Product details
Overview
MJH11019 from onsemi is a PNP complementary Darlington silicon power transistor designed for high-voltage, medium-power linear amplification and low-frequency switching in motor control and industrial power stages. It delivers 200 Vdc collector-emitter sustaining voltage (VCEO(sus)), 15 A continuous collector current, and 150 W total device dissipation at TC = 25°C - enabling robust operation in DC motor drives and relay drivers.
For engineers reviewing the MJH11019 datasheet, pinout, applications, or equivalent options, key selection criteria include its 200 V sustain rating, Darlington hFE ≥ 400 at 10 Adc, TO-247/TO-218 package thermal resistance (RJC = 0.83°C/W), and verified reverse-bias safe operating area (RBSOA) for inductive turn-off.
Technical Context
The MJH11019 integrates two monolithic PNP transistors in Darlington configuration to achieve high DC current gain while maintaining rugged high-voltage capability. Its VCEO(sus) = 200 Vdc and VCB = 200 Vdc ratings are validated under pulse conditions (300 µs, 2% duty cycle), supporting reliable operation in clamped inductive switching.
Thermal performance is defined by RJC = 0.83°C/W and a junction temperature range of –65°C to +150°C. Dynamic behavior includes fT = 3.0 MHz (IC = 10 A, VCE = 3.0 V, f = 1 MHz) and Cob = 400–600 pF (VCB = 10 Vdc, IE = 0, f = 0.1 MHz), confirming suitability for <100 kHz power control applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO(sus) | 200 Vdc minimum - supports 160 VDC bus designs with 25% safety margin against transient overvoltage |
| IC (continuous) | 15 Adc - enables direct drive of 1–2 HP DC motors or high-current solenoid loads without external current boosting |
| hFE (DC gain) | ≥400 @ IC = 10 Adc, VCE = 5.0 Vdc - reduces required base drive current to ≤25 mA for full conduction |
| VCE(sat) | 2.5 V typical @ IC = 10 Adc, IB = 100 mA - limits conduction loss to ≤25 W at rated current, easing heatsink requirements |
| RJC | 0.83°C/W - allows 150 W dissipation with ≤125°C case-to-ambient delta, compatible with standard finned aluminum heatsinks |
| Cob | 400–600 pF @ VCB = 10 Vdc - ensures predictable turn-off timing in <50 kHz PWM circuits without excessive Miller effect |
| fT | 3.0 MHz - confirms usable small-signal bandwidth for feedback compensation in linear amplifier configurations |
Pinout & Package
Package: TO-247 (Case 340L, Style 3) or TO-218 (Case 340D, Style 1), both Pb-free, with isolated collector tab for direct heatsink mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Low-impedance input controlling Darlington pair; requires current-limited drive (IB ≤ 0.5 Adc) to avoid second breakdown |
| 2 | Collector | Main high-current, high-voltage output terminal; electrically connected to metal tab for thermal and electrical grounding |
| 3 | Emiter | Power return path; referenced to system ground in common-emitter configurations; not internally tied to base |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic Darlington construction | Eliminates inter-device parameter mismatch and thermal drift between driver and output transistors |
| 200 V VCEO(sus) rating | Enables use in 120/240 VAC rectified bus applications without series stacking or snubber networks |
| 150 W PD @ TC = 25°C | Supports sustained 10 A output into resistive loads with standard forced-air heatsinking (ΔT ≤ 60°C) |
| RBSOA compliance | Validated up to 100 V / 10 A under clamped inductive turn-off (TC = 100°C, 10% duty cycle), preventing secondary breakdown |
| Pb-free packaging | Meets RoHS Directive 2011/65/EU and JEDEC J-STD-020 reflow profile requirements for lead-free assembly |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP Darlington power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MJH11021 | Higher VCEO(sus) = 250 Vdc, same package and pinout; higher Cob (600 pF vs. 400–600 pF) | Better suited for 220 VAC rectified inputs; slightly slower switching due to increased capacitance | Select MJH11021 only when >200 V sustain is required; otherwise MJH11019 offers optimal balance of voltage, speed, and thermal performance. |
| BDW10 | Lower VCEO(sus) = 100 Vdc, TO-3 package, RJC ≈ 1.5°C/W, hFE ≥ 750 but lower power rating (100 W) | Limited to ≤80 VDC systems; requires larger heatsink for equivalent current handling | BDW10 is viable only in legacy 100 V designs with space for TO-3 mounting; MJH11019 provides 2× power density and 2× voltage margin in TO-247. |
Compared with MJH11021 and BDW10, the MJH11019 uniquely delivers 200 V sustain in a thermally efficient TO-247 package with verified RBSOA - making it the preferred choice for new 120–180 VDC industrial motor and power supply designs where reliability under inductive stress is critical.

FAQ
What is the maximum continuous collector current rating for the MJH11019?
The MJH11019 has a maximum continuous collector current (IC) rating of 15 Adc at TC = 25°C. Derating applies above 25°C at 1.2 W/°C, and peak current is rated at 30 Adc under pulsed conditions (5 ms, 10% duty cycle). This rating is confirmed in the "Maximum Ratings" table of the official onsemi MJH11017/D datasheet, revision 11 (October 2024).
Does the MJH11019 support high-side switching configurations?
Yes, the MJH11019 is a PNP Darlington transistor optimized for high-side switching. Its pinout (Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter) and 200 V VCEO(sus) rating enable direct integration into high-side motor driver and relay control circuits where the emitter connects to the positive rail. The MJH11019 datasheet explicitly validates this usage in Figure 4 (FBSOA) and Figure 5 (RBSOA) under clamped inductive conditions.
What package options are available for the MJH11019?
The MJH11019 is offered in two industry-standard packages: TO-247 (Case 340L, Style 3) and TO-218 (Case 340D, Style 1), both Pb-free and marked with suffix "G". Per onsemi's ordering information, both variants share identical electrical specifications and pinout, with TO-247 being the default package effective June 2012 (FPCN# 16827). Thermal resistance (RJC = 0.83°C/W) is specified for both.
How does the MJH11019's Darlington configuration affect base drive requirements?
The MJH11019's monolithic Darlington structure delivers hFE ≥ 400 at IC = 10 Adc, reducing required base current to ≤25 mA for full saturation - significantly less than a single BJT would demand. However, VBE(on) is 2.8 Vdc (typical), and VBE(sat) reaches 3.8 Vdc at IC = 15 Adc/IB = 150 mA, necessitating base drive capable of ≥4 V compliance. This behavior is documented in the "Electrical Characteristics" table of the MJH11017/D datasheet.
Is the MJH11019 suitable for use in inductive load switching applications?
Yes - the MJH11019 is explicitly characterized for inductive switching, with Reverse Bias Safe Operating Area (RBSOA) data provided in Figure 5 of the datasheet. It sustains 100 V at 10 A during turn-off at TC = 100°C under 10% duty cycle, validated with active clamping. Its Cob = 400–600 pF and storage time ts = 2.7 µs (PNP) ensure predictable, non-avalanche turn-off behavior in relay and solenoid drivers.
