Product details

Overview

MJE13005 from onsemi is an NPN silicon power transistor designed for high-voltage, high-speed switching in inductive circuits-specifically 115 V and 220 V SWITCHMODE applications including switching regulators, motor controls, solenoid/relay drivers, and horizontal deflection circuits. It delivers 4 A continuous collector current, sustains 400 V collector-emitter voltage (V_CEO(sus)), and achieves 180 ns typical crossover time (t_c) at 100 °C with 3 A inductive load.

For engineers reviewing the MJE13005 datasheet, MJE1305 pinout, MJE13005 application, or MJE13005 equivalent, key selection criteria include its reverse-bias SOA compliance at 100 °C, 700 V blocking capability under clamped inductive turn-off, low 0.5–1.0 V V_CE(sat) across 1–4 A, and thermal resistance of 1.67 °C/W junction-to-case-critical for high-reliability power conversion designs.

Technical Context

The MJE13005 operates as a high-voltage NPN bipolar junction transistor optimized for fast inductive switching, not linear amplification. Its design emphasizes robust reverse-bias safe operating area (RBSOA) performance under clamped conditions, with guaranteed t_c ≤ 320 ns and t_sv ≤ 4 μs at 100 °C and 3 A-enabling efficient energy transfer in flyback and forward converters.

It features a TO-220AB package with emitter-base voltage rating of 9 V, second-breakdown-limited SOA validated per Figure 11 and 12, and thermal derating of 0.6 W/°C above 25 °C at case temperature-supporting stable operation up to +150 °C junction temperature in thermally managed layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO(sus)	400 V - Sustains rated collector-emitter voltage with 10 mA collector current and open base; defines maximum DC blocking in non-avalanche switching.
V_CEV	700 V - Peak non-repetitive blocking voltage under clamped inductive turn-off; enables use in 220 VAC-derived topologies with margin.
I_C (continuous)	4 A - Maximum steady-state collector current at T_C = 25 °C; derates to ~2.5 A at T_C = 100 °C per thermal limits.
t_c (inductive)	180 ns (typ) at 3 A, 100 °C - Crossover time between 10% V_clamp and 10% I_C; directly determines switching loss P_SWT = ½·V_CC·I_C·t_c·f.
R_JC	1.67 °C/W - Junction-to-case thermal resistance; enables 75 W dissipation at T_C = 25 °C, critical for heatsink sizing.
h_FE	10–60 at I_C = 1–2 A, V_CE = 5 V - DC current gain range informs base drive design; requires ≥0.5 A peak base current for full 4 A saturation.
V_CE(sat)	0.5–1.0 V at I_C/I_B = 4 - Low saturation voltage reduces conduction loss in hard-switched topologies.

Pinout & Package

Supplied in TO-220AB (Case 221A-09) package with vertical mounting orientation, metal tab electrically connected to collector, and 3-pin configuration: Pin 1 = Base, Pin 2 = Collector (tab), Pin 3 = Emitter.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Base	Control terminal requiring ≥0.5 A peak drive for full 4 A switching; reverse-biased during turn-off to extend RBSOA.
Pin 2	Collector	High-voltage power input terminal; electrically tied to metal tab-must be insulated from heatsink unless referenced to same potential.
Pin 3	Emitter	Power return path; low-inductance connection essential for minimizing switching overshoot in inductive loads.

Key Features

Feature	Design Value
Reverse Bias SOA @ 100 °C	Validated clamped inductive turn-off capability up to 300 V clamp voltage and 3 A, enabling reliable operation in high-temp motor drives.
Inductive Switching Matrix	Guaranteed t_c ≤ 320 ns and t_sv ≤ 4 μs at 100 °C and 3 A-key metric for high-frequency SMPS efficiency.
700 V Blocking Capability	Non-repetitive V_CEV rating supports 220 VAC line-fed converters with surge margin and snubber design flexibility.
Pb-Free & RoHS Compliant	Meets EU RoHS Directive 2011/65/EU; compatible with lead-free reflow profiles up to 275 °C for 5 seconds at lead tip.
TO-220AB Mechanical Robustness	Standardized 3-pin outline with 2.54 mm pin pitch and 4.8 mm pin length-ensures compatibility with automated through-hole assembly.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN high-voltage power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJE13003G	Lower V_CEO(sus) (400 V same), lower I_C (1.5 A continuous), higher V_CE(sat) (1.2 V typ at 1 A).	Suitable only for <20 W flyback or low-power relay drivers-not for 4 A motor control or 100 W+ SMPS.	Select when thermal budget is tight and peak current ≤1.5 A; avoid where t_c or RBSOA at 100 °C is critical.
ST13005	Same TO-220AB package, identical V_CEO(sus)/I_C/t_c specs, but no published RBSOA data at 100 °C; h_FE min 8 vs. 10.	Lacks documented reverse-bias SOA validation-requires additional layout margin (snubber, gate control) in high-reliability inductive switching.	Acceptable for cost-sensitive, non-critical 115 VAC applications if RBSOA testing is performed externally.

Compared with MJE13005, MJE13003G trades current and switching speed for lower cost and smaller footprint in sub-2 A designs, while ST13005 offers functional equivalence but lacks onsemi's verified RBSOA characterization-making MJE13005 the preferred choice for thermally demanding, high-reliability inductive switching where datasheet-guaranteed 100 °C performance is required.

FAQ

What is the maximum continuous collector current rating for the MJE13005 at 100°C case temperature?

The MJE13005 has a continuous collector current rating of 4 A at T_C = 25 °C, derating linearly to approximately 2.5 A at T_C = 100 °C based on its 0.6 W/°C thermal derating factor and 75 W maximum dissipation at 25 °C. This value assumes adequate heatsinking and adherence to the forward-bias SOA curve in Figure 11 of the official MJE13005 datasheet.

Does the MJE13005 support reverse-biased base operation during turn-off, and why does it matter?

Yes-the MJE13005 is explicitly characterized for reverse-biased base operation during inductive turn-off, with RBSOA data provided in Figure 12. Applying negative base-emitter voltage (e.g., −5 V) during turn-off extends safe operating limits by suppressing secondary breakdown, enabling reliable 300 V clamp operation at 3 A and 100 °C-critical for motor drives and SMPS with active clamping.

Can the MJE13005 replace the MJE13007 in a 220 VAC power supply design?

No-the MJE13007 has higher V_CEO(sus) (600 V) and I_C (8 A), making it unsuitable as a drop-in replacement for the MJE13005. Substituting MJE13005 for MJE13007 risks premature failure under 600 V transients or 8 A peak loads. The MJE13005 is rated for 400 V/4 A; use only where those limits are sufficient and verified against worst-case line surges and load currents.

What is the typical storage time (t_s) of the MJE13005 under resistive load conditions?

The MJE13005 exhibits a typical storage time (t_s) of 1.7 μs under resistive load conditions at V_CC = 125 V, I_C = 2 A, and I_B1 = I_B2 = 0.4 A, as specified in the Switching Characteristics table. This parameter reflects charge removal delay before collector current begins falling and impacts minimum achievable switching frequency in hard-switched topologies.

Is the MJE13005 pin-compatible with the older MJE13005 (non-G) variant?

Yes-the MJE13005G is a Pb-free, RoHS-compliant version of the original MJE13005, sharing identical TO-220AB package dimensions, pinout (Base–Collector–Emitter), electrical specifications, and thermal characteristics. The "G" suffix denotes green packaging; no layout or schematic changes are required when upgrading from MJE13005 to MJE13005G.
