Product details

Overview

MJE13005G 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 I_C = 3 A and T_C = 100°C.

For engineers reviewing the MJE13005G datasheet, pinout, applications, or equivalent options, key selection criteria include its reverse-bias SOA performance under inductive loads, clamped inductive switching speed (t_c, t_sv), 75 W total device dissipation at T_C = 25°C, and Pb-free TO-220AB package compatibility with high-reliability power conversion designs.

Technical Context

The MJE13005G employs a rugged epitaxial base structure optimized for fast turn-off in inductive switching, with guaranteed clamped inductive SOA operation up to 100°C case temperature. Its design emphasizes voltage-controlled safe turn-off under reverse-biased base conditions, supported by documented RBSOA curves (Figure 12) and clamped inductive switching waveforms (Figure 7).

It features a 700 V blocking capability (V_CEV) and second-breakdown-limited forward-bias SOA validated per Figure 11, enabling reliable operation in flyback and forward converter topologies where simultaneous high V_CE and high I_C occur during switching transitions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO(sus)	400 V - Sustained collector-emitter voltage under switching conditions with zero base current; defines maximum usable DC bus voltage in non-clamped inductive circuits.
P_D @ T_C = 25°C	75 W - Maximum continuous power dissipation at case temperature 25°C; requires heatsink design supporting ≤1.67°C/W junction-to-case thermal resistance.
t_c (crossover time)	180 ns (typ) @ I_C = 3 A, T_C = 100°C - Critical timing parameter for calculating switching loss (P_SWT = ½·V_CC·I_C·t_c·f); directly impacts efficiency in high-frequency SMPS.
h_FE	8–40 @ I_C = 2 A, V_CE = 5 V - DC current gain range defining required base drive current (e.g., 0.5 A base current needed for 2 A collector current at h_FE = 4).
V_CE(sat)	1.0 V max @ I_C = 4 A, I_B = 1 A - Saturation voltage determining conduction loss (P_COND = I_C²·R_CE(sat) ≈ I_C·V_CE(sat)) in hard-switched applications.
R_JC	1.67°C/W - Junction-to-case thermal resistance; enables calculation of peak junction temperature rise above heatsink temperature under pulsed or continuous load.

Pinout & Package

Package: TO-220AB (Case 221A-09, Style 1), leaded plastic package with isolated collector tab; compatible with standard TO-220 heatsinks and mounting hardware.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Emitting terminal for majority carriers	Low-impedance return path; must be connected to low-side reference; layout must minimize inductance to avoid voltage spikes during fast turn-off.
2 (Base)	Control electrode for carrier injection	Requires active drive circuit capable of sourcing/sinking ≥4 A peak (I_BM) and sustaining ≥2 A continuous (I_B) for full saturation at high current.
3 (Collector)	Current-collecting terminal	Internally connected to metal tab; electrically isolated from tab per TO-220AB spec; must be mounted to heatsink with insulating washer if system ground is not collector potential.

Key Features

Feature	Design Value
Reverse Bias SOA with Inductive Loads	Validated up to T_C = 100°C (Figure 12); enables reliable operation in clamped inductive turn-off without avalanche stress.
Clamped Inductive Switching Speed	t_c = 180 ns typ @ 3 A, 100°C - reduces switching loss in high-frequency converters (e.g., >50 kHz flyback designs).
700 V Blocking Capability (V_CEV)	Supports 220 VAC-derived 310 VDC bus with margin for line surges and ringing; eliminates need for external snubbers in many 220 V applications.
Pb-Free and RoHS Compliant	G-suffix denotes lead-free termination and halogen-free molding compound; meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for standard assembly.
Thermal Robustness	R_JC = 1.67°C/W and T_J range −65°C to +150°C - supports operation in industrial ambient environments with minimal derating up to 100°C case temperature.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STMicroelectronics BU2508DX	Higher V_CEO(sus) = 800 V; lower I_C = 3 A continuous; TO-220FP package with insulated tab.	Better suited for 380 VDC bus applications; reduced current rating limits use in >3 A motor control loads.	Select when higher voltage margin is critical and current demand ≤3 A; verify thermal interface due to different package footprint.
ON Semiconductor MJE13003G	Lower V_CEO(sus) = 200 V; same TO-220AB package; 1.5 A I_C continuous; faster t_c = 120 ns @ 1 A.	Restricted to 115 VAC-derived supplies; insufficient for 220 VAC input or high-current solenoid drivers.	Choose only for cost-sensitive 115 VAC designs with <2 A load; not a drop-in replacement for MJE13005G in 220 V or 4 A applications.

Compared with BU2508DX and MJE13003G, the MJE13005G uniquely balances 400 V sustain voltage, 4 A current capacity, and 180 ns crossover time in a standard TO-220AB package-making it optimal for universal-input (115/220 VAC) SMPS and industrial motor control where both voltage headroom and current drive are simultaneously required.

FAQ

What is the maximum continuous collector current rating for the MJE13005G?

The MJE13005G has a maximum continuous collector current (I_C) rating of 4 A at T_C = 25°C, as specified in the Absolute Maximum Ratings table. This rating decreases with increasing case temperature-derating linearly at 0.6 W/°C above 25°C for total device dissipation, which indirectly constrains usable I_C under thermal constraints. The MJE13005G must be heatsinked appropriately to maintain T_C ≤ 100°C for sustained 4 A operation.

Does the MJE13005G support operation at elevated temperatures like 100°C case temperature?

Yes, the MJE13005G is explicitly characterized for inductive switching performance at T_C = 100°C, including guaranteed t_c = 180 ns (typ) and validated Reverse Bias SOA (RBSOA) per Figure 12. Its operating junction temperature range extends to +150°C, and thermal resistance R_JC = 1.67°C/W allows accurate junction temperature estimation. The MJE13005G remains fully functional and within specification at 100°C case temperature when operated within SOA limits.

Is the MJE13005G pin-compatible with other TO-220AB NPN transistors such as the MJE13003G?

The MJE13005G uses the standard TO-220AB (Case 221A-09) package with E-B-C pinout (Emitter-Base-Collector), matching the physical pin configuration of the MJE13003G and other members of the MJE1300x family. However, it is not a direct functional replacement due to differences in V_CEO(sus) (400 V vs. 200 V), I_C rating (4 A vs. 1.5 A), and SOA boundaries. PCB layout may be reused, but electrical validation is required before substitution.

What does the 'G' suffix in MJE13005G signify?

The 'G' suffix in MJE13005G indicates a Pb-free (lead-free) and RoHS-compliant package per onsemi's standard marking convention. It confirms that the device uses lead-free terminations and halogen-free molding compound, meeting JEDEC JS709B and IPC-1752A requirements. The MJE13005G is rated for standard SnPb and lead-free reflow profiles, with maximum lead temperature of 275°C for 5 seconds at 1/8″ from case.

Can the MJE13005G be used in avalanche mode for unclamped inductive switching?

No-the MJE13005G is not rated or characterized for unclamped avalanche operation. Its Safe Operating Area data (Figures 11 and 12) and application guidance explicitly assume clamped inductive switching conditions. The datasheet warns against exceeding RBSOA limits and notes that reverse-bias SOA is verified under clamped conditions "so that the device is never subjected to an avalanche mode." Using the MJE13005G without clamping risks second breakdown and permanent failure.
