margin for 24 V systems. |
| IC | 700 mA - continuous collector current rating; supports driving loads up to ~150 mW at VCE = 2 V with stable hFE. |
| VCE(sat) | 85–190 mV @ IC=200 mA, IB=10 mA - enables <150 mW conduction loss in switching mode; critical for thermal management in sealed enclosures. |
| fT | 540 MHz - usable bandwidth for low-noise pre-amplifier stages or high-speed digital switching up to ~50 MHz square waves. |
| hFE | 300–800 @ VCE=2 V, IC=50 mA - ensures robust base drive margin across production lots and temperature extremes (–25°C to +75°C). |
| Cob | 3.3 pF @ VCB=10 V, f=1 MHz - minimizes Miller effect in high-gain configurations; supports clean edge integrity in 20 μs pulse applications. |
Pinout & Package
MCPH3 (JEITA/IEC SC-70, JEDEC SOT-323) is a 3-pin ultrasmall surface-mount package measuring 2.1 × 1.6 × 0.85 mm, with 0.65 mm lead pitch and 0.007 g mass. Designed for automated placement and reflow compatibility on standard PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input node requiring ≥10 mA base drive for full saturation; connected via current-limiting resistor in switch-mode bias networks. |
| 2 | Emitter | Common reference terminal tied to system ground or low-side return path; carries full load current and must be routed with low-inductance copper. |
| 3 | Collector | High-side output node delivering switched load current; requires thermal pad connection or adjacent copper pour for 600 mW dissipation capability. |
Key Features
| Feature | Design Value |
|---|---|
| Low VCE(sat) | Typical 190 mV at IC = 200 mA enables <0.04 W conduction loss - reduces heatsinking needs in fanless industrial modules. |
| Ultrasmall footprint | MCPH3 package occupies <3.4 mm² PCB area - allows integration into wearables, sensor nodes, and multi-channel driver IC footprints. |
| High fT | 540 MHz bandwidth supports stable amplification up to 50 MHz with minimal phase shift - suitable for RF detector front-ends and clock buffer stages. |
| Halogen-free construction | Complies with IEC 61249-2-21 and JEDEC J-STD-020; eliminates brominated flame retardants without compromising moisture sensitivity level (MSL3). |
Applications
| Low-Frequency Amplifier | High-Speed Switching |
|---|---|
Use Scenario: Audio preamplifier stage in battery-powered instrumentation with 2–20 kHz signal band. IC Role / Device Role / Timing Role: NPN common-emitter amplifier providing 20 dB voltage gain with <1% THD at 1 VPP output. Use Value: hFE stability over –25°C to +75°C ensures consistent gain calibration across operating temperature range. | Use Scenario: PWM-controlled solenoid driver in HVAC actuator with 20 μs pulse width and 1 kHz repetition rate. IC Role / Device Role / Timing Role: Low-loss saturated switch turning 300 mA load on/off with ton/tf < 75 ns total transition time. Use Value: VCE(sat) ≤ 190 mV limits power dissipation to <60 mW during active state - avoids derating at 75°C ambient. |
| Small Motor Drive | Relay Interface Circuit |
Use Scenario: Bidirectional brushed DC motor control in portable medical pumps (12 V supply, 500 mA stall current). IC Role / Device Role / Timing Role: Low-side switch in H-bridge half-bridge configuration handling peak 700 mA pulsed current. Use Value: RCE(sat) typ = 330 mΩ ensures <120 mW worst-case conduction loss at full load - compatible with 600 mW ceramic-substrate thermal budget. | Use Scenario: Optocoupler-isolated relay driver in PLC I/O module with 24 V DC coil and 10 ms turn-on requirement. IC Role / Device Role / Timing Role: Final-stage current amplifier delivering 30 mA base drive to relay transistor with <100 ns propagation delay. Use Value: Fast storage time (tstg = 255 ns) prevents relay chatter during rapid on/off cycling - validated at 10 Hz switching. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT3904LT1G | VCEO = 40 V, IC = 200 mA, VCE(sat) = 300 mV @ IC = 50 mA - lower current capacity and higher saturation voltage. | Not suitable for 700 mA motor drive; limited to signal-level switching and low-power logic interfacing. | Select when only 200 mA load current and 40 V breakdown are required; cost-optimized for non-power applications. |
| DXT75500Q-7 | VCEO = 30 V, IC = 1.5 A, VCE(sat) = 120 mV @ IC = 1 A - higher current rating and lower saturation voltage in SOT-563 package. | Requires larger PCB footprint (2.9 × 1.6 mm) and different layout; supports higher thermal loads but not drop-in replacement. | Select when >700 mA peak current or <120 mV VCE(sat) is mandatory; verify thermal pad routing and assembly process compatibility. |
Compared with MMBT3904LT1G and DXT75500Q-7, the 30C02SP-AC uniquely balances 700 mA current handling, sub-200 mV saturation, and SC-70 miniaturization - making it optimal for space-constrained industrial actuators where both power efficiency and board area are constrained.

FAQ
What is the maximum continuous collector current rating for the 30C02SP-AC?
The 30C02SP-AC is rated for 700 mA continuous collector current (IC) at Ta = 25°C when mounted on a ceramic substrate (600 mm² × 0.8 mm). Derating applies above 25°C ambient, with full-rated current maintained up to ~60°C under typical PCB copper pour conditions. This rating is confirmed in the Absolute Maximum Ratings table of the official ON Semiconductor datasheet for 30C02SP-AC.
Does the 30C02SP-AC have halogen-free and lead-free compliance?
Yes, the 30C02SP-AC meets halogen-free requirements per IEC 61249-2-21 and is Pb-free per JEDEC J-STD-020. The "-H" suffix variant (e.g., 30C02MH-TL-H) explicitly denotes halogen-free construction, and the 30C02SP-AC shares identical material specifications and qualification testing per ON Semiconductor's product change notices and packaging documentation.
What is the typical VCE(sat) of the 30C02SP-AC under standard switching conditions?
The typical collector-to-emitter saturation voltage (VCE(sat)) for the 30C02SP-AC is 190 mV at IC = 200 mA and IB = 10 mA, with a maximum of 190 mV guaranteed across production lots. This value is measured per the Electrical Characteristics table in the ON Semiconductor datasheet and reflects stable low-loss operation ideal for thermally sensitive designs.
Can the 30C02SP-AC be used in linear amplifier configurations?
Yes, the 30C02SP-AC supports linear operation with DC current gain (hFE) ranging from 300 to 800 at VCE = 2 V and IC = 50 mA. Its fT of 540 MHz and low Cob (3.3 pF) enable stable mid-band amplification up to ~50 MHz, provided thermal limits (Tj ≤ 150°C) and SOA constraints are observed in bias design.
What package type does the 30C02SP-AC use, and what are its key mechanical dimensions?
The 30C02SP-AC uses the MCPH3 package, equivalent to JEDEC SOT-323 and JEITA SC-70. Its dimensions are 2.1 mm × 1.6 mm × 0.85 mm with 0.65 mm lead pitch and 0.007 g mass.
