Product details
Overview
NSS60601MZ4T3G from onsemi is an NPN low VCE(sat) transistor rated for 60 V collector-emitter voltage, 6.0 A continuous collector current, and 2.0 W power dissipation in SOT-223 package. It delivers ultra-low saturation voltage (0.040 V typ. at IC = 6.0 A), high DC current gain (50–360), and fast switching (tr = 115 ns, tf = 125 ns), enabling efficient energy control in portable DC-DC converters.
For engineers reviewing the NSS60601MZ4T3G datasheet, pinout, applications, or equivalent options, key selection criteria include verified VCE(sat) performance at 6 A, thermal resistance of 64 °C/W with 645 mm² copper, AEC-Q101 qualification status, and compatibility with PMU-driven base control in battery-powered systems.
Technical Context
This device belongs to onsemi's e2PowerEdge family and uses a planar epitaxial silicon structure optimized for low-voltage, high-current switching. Its linear gain (Beta) behavior across IC = 0.5–6.0 A supports both digital switching and analog amplification roles without gain collapse.
The SOT-223 package features two collector terminals (Pins 2 & 4) for enhanced thermal and current handling, while the emitter-base breakdown voltage (6.0 V) and fT = 100 MHz enable stable operation in high-speed PWM control loops up to several hundred kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCE(sat) max | 0.300 V at IC = 6.0 A, IB = 0.6 A - enables <150 mW conduction loss in 6 A load switches |
| hFE min | 50 at IC = 6.0 A, VCE = 2.0 V - ensures reliable saturation with modest base drive (≤10% IC) |
| PD (with 645 mm² Cu) | 2.0 W at TA = 25 °C - supports sustained 6 A operation with PCB-level heatsinking |
| RJA | 64 °C/W - allows junction temperature rise ≤128 °C under 2 W dissipation at ambient 25 °C |
| fT | 100 MHz - supports stable small-signal amplification and high-frequency switching control |
| V(BR)CEO | 60 V - provides margin for 48 V bus transients and flyback voltage clamping in buck converters |
| ts | 1350 ns - defines minimum off-time in hard-switched topologies; impacts maximum practical PWM frequency |
Pinout & Package
SOT-223 (TO-261, Case 318E-04) surface-mount package with exposed thermal pad connected to collector; footprint compatible with JEDEC TO-261 standards and supports manual reflow or automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input requiring ~0.6–0.9 V turn-on; driven directly by PMU GPIO or logic-level PWM |
| 2 | Collector | Main high-current output path; electrically tied to Pin 4 for parallel current sharing and thermal spreading |
| 3 | Emiter | Reference node for load return; connects to ground or low-side shunt resistor for current sensing |
| 4 | Collector | Second collector terminal - must be connected to same net as Pin 2 to maintain rated current and thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VCE(sat) | 0.040 V typical at 6 A - reduces conduction losses by >50% vs. standard NPNs, critical for portable battery runtime |
| AEC-Q101 qualified | Validated for automotive airbag and instrument cluster use - includes stress testing per automotive reliability standards |
| Linear hFE curve | hFE = 150–360 across IC = 0.5–1.0 A - enables predictable analog gain in sensor interface or pre-driver stages |
| High fT bandwidth | 100 MHz - supports clean signal integrity in feedback paths and high-frequency gate driving circuits |
| Pb-Free / RoHS | Halogen-free, BFR-free construction - meets global environmental compliance requirements for industrial and consumer products |
Applications
| DC-DC Buck Converter | Portable Device Power Management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN low VCE(sat) transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MBT3904DW1T1G | Lower IC rating (200 mA), higher VCE(sat) (0.2 V @ 50 mA), SOT-363 package | Only suitable for signal-level or low-power switching - not a replacement for 6 A loads | Select only for biasing, logic translation, or low-current sensing where thermal and current capacity are non-critical. |
| ZXTN2012ZTA | Higher VCE(sat) (0.17 V @ 6 A), similar SOT-223, no AEC-Q101 qualification | Lacks automotive qualification; thermal RJA = 70 °C/W vs. 64 °C/W - requires larger copper area for same power | Acceptable for industrial DC-DC if AEC-Q101 is not required and layout allows extra thermal relief. |
Compared with MBT3904DW1T1G and ZXTN2012ZTA, the NSS60601MZ4T3G uniquely combines 6 A current handling, sub-0.05 V VCE(sat), and AEC-Q101 qualification in SOT-223 - making it the only option among the three for automotive-grade, high-current, low-loss switching.

FAQ
What is the maximum continuous collector current for the NSS60601MZ4T3G?
The NSS60601MZ4T3G is rated for 6.0 A continuous collector current at TA = 25 °C with sufficient PCB copper (645 mm², 1 oz). Derating applies above 25 °C at 15.6 mW/°C, limiting usable current in high-ambient environments unless additional heatsinking is applied. This rating is confirmed in the "Maximum Ratings" table on page 1 of the official datasheet.
Is the NSS60601MZ4T3G AEC-Q101 qualified?
Yes, the NSS60601MZ4T3G is AEC-Q101 qualified and PPAP capable, as explicitly stated in the "Features" section and ordering information table. The NSV-prefix variant (NSV60601MZ4T3G*) is designated for automotive applications, but the NSS60601MZ4T3G itself shares the same qualification and test data per onsemi documentation.
How does the dual-collector pin configuration (Pins 2 and 4) affect PCB layout for the NSS60601MZ4T3G?
Both Pins 2 and 4 are collector terminals and must be connected to the same high-current net - typically the input voltage rail or switched node. Failing to tie them together compromises current rating, thermal performance, and may cause localized overheating. The SOT-223 footprint must allocate adequate copper area to both pins to achieve the rated 2.0 W dissipation.
What is the typical VCE(sat) of the NSS60601MZ4T3G at 6 A collector current?
The typical VCE(sat) of the NSS60601MZ4T3G is 0.040 V at IC = 6.0 A, IB = 0.6 A, and VCE = 2.0 V, per the "Electrical Characteristics" table on page 3 of the datasheet. This value is measured under pulsed conditions (300 µs, ≤2% duty cycle) and represents best-case conduction loss in properly biased switching applications.
Can the NSS60601MZ4T3G be used in analog amplifier configurations?
Yes, the NSS60601MZ4T3G supports analog amplifier use due to its linear DC current gain (hFE) profile - ranging from 150 at 500 mA to 100 at 2.0 A - and stable fT of 100 MHz. Its VBE(on) of 0.900 V at IC = 1.0 A enables predictable biasing, and the device is explicitly cited in the datasheet as "ideal components in analog amplifiers."
