Product details
Overview
MMBT6589T1G from onsemi is a high-current PNP silicon switching transistor in TSOP-6 package, rated for −30 V VCEO, −2.0 A peak collector current, and 925 mW power dissipation on 1.0×1.0 inch FR-4 pad. It delivers hFE ≥ 80 at −1.0 A and VCE(sat) ≤ −0.30 V at −1.0 A/−0.1 A drive, optimized for load management in portable battery-powered systems.
For engineers reviewing the MMBT6589T1G datasheet, pinout, applications, or equivalent options, key selection criteria include verified PNP switching capability, thermal performance under pulsed load conditions, ESD robustness (HBM Class 3), and Pb-free TSOP-6 compatibility with automated SMT assembly.
Technical Context
This device operates as a single high-current PNP bipolar junction transistor-no integrated biasing, logic, or protection circuitry. Its electrical behavior follows standard BJT DC and switching characteristics, with gain degradation above −1.0 A and saturation voltage increasing to −0.65 V at −2.0 A drive.
Thermal performance depends critically on PCB layout: RJA is 135 °C/W with 1.0×1.0 inch copper pad but degrades to 230 °C/W on minimum FR-4 pad. Safe operating area (SOA) is defined for single-pulse durations up to 10 s, with derating applied above 25°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −30 V - Maximum allowable collector-emitter voltage before breakdown during switching off-state |
| IC (cont.) | −1.0 A - Continuous DC current handling capacity at TA = 25°C with adequate heatsinking |
| VCE(sat) | ≤ −0.30 V at IC = −1.0 A, IB = −0.1 A - Low saturation voltage enables <0.3 W conduction loss per switch |
| hFE | ≥ 80 at IC = −1.0 A, VCE = −2.0 V - Sufficient current gain to support simple resistor-biased base drive |
| fT | ≥ 100 MHz - Supports switching frequencies up to ~10–20 MHz with acceptable gain margin |
| RJA | 135 °C/W (1.0×1.0″ pad) - Thermal resistance defines maximum power before junction exceeds 150°C |
| ESD Rating | HBM Class 3 (>8 kV), MM Class C - Robust enough for handheld assembly without special ESD controls |
Pinout & Package
Package: TSOP-6 (Case 318G, Style 7), 3.00 × 1.50 × 0.90 mm, 0.95 mm pitch, Pb-free (G-suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5 | Collector | Common high-side connection point; electrically tied internally for parallel current handling |
| 3 | Base | Control input requiring negative current injection to turn on; typical RB ≈ 10–22 Ω for −1.0 A switching |
| 6 | Emiter | Power return node; connected to system ground or battery negative in high-side load switch configurations |
| 4 | No Connect | Internally unconnected; must remain floating-no routing or soldering required |
Key Features
| Feature | Design Value |
|---|---|
| Pb-free TSOP-6 package | RoHS-compliant surface-mount footprint compatible with IPC-7351B standard land patterns |
| High peak current rating | −2.0 A pulsed capability supports motor startup, LED flash, or capacitor charging surges |
| Low VCE(sat) at high IC | −0.30 V at −1.0 A reduces conduction loss by >40% vs. legacy PNP transistors like MMBT2907A |
| Thermally enhanced layout | 925 mW dissipation on 1.0×1.0 inch pad enables use without external heatsink in space-constrained portable designs |
| ESD-hardened structure | HBM Class 3 rating eliminates need for external TVS diodes in consumer-grade handheld PCBs |
Applications
| Smartphone Power Sequencing | Wireless Headset Battery Protection |
|---|---|
|
Use Scenario: Controlled enable/disable of PMIC rails during boot-up and sleep transitions. IC Role / Device Role / Timing Role: High-side PNP switch isolating VBAT from downstream LDO inputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ZXTN25050DFHTA | Higher VCEO (−50 V), lower hFE (min 50 @ −1 A), SOT-23-6 package | Preferred where higher breakdown margin is needed, but requires larger base drive due to lower gain | Select when system voltage exceeds 30 V or board space allows SOT-23-6; not drop-in due to different pinout and smaller thermal pad |
| MMBT2907ALT1G | Lower IC (−600 mA), higher VCE(sat) (−0.65 V @ −500 mA), same TSOP-6 footprint | Suitable for <500 mA loads where thermal budget is less constrained | Use only if peak current stays below −0.6 A; MMBT6589T1G provides 67% higher current capacity and 54% lower conduction loss at rated load |
Compared with ZXTN25050DFHTA and MMBT2907ALT1G, the MMBT6589T1G uniquely balances high current (−1.0 A), low saturation voltage (−0.30 V), and thermally optimized TSOP-6 layout-making it the preferred choice for compact, high-efficiency portable load switching where both performance and manufacturability matter.

FAQ
What is the maximum continuous collector current rating for MMBT6589T1G?
The MMBT6589T1G is rated for −1.0 A continuous collector current at TA = 25°C with a 1.0×1.0 inch copper pad. Derating applies above 25°C ambient-7.4 mW/°C-so at 70°C ambient, max continuous current drops to approximately −0.66 A. This rating assumes proper PCB thermal design per datasheet Note 2.
Does MMBT6589T1G have a built-in base resistor or logic-level interface?
No, the MMBT6589T1G is a bare PNP bipolar transistor with no integrated base resistors or level-shifting circuitry. It requires external base current control-typically via a series resistor from a microcontroller GPIO or dedicated driver. Base-emitter turn-on voltage is −1.1 V at −1.0 A collector current.
Can MMBT6589T1G be used in high-frequency switching applications?
Yes-the MMBT6589T1G has a minimum fT of 100 MHz, supporting switching frequencies up to ~10–20 MHz in well-designed circuits. However, its SOA and thermal limits constrain duty cycle and pulse width; for >100 kHz PWM, verify safe operating area using Figure 7 and apply appropriate gate/base drive strength.
What is the meaning of "Style 7" in the MMBT6589T1G package marking diagram?
"Style 7" refers to the internal pin configuration for the TSOP-6 package: Pin 1 = Collector, Pin 2 = Collector, Pin 3 = Base, Pin 4 = No Connect, Pin 5 = Collector, Pin 6 = Emitter. This layout maximizes collector current handling through three parallel pins while isolating the base and emitter for clean control and return paths.
Is MMBT6589T1G suitable for automotive applications?
The MMBT6589T1G is not AEC-Q101 qualified and is specified for −55°C to +150°C junction temperature, but lacks automotive-specific qualification, stress testing, or PPAP documentation. It may be used in non-safety-critical automotive accessories only after full system-level validation-including thermal, EMC, and lifetime reliability testing.
