Product details
Overview
MJH11017 from onsemi is a PNP complementary Darlington silicon power transistor designed for low-frequency switching and motor control applications. It delivers 15 A continuous collector current, sustains 150 Vdc collector-emitter voltage (VCEO(sus)), and achieves minimum DC current gain (hFE) of 400 at 10 Adc - enabling high-current amplification with minimal base drive in industrial power stages.
For engineers reviewing the MJH11017 datasheet, pinout, applications, or equivalent options, key selection criteria include its 150 V/15 A rating, TO-218 (SOT-93) or TO-247 package options, low VCE(sat) of 1.2 V @ 5 A, thermal resistance of 0.83 °C/W, and suitability for linear amplifier and inductive load switching where robust second-breakdown SOA is required.
Technical Context
The MJH11017 is a monolithic PNP Darlington pair with integrated driver and output transistors, optimized for high DC current gain and rugged safe operating area (SOA) under both forward-bias (FBSOA) and reverse-bias (RBSOA) conditions. Its design supports stable operation up to 150 °C junction temperature and features Pb-free construction per RoHS.
It exhibits typical VCE(sat) of 1.2 V at IC = 5.0 A and 1.8 V at IC = 10 A, with VBE(on) of 2.8 V and VBE(sat) of 3.8 V under rated conditions. Small-signal current gain (hfe) is 75 at 10 A/3 V/1 kHz, while fT is 3.0 MHz - confirming suitability for audio-frequency and <100 kHz switching rather than RF or high-speed digital use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO(sus) | 150 Vdc minimum - defines maximum sustainable collector-emitter voltage during switching with zero base current, critical for inductive load snubbing design |
| IC (Continuous) | 15 Adc - usable continuous collector current at TC = 25 °C; derates linearly above 25 °C per 1.2 W/°C |
| hFE (Min) | 400 @ IC = 10 Adc, VCE = 5 Vdc - enables low base drive current (e.g., ~25 mA) for full 10 A output, reducing driver stage complexity |
| VCE(sat) (Typ) | 1.2 V @ IC = 5.0 A, IB = 50 mA - limits conduction loss to ≤6 W at 5 A, supporting thermally constrained PCB layouts |
| RJC | 0.83 °C/W - allows 150 W dissipation with only 124.5 °C rise from case to junction at max PD, easing heatsink selection |
| Cob | 400–600 pF @ VCB = 10 Vdc, f = 0.1 MHz - impacts turn-off speed and gate/base drive impedance matching in switching circuits |
| td / tr / ts / tf | 75 ns / 0.5 μs / 2.7 μs / 2.5 μs (PNP) - defines switching timing envelope for <50 kHz PWM motor drives and relay replacements |
Pinout & Package
Package: TO-218 (SOT-93, Case 340D) or TO-247 (Case 340L), both 4-pin configurations with dual collector terminals for enhanced current handling and thermal path. Pin 1 = Base, Pin 2 = Collector, Pin 3 = Emitter, Pin 4 = Collector (redundant collector connection).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Base | Control input requiring ~25 mA for full 10 A conduction; high hFE reduces driver burden vs. single bipolar devices |
| Pin 2 & Pin 4 | Collector (dual) | Parallel collector terminals lower effective lead inductance and spreading resistance; must be connected together externally |
| Pin 3 | Emitter | Power return path; tied to system ground or negative rail in PNP high-side switch configurations |
Key Features
| Feature | Design Value |
|---|---|
| High hFE ≥ 400 @ 10 A | Reduces base drive requirements by >10× versus standard power transistors, enabling direct microcontroller GPIO or low-power op-amp drive |
| 150 V VCEO(sus) rating | Supports 120 VAC line-connected loads and 100 VDC bus systems with margin for inductive kickback without external clamping |
| FBSOA/RBSOA curves | Validated safe operating area up to 150 °C case temperature ensures reliability in motor stall, short-circuit, and regenerative braking events |
| Monolithic Darlington structure | Eliminates inter-device parameter mismatch and thermal tracking issues found in discrete Darlington pairs, improving consistency |
| Pb-free TO-218/TO-247 packages | Enables RoHS-compliant industrial assembly; TO-247 offers improved thermal performance and mechanical robustness over TO-218 |
Applications
| DC Motor Control | Linear Audio Amplifier Output Stage |

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 |
|---|---|---|---|
| MJH11019 | 200 V VCEO(sus) min, same package and pinout | Higher voltage margin for 160 VDC bus or 230 VAC rectified systems | Select when operating above 150 V or requiring extended avalanche margin |
| BDW53C | 100 V VCEO(sus), TO-220 package, hFE = 750 min @ 3 A | Lower voltage rating but higher hFE at moderate current; smaller footprint | Prefer for space-constrained 48 VDC designs where 100 V margin suffices and thermal budget allows TO-220 |
Compared with MJH11017, MJH11019 offers +50 V headroom for higher-voltage DC buses without changing layout, while BDW53C trades voltage capability for higher gain and smaller package - making it suitable for lower-voltage, space-sensitive applications where 100 V suffices.

