Product details
Overview
PUMD18 from Nexperia is an AEC-Q101-qualified NPN/PNP resistor-equipped double transistor (RET) in SOT363-3 (SC-88) package, rated for 50 V VCEO, 100 mA output current per transistor, with integrated bias resistors R1 = 4.7 kΩ and R2 = 10 kΩ. It functions as a dual-channel digital switch for level-shifting and signal inversion in low-power logic interfaces.
For engineers reviewing the PUMD18 datasheet, PUMD18 pinout, PUMD18 application, or PUMD18 equivalent, this device supports compact board layout in automotive body electronics, I/O buffering, and replacement of discrete transistor pairs in space-constrained digital control circuits.
Technical Context
The PUMD18 integrates two complementary silicon transistors - TR1 (NPN) and TR2 (PNP) - each with monolithically embedded base bias resistors, eliminating external components for standard switching configurations. Its dual-transistor topology enables push-pull or complementary logic-level translation without external pull-up/pull-down networks.
Each transistor operates independently with verified DC current gain (hFE ≥ 50 at IC = 10 mA), collector-emitter saturation voltage ≤ 100 mV, and transition frequencies of 230 MHz (TR1) and 180 MHz (TR2), supporting high-speed digital switching up to ~50 MHz in typical buffered applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage for both NPN and PNP transistors under open-base conditions. |
| IO | 100 mA - Continuous output current capability per transistor, enabling direct drive of LEDs, small relays, or logic inputs. |
| R1 | 4.7 kΩ ±28% - Integrated input bias resistor for each transistor, setting base current for predictable turn-on behavior. |
| R2/R1 ratio | 2.1 - Fixed internal resistor ratio ensuring stable bias network performance across temperature and process variation. |
| hFE | ≥50 - Minimum DC current gain at VCE = 5 V, IC = 10 mA, ensuring reliable saturation with modest base drive. |
| fT | 230 MHz (TR1), 180 MHz (TR2) - Transition frequency confirming suitability for fast digital switching and moderate-frequency signal conditioning. |
| Ptot (device) | 300 mW - Total power dissipation limit at Tamb ≤ 25 °C on FR4 PCB, defining thermal design margin for dual-transistor operation. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mounted package with 0.65 mm pitch, 2.2 mm × 1.35 mm footprint, and exposed pad-compatible thermal profile.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1 (NPN); common reference node for first transistor channel. |
| 2 | I1 | Base input for TR1 (NPN); driven through internal R1–R2 network for self-biased switching. |
| 3 | O2 | Collector output for TR2 (PNP); active-low output stage in complementary pair configuration. |
| 4 | GND2 | Emiter connection for TR2 (PNP); independent ground reference for second transistor channel. |
| 5 | I2 | Base input for TR2 (PNP); polarity-inverted input path with matched biasing to I1. |
| 6 | O1 | Collector output for TR1 (NPN); active-high output stage, forming push-pull pair with O2. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood and body electronics per stress test requirements, including temperature cycling and HTRB. |
| Integrated bias network | R1 = 4.7 kΩ and R2 = 10 kΩ per transistor eliminate four external resistors, reducing BOM count and placement cost. |
| Dual complementary topology | NPN/PNP pairing enables true push-pull output without external level-shifting, simplifying interface to 3.3 V/5 V logic families. |
| Low saturation voltage | VCE(sat) ≤ 100 mV at IC = 10 mA ensures minimal power loss and clean logic-level outputs in switching applications. |
| Small-outline packaging | SOT363-3 (SC-88) footprint occupies < 3 mm² area, supporting high-density routing in infotainment and ADAS sensor modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMH18 | NPN/NPN configuration instead of NPN/PNP; identical R1/R2 values and package. | Suitable only where dual low-side switching is required; cannot provide complementary output polarity. | Select when driving two independent sinking loads from same logic source. |
| PUMB18 | PNP/PNP configuration; same bias resistor values and thermal specs as PUMD18. | Applicable for dual sourcing applications but lacks NPN complement for push-pull operation. | Choose for redundant high-side control or fail-safe sourcing in safety-critical nodes. |
Compared with PUMH18 and PUMB18, the PUMD18 uniquely provides matched NPN/PNP characteristics in one package, enabling true complementary output stages without inter-device timing mismatch or layout asymmetry.

FAQ
What is the maximum operating junction temperature for PUMD18?
The absolute maximum junction temperature (Tj) is 150 °C, validated per AEC-Q101 stress testing. Derating begins above 25 °C ambient, with total device power dissipation limited to 300 mW at Tamb ≤ 25 °C on standard FR4 PCB. Thermal resistance from junction to ambient is 417 K/W in free air.
Can PUMD18 replace two separate BC847/BC857 transistors in a push-pull circuit?
Yes - PUMD18 replaces one BC847 (NPN) and one BC857 (PNP) plus four external bias resistors. Its integrated R1/R2 network delivers equivalent biasing with tighter matching, reduced parasitic inductance, and guaranteed thermal coupling between complementary devices.
Is the pinout compatible with other SOT363-3 RETs like PUMH18?
Yes - all Nexperia SOT363-3 RETs share identical mechanical pinout and footprint. However, internal transistor polarity differs: PUMD18 has NPN/PNP, while PUMH18 is NPN/NPN. Swapping requires verifying signal polarity and load connection topology.
Does PUMD18 support 1.8 V logic-level input drive?
No - VI(on) is specified at 1.5 V (typ) for TR1 and −1.5 V (typ) for TR2, meaning reliable turn-on requires ≥2.5 V input for NPN and ≤−2.5 V for PNP. For 1.8 V systems, use logic-level shifters or higher-gain RET variants like PBSS4041.
