Product details
Overview
PUMD20/ZLX 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 IO, with integrated 2.2 kΩ input bias resistors (R1 = R2) per transistor, used for low-current digital signal switching and IC input control in automotive body electronics.
For engineers reviewing the PUMD20/ZLX datasheet, PUMD20/ZLX pinout, PUMD20/ZLX application, or PUMD20/ZLX equivalent, this device serves as a space-optimized, component-count-reducing replacement for discrete NPN+PNP pairs in level-shifting, bus buffering, and logic interface circuits where built-in biasing eliminates external resistors.
Technical Context
The PUMD20/ZLX integrates two complementary bipolar transistors - TR1 (NPN) and TR2 (PNP) - each with monolithically embedded base bias resistors (R1 = 2.2 kΩ, R2/R1 = 1.0), enabling direct TTL/CMOS-level drive without external bias networks. It operates across −40 °C to +150 °C ambient temperature with junction-limited thermal performance.
Its dual-transistor topology supports push-pull output configurations and bidirectional signal conditioning, while the matched R1/R2 ratio ensures consistent turn-on/off thresholds between NPN and PNP sections under varying temperature conditions (0.8–1.2 over −40 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current per transistor; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 2.2 kΩ ±30% - Integrated base-input resistor; eliminates need for external pull-up/down components in digital interfaces. |
| hFE | 30 min at IC = 20 mA, VCE = 5 V - Ensures reliable saturation with modest base drive, reducing MCU GPIO loading. |
| VCE(sat) | 150 mV max at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching applications. |
| Ptot (per device) | 300 mW at Tamb ≤ 25 °C on FR4 PCB - Defines maximum allowable dissipation before thermal derating applies. |
Pinout & Package
SOT363-3 (TSSOP6) plastic surface-mounted package: 2.2 mm × 1.35 mm footprint, 0.65 mm pitch, 0.95 mm max height, optimized for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1 (NPN); common reference node for first transistor section. |
| 2 | I1 | Base input for TR1 (NPN); driven directly by logic-level signals without external resistor. |
| 3 | O2 | Collector output for TR2 (PNP); provides active-low switching capability. |
| 4 | GND2 | Emiter connection for TR2 (PNP); independent ground path for second transistor section. |
| 5 | I2 | Base input for TR2 (PNP); accepts negative-logic or inverted drive signals. |
| 6 | O1 | Collector output for TR1 (NPN); provides active-high switching capability. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors (R1 = R2 = 2.2 kΩ) | Reduces bill-of-materials count by eliminating two external resistors per channel and simplifies layout routing. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards. |
| Matched NPN/PNP pair | Enables symmetrical push-pull output stages with consistent VI(on)/VI(off) thresholds across temperature. |
| Low VCE(sat) (150 mV max) | Minimizes conduction losses in battery-powered or thermally constrained modules such as door modules and seat controllers. |
| Small SOT363-3 footprint | Occupies 2.97 mm² board area - 60% smaller than SO-8 equivalents - supporting miniaturized ECUs and sensor nodes. |
Applications
| Automotive Door Module Interface | Industrial PLC Input Buffer |
|---|---|
|
Use Scenario: Driving window lift motor direction control signals and mirror adjustment switches in vehicle door modules. IC Role / Device Role / Timing Role: Dual RET acts as level translator and current amplifier between 3.3 V microcontroller GPIOs and 12 V load-side logic.

| USB-C Port Power Switch Control | Smart Lighting Dimmer Interface |
|
Use Scenario: Enabling/disabling VBUS path control MOSFETs and CC line termination in USB-C receptacle circuits. IC Role / Device Role / Timing Role: Acts as dual-polarity gate driver with fast turn-on (ton < 50 ns typical) and controlled edge rates. Use Value: Supports USB PD 3.0 compliance by ensuring <100 ns response time during port role swap events. |
Use Scenario: Interfacing DALI-2 bus signals to microcontroller UART peripherals in LED driver modules. IC Role / Device Role / Timing Role: Converts bidirectional 16 V DALI differential signals to unidirectional 3.3 V logic levels using NPN/PNP complementarity. Use Value: Maintains DALI timing integrity (bit period ±5%) across −40 °C to +105 °C operating range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PUMH20 | NPN/NPN configuration only; identical R1/R2 values and SOT363-3 package. | Suitable for dual-sourcing in push-pull drivers requiring same-polarity outputs. | Select when both outputs must sink current (e.g., LED matrix column drivers). |
| PUMB20 | PNP/PNP configuration only; same bias resistor values and thermal specs. | Used where both outputs source current (e.g., high-side switch buffers). | Choose for applications needing active-high outputs without level inversion. |
Compared with PUMD20/ZLX, PUMH20 and PUMB20 lack complementary polarity - limiting their use in true push-pull or bidirectional signal conditioning - whereas PUMD20/ZLX's NPN/PNP pairing enables zero-crossing switching and reduced shoot-through risk in half-bridge pre-drivers.

FAQ
What is the maximum operating temperature for PUMD20/ZLX?
The PUMD20/ZLX has a specified junction temperature limit of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance from junction to ambient is 416 K/W (per device on FR4 PCB), allowing continuous operation at full rated current up to +105 °C ambient when mounted per standard footprint guidelines.
Can PUMD20/ZLX replace discrete NPN+PNP transistor pairs in existing designs?
Yes - PUMD20/ZLX is designed as a drop-in replacement for dual discrete transistors with external base resistors. Its pinout maps GND1/I1/O1 to TR1 and GND2/I2/O2 to TR2, preserving signal routing while removing four passive components. Layout changes are limited to footprint adaptation to SOT363-3.
Does PUMD20/ZLX support 5 V logic interfacing without level shifters?
Yes - VI(on) is 1.6 V typical and VI(off) is 0.5 V typical for TR1 (NPN), and symmetric thresholds apply to TR2 (PNP). This allows direct connection to 5 V TTL and 3.3 V CMOS outputs without additional translation circuitry, provided VCC does not exceed 50 V.
Is there any derating required for power dissipation at elevated temperatures?
Yes - the per-device Ptot rating drops linearly above 25 °C ambient, with full derating to zero at 150 °C. The published derating curve shows 200 mW available at +75 °C ambient, confirming suitability for under-hood automotive environments when airflow or copper pour is applied.
