Product details
Overview
PMEM4030NS from NXP Semiconductors (formerly Philips) is a monolithic dual-function discrete module integrating an NPN transistor with 2 A DC collector current and low 280 mV VCEsat at 2 A, plus a 40 V, 1 A Schottky barrier rectifier with guard ring protection - all in a single SOT96-1 (SO8) surface-mount package. It serves as a compact power switch and freewheeling diode pair in DC-to-DC converters and inductive load drivers.
For engineers reviewing the PMEM4030NS datasheet, PMEM4030NS pinout, PMEM4030NS application, or PMEM4030NS equivalent, this device offers verified co-packaged transistor-diode integration for space-constrained switching circuits requiring low conduction loss, high-speed recovery, and thermal robustness up to 150 °C junction temperature.
Technical Context
The PMEM4030NS combines two independently functional silicon die - an NPN bipolar transistor and a planar Schottky rectifier - in a single leadframe-based SOT96-1 package. The transistor features a minimum hFE of 200 at 1 A and exhibits RCEsat as low as 100 mΩ at 2 A/200 mA drive, while the Schottky diode delivers VF ≤ 500 mV at 1 A and IR ≤ 300 µA at 40 V reverse bias.
No shared electrical node exists between the transistor and diode sections; pins 3 (NC), 4–6 (anode/cathodes), and 1–2–7–8 (base/emitter/collectors) are electrically isolated per functional block. Thermal resistance from junction to ambient is 125 K/W with optimized 1 cm² collector pad, enabling sustained 1 W total dissipation under defined PCB conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; supports 24 V and 36 V bus applications with margin. |
| IC (DC) | 2 A - Continuous collector current rating; enables direct driving of medium-power solenoids, relays, and buck converter switches. |
| VR (Diode) | 40 V - Maximum reverse blocking voltage; suitable for 24 V system freewheeling and synchronous rectification in non-isolated DC-DC stages. |
| IF (Diode) | 1 A - Continuous forward current; matches transistor output capability for balanced current-handling in integrated switch/diode topologies. |
| VCEsat | 280 mV @ 2 A/100 mA - Low saturation voltage minimizes I²R losses and self-heating during high-current switching. |
| VF | 460–500 mV @ 1 A - Low forward voltage reduces conduction loss in freewheeling paths, improving efficiency over standard PN diodes. |
| Tj max | 150 °C (transistor), 125 °C (diode) - Dual thermal limits reflect independent die construction; requires layout-aware thermal management. |
Pinout & Package
SOT96-1 (SO8/MS-012) plastic small-outline package: 8-lead, 3.9 mm body width, standard footprint compatible with automated SMT assembly. Mounting pad for collectors (pins 7 & 8) recommended at 1 cm² for full 1 W power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Transistor control input; requires ≥100 mA base drive for full 2 A saturation. |
| 2 | Emiter | Transistor emitter reference; common connection point for base drive return and load ground. |
| 3 | Not connected | Internally unconnected; must remain floating - no external tie or pull-up/down. |
| 4 | Anode | Schottky diode anode; connects to inductive load side or switch node in flyback/freewheeling configurations. |
| 5 | Cathode | Schottky diode cathode; ties to supply rail or ground depending on circuit topology (e.g., cathode to VIN in buck freewheeling). |
| 6 | Cathode | Second cathode terminal - electrically parallel to pin 5; used for lower-inductance routing or current sharing. |
| 7 | Collector | Transistor collector output; high-current path tied to load; shares thermal pad with pin 8. |
| 8 | Collector | Second collector terminal - electrically parallel to pin 7; provides redundant current path and enhanced thermal conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated NPN + Schottky | Eliminates inter-component trace inductance and saves >30% PCB area versus discrete transistor + diode solutions. |
| Guard ring protected diode | Enhances ruggedness against voltage transients and ESD stress in automotive and industrial load-switching environments. |
| Low VCEsat / VF | Reduces combined conduction loss to <1.0 W at 2 A, enabling higher efficiency and smaller heatsinking in space-limited designs. |
| High-speed switching | Diode reverse recovery time not specified but implied by Schottky architecture - enables operation at >100 kHz in DC-DC converters. |
| Thermal derating support | Specified Rth(j-a) = 125 K/W with 1 cm² copper pad allows predictable thermal design for continuous 1 W operation. |
Applications
| DC-to-DC Converters | Inductive Load Drivers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN transistor + Schottky diode module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PMEM4030PS | PNP complement with identical package, VCEO = 50 V, IC = 2 A, but opposite polarity; diode VR = 40 V, IF = 1 A. | Used in high-side switching or complementary push-pull configurations where PNP sourcing is required. | Select PMEM4030PS only when circuit topology demands PNP switching - not a drop-in replacement for PMEM4030NS. |
| STB12NM60N + STPS1H100 | Discrete N-channel MOSFET (12 A, 600 V) + separate 100 V, 1 A Schottky; no integration, larger footprint, higher gate drive complexity. | Suitable for higher-voltage (>40 V) or higher-current (>2 A) applications where PMEM4030NS lacks rating headroom. | Choose only if voltage/current specs exceed PMEM4030NS limits; adds layout complexity and increases BOM count by two. |
Compared with PMEM4030NS, PMEM4030PS offers complementary polarity but identical thermal and electrical envelope, while STB12NM60N+STPS1H100 provides higher voltage/current capability at the cost of integration, size, and drive simplicity.

FAQ
What is the maximum continuous collector current rating for the PMEM4030NS transistor section?
The PMEM4030NS transistor section is rated for 2 A continuous collector current (IC) under standard FR4 PCB mounting conditions with Tamb ≤ 25 °C. At elevated ambient temperatures or reduced copper area, derating applies - e.g., ~1.3 A at 70 °C ambient with standard footprint.
Can the PMEM4030NS be used in place of a standalone NPN transistor and Schottky diode?
Yes, the PMEM4030NS replaces discrete NPN transistors like BC817-40 and Schottky diodes like BAT54 in compact switching applications. Its integrated structure eliminates inter-component trace inductance and reduces PCB area, but pin compatibility must be verified - it uses SOT96-1, not SOT-23 or SOIC packages.
What is the purpose of pins 5 and 6 both being labeled as cathode in the PMEM4030NS?
Pins 5 and 6 are electrically parallel cathode terminals of the integrated Schottky diode. This dual-cathode configuration lowers effective series inductance and improves current sharing during high di/dt events, supporting robust freewheeling in inductive load applications without requiring external paralleling.
Does the PMEM4030NS include any built-in protection features beyond the guard ring?
Yes - the Schottky diode incorporates a guard ring for transient voltage and ESD protection, and the transistor section features absolute maximum ratings including VEBO = 5 V and Tj = 150 °C. However, PMEM4030NS does not include integrated thermal shutdown, current limiting, or avalanche ruggedness beyond datasheet-specified limits.
Is the PMEM4030NS RoHS compliant and halogen-free?
Yes, PMEM4030NS complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The device carries the "Green" marking per NXP's material declaration, and its SOT96-1 package uses lead-free matte tin terminations compatible with standard Pb-free reflow profiles.
