Product details
Overview
MJH11022 from onsemi is an NPN complementary Darlington silicon power transistor designed for high-current, medium-voltage linear amplification and switching in motor control, industrial power supplies, and audio output stages. It delivers 15 A continuous collector current, sustains 250 Vdc collector-emitter voltage, and achieves minimum DC current gain of 400 at 10 Adc - enabling robust drive capability in high-power analog and switching circuits.
For engineers reviewing the MJH11022 datasheet, pinout, applications, or equivalent options, key selection criteria include its 250 VCEO(sus) rating, 150 W total device dissipation at TC = 25°C, TO-247/TO-218 package thermal performance (RJC = 0.83°C/W), and verified Darlington architecture with monolithic construction and Pb-free compliance.
Technical Context
The MJH11022 implements a monolithic Darlington pair configuration with integrated base-emitter resistor network, delivering high hFE (≥400 @ IC = 10 A) while maintaining low VCE(sat) (1.8 V typ @ IC = 10 A). Its safe operating area (SOA) is characterized for both forward-bias (FBSOA) and reverse-bias (RBSOA) conditions up to 150°C junction temperature.
Thermal design relies on case-mounted heat sinking with RJC = 0.83°C/W maximum; power derating begins above 25°C at 1.2 W/°C. Switching behavior is defined by td = 150 ns, tr = 1.2 µs, ts = 4.4 µs, and tf = 2.5 µs under clamped 100 V, 10 A test conditions - confirming suitability for moderate-speed switching in inductive load circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO(sus) | 250 Vdc minimum - supports operation in 200–240 VAC line-connected motor drives and high-voltage DC power stages without avalanche stress. |
| IC (Continuous) | 15 Adc - enables direct drive of solenoids, relay coils, and small DC motors without external current boosting. |
| hFE (Min) | 400 @ IC = 10 Adc, VCE = 5 V - reduces required base drive current to ≤25 mA for full 10 A output, easing microcontroller interface. |
| VCE(sat) (Typ) | 1.8 V @ IC = 10 A, IB = 100 mA - limits conduction loss to 18 W at 10 A, supporting thermally constrained PCB layouts. |
| RJC | 0.83°C/W max - allows ≥120 W dissipation with 100°C case-to-ambient ΔT using standard heatsinks. |
| Cob | 400 pF @ VCB = 10 V - sets upper limit on switching speed in high-frequency amplifier applications; impacts Miller effect in common-emitter configurations. |
| fT | 3.0 MHz - defines usable bandwidth for linear amplification up to ~100 kHz with stable gain margin in emitter-follower configurations. |
Pinout & Package
Package: TO-247 (Case 340L, Style 3) or TO-218 (SOT-93, Case 340D, Style 1); both are 3-pin, isolated-tab power packages with collector connected to tab for direct heatsink mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Control input node for Darlington pair | Accepts low-current drive signal; requires ≥100 mA peak for full 15 A saturation; internal base resistor network simplifies biasing. |
| 2 (Collector) | Main high-current output terminal | Electrically tied to metal tab; must be insulated from heatsink unless system ground reference permits direct mounting. |
| 3 (Emitter) | Power return path and current sense reference | Provides low-impedance return for load current; used for emitter degeneration or current sensing in linear regulator designs. |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic Darlington construction | Eliminates discrete interconnect parasitics and matching drift, ensuring stable hFE over temperature and lifetime. |
| 250 VCEO(sus) rating | Enables use in 240 VAC rectified bus applications (e.g., universal input SMPS PFC stages) without external snubbers. |
| Pb-free TO-247/TO-218 packaging | Meets RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) for unlimited floor life. |
| 150 W power dissipation @ TC = 25°C | Supports high-duty-cycle operation in Class AB audio amplifiers and DC motor H-bridge half-bridges with active thermal management. |
| Low VBE(sat) = 3.8 V @ IC = 15 A | Reduces base drive power loss to <600 mW at full load, minimizing driver stage heating in multi-transistor arrays. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN Darlington power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BDW84C | Lower VCEO(sus) = 100 V, lower hFE = 750 min @ IC = 5 A, TO-220 package (RJC = 3.0°C/W). | Not suitable for >120 VDC bus applications; limited to low-voltage motor control and relay drivers. | Select BDW84C only when cost sensitivity outweighs voltage headroom and thermal performance requirements. |
| MJ15003G | Higher VCEO = 250 V, but single bipolar (not Darlington); hFE = 20 min @ IC = 8 A; TO-3 package (RJC = 1.5°C/W). | Requires external base drive amplification; better suited for ultra-low VCE(sat) (<1.0 V) linear regulator applications. | Choose MJ15003G when lowest possible saturation loss is critical and base drive circuitry is already available. |
Compared with BDW84C and MJ15003G, the MJH11022 uniquely combines 250 V sustain voltage, Darlington-level current gain, and TO-247 thermal efficiency - making it the only option among the three capable of 15 A switching at 200 VDC without auxiliary cooling or gate drivers.

FAQ
What is the maximum continuous collector current rating for the MJH11022?
The MJH11022 has a maximum continuous collector current (IC) rating of 15 Adc at TC = 25°C. Derating applies above this temperature at 1.2 W/°C, and peak pulsed current is rated at 30 Adc under specified pulse conditions (5.0 ms, 10% duty cycle). This rating is validated per the onsemi datasheet revision 11, October 2024.
Does the MJH11022 have a built-in base-emitter resistor?
Yes, the MJH11022 integrates a monolithic Darlington structure with internal base-emitter resistors, eliminating the need for external bias components in most switching applications. This design ensures consistent turn-on characteristics and reduces PCB component count compared to discrete Darlington implementations.
Can the MJH11022 be used in parallel configurations for higher current handling?
Parallel operation of MJH11022 devices is not recommended without individual emitter resistors due to inherent hFE and VBE(on) mismatches between units. The datasheet does not specify matched pairs or thermal tracking data, and unbalanced current sharing may lead to thermal runaway under sustained load.
What is the safe operating area (SOA) limitation for MJH11022 at 100°C case temperature?
At TC = 100°C, the MJH11022's forward-bias SOA (FBSOA) restricts operation to ≤8 A at 100 VCE or ≤4 A at 200 VCE for DC conditions. These limits derive from thermal constraints and second-breakdown boundaries shown in Figure 4 of the onsemi datasheet, and must be strictly observed to prevent catastrophic failure.
Is the MJH11022 pin-compatible with MJH11018 or MJH11020?
Yes, the MJH11022 shares identical pinout (Base–Collector–Emitter), package footprint (TO-247/TO-218), and terminal assignments with MJH11018 and MJH11020. However, it is not functionally interchangeable without circuit review due to its higher 250 VCEO(sus) rating and associated SOA differences - especially in voltage-clamped or inductive-switching applications.