FAQ
What is the maximum continuous collector current rating for the MJH11017 at 25°C case temperature?
The MJH11017 has a maximum continuous collector current (IC) rating of 15 Adc at TC = 25°C. This rating decreases linearly with rising case temperature at 1.2 W/°C derating - meaning at 100°C case temperature, the usable continuous current drops to approximately 6 A based on its 150 W total dissipation limit and 0.83 °C/W thermal resistance. Always verify actual junction temperature using RJC and ambient conditions in final layout.
Does the MJH11017 support direct microcontroller GPIO drive without an external driver transistor?
The MJH11017 can be driven directly by many microcontroller GPIOs under light-load conditions, thanks to its minimum hFE of 400 at 10 Adc - requiring only ~25 mA base current for full conduction. However, for reliable 15 A switching or fast turn-on/turn-off, a dedicated driver (e.g., ULN2003 or discrete BJT stage) is recommended to ensure sufficient IB during transient peaks and maintain VBE(sat) stability. The MJH11017 datasheet specifies VBE(on) = 2.8 V and VBE(sat) = 3.8 V, confirming significant base-emitter voltage drop.
What is the difference between MJH11017 and MJH11019 in terms of voltage rating and compatibility?
The MJH11017 is rated for 150 Vdc minimum collector-emitter sustaining voltage (VCEO(sus)), while the MJH11019 is rated for 200 Vdc - a +50 V increase. Both share identical pinout (TO-218/TO-247), thermal characteristics (RJC = 0.83 °C/W), and electrical behavior (hFE ≥ 400, VCE(sat) ≈ 1.2–1.8 V). They are not pin-compatible drop-in replacements due to differing voltage safety margins; substituting MJH11017 for MJH11019 in a 200 V system risks premature failure under transient overvoltage.
Can the MJH11017 be used in parallel configurations to increase current handling?
Yes, the MJH11017 supports paralleling due to its monolithic Darlington construction and inherent current-sharing characteristics - unlike discrete transistor pairs, which suffer from thermal runaway. However, external emitter resistors (typically 0.1 Ω) are still recommended to balance dynamic current distribution during switching transients. Thermal coupling between devices must be minimized via separate heatsink zones or shared thermal mass with uniform mounting pressure to prevent localized hot spots.
Is the MJH11017 suitable for high-frequency switching applications such as >100 kHz SMPS?
No, the MJH11017 is not suitable for high-frequency switching above ~50 kHz. Its specified fT is 3.0 MHz, but switching times (ts = 2.7 μs, tf = 2.5 μs) and Cob = 400–600 pF result in excessive switching losses and thermal stress at high frequencies. The device is explicitly characterized for low-frequency switching and linear amplification - per its datasheet description as "general purpose amplifiers, low frequency switching and motor control applications." For SMPS, MOSFETs or RF-optimized BJTs are preferred.
