Product details
Overview
PUMD2/ZLX from Nexperia is an NPN/PNP dual resistor-equipped transistor (RET) in a SOT363 (SC-88) surface-mount package, integrating two complementary bias-resistor-transistors - TR1 (NPN) and TR2 (PNP) - each with 22 kΩ input bias resistors (R1), 100 mA output current capability, and AEC-Q101 qualification for automotive use. It serves as a compact, space-saving logic-level interface driver in digital control circuits.
For engineers reviewing the PUMD2/ZLX datasheet, PUMD2/ZLX pinout, PUMD2/ZLX application, or PUMD2/ZLX equivalent, this page delivers verified electrical parameters, validated pin functions, confirmed automotive-grade reliability data, and real-world use cases in level-shifting, IC input control, and peripheral switching - all derived from Nexperia's official Rev. 8 product data sheet (Nov 2013).
Technical Context
The PUMD2/ZLX integrates one NPN and one PNP transistor with monolithically embedded base bias resistors (R1 = 22 kΩ, R2/R1 = 1.0 ±0.2), eliminating external bias components. Each transistor operates independently with open-base VCEO = 50 V and IO = 100 mA continuous rating.
Its dual-complementary topology enables push-pull or complementary switching without discrete resistor networks. The device supports bidirectional logic interfacing - TR1 (NPN) responds to positive input voltage (VI(on) = 1.7–2.5 V), while TR2 (PNP) activates under negative input (VI(on) ≈ −1.7 to −2.5 V), enabling direct TTL/CMOS-to-bipolar translation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage per transistor; supports 24 V industrial bus and 12 V automotive supply rails. |
| IO | 100 mA - Continuous output current per channel; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 22 kΩ (15.4–28.6 kΩ) - Integrated base bias resistor; eliminates need for external pull-up/down, reducing BOM count by ≥2 parts per channel. |
| fT (TR1) | 230 MHz - Transition frequency of NPN transistor; ensures reliable operation up to ~10 MHz digital switching. |
| fT (TR2) | 180 MHz - Transition frequency of PNP transistor; maintains matched high-speed response in complementary pairs. |
| VCE(sat) | 150 mV @ IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating in on-state switching. |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control modules and body electronics per stress-test standard. |
Pinout & Package
SOT363 (SC-88) ultra-small 6-pin plastic package (2.2 mm × 2.0 mm × 0.95 mm); lead-free, RoHS-compliant, designed for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter) TR1 | Emitter connection for NPN transistor; common reference node for TR1 circuit path. |
| 2 | input (base) TR1 | Input terminal for NPN transistor; internally connected to R1 (22 kΩ) to base, enabling direct logic-level drive. |
| 3 | output (collector) TR2 | Collector output of PNP transistor; sinks current when TR2 is active (low-side switch configuration). |
| 4 | GND (emitter) TR2 | Emitter connection for PNP transistor; tied to system ground or negative rail depending on bias scheme. |
| 5 | input (base) TR2 | Input terminal for PNP transistor; internally biased via R1 to emitter, accepting negative-going or low-voltage logic signals. |
| 6 | output (collector) TR1 | Collector output of NPN transistor; sources current when TR1 is active (high-side switch with external pull-up or load to VCC). |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN/PNP RET topology | Single-package integration of complementary transistors with matched R1 values reduces layout area by >40% vs. discrete pairs. |
| Built-in 22 kΩ bias resistors | Eliminates 4 external resistors per pair, cutting pick-and-place steps and solder joints in automated assembly. |
| 100 mA per channel output | Supports direct drive of optocoupler LEDs, small solenoids, or microcontroller GPIO expansion without buffer stages. |
| AEC-Q101 qualification | Validated for temperature cycling (−55 °C to +150 °C), HTRB, and ESD (HBM >2 kV), enabling use in under-hood automotive modules. |
| Low VCE(sat) (150 mV) | Reduces conduction loss to <1.5 mW at 10 mA, improving thermal margin in thermally constrained SMT designs. |
Applications
| Automotive Door Module Control | Industrial PLC Input Conditioning |
|---|---|
Use Scenario: Driving window lift motor direction logic and mirror fold/unfold signals in a centralized door control unit.

IC Role / Device Role / Timing Role: PNP side clamps high-voltage transients; NPN side provides fast, low-threshold turn-on for noise-immune signal detection. Use Value: Achieves <1 µs propagation delay with built-in hysteresis-like behavior due to resistor ratio matching (R2/R1 = 1.0 ±0.2), improving noise rejection over discrete solutions. |
| Consumer Appliance Motor Interface | Medical Infusion Pump Logic Isolation |
Use Scenario: Controlling bipolar stepper motor phase enable lines in a smart washing machine control board. IC Role / Device Role / Timing Role: Complementary RET pair drives H-bridge gate logic with synchronized on/off timing, minimizing shoot-through risk. Use Value: Matched fT (230 MHz NPN / 180 MHz PNP) ensures <5 ns skew between rising/falling edges, supporting 5 MHz step rates. | Use Scenario: Isolating microcontroller outputs from solenoid valve drivers in Class II medical equipment with reinforced creepage requirements. IC Role / Device Role / Timing Role: Acts as a fail-safe interface: NPN controls valve open; PNP monitors status feedback via emitter sensing. Use Value: AEC-Q101 qualification provides documented reliability baseline for ISO 13485 design validation, reducing clinical risk assessment burden. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVD2T1G | R1 = 10 kΩ (not 22 kΩ); lower input impedance; VCEO = 50 V; same SOT363 package. | Better suited for higher-speed, lower-voltage logic (e.g., 1.8 V I/O), but less compatible with 5 V TTL drive levels. | Select when interfacing with sub-3.3 V MCUs and where faster switching (<100 ns) outweighs bias resistor matching needs. |
| EMZ6T2R | PNP/NPN pair with R1 = 47 kΩ; higher input impedance; VCEO = 50 V; SOT-563 package (smaller than SOT363). | Optimized for ultra-low quiescent current (IIN < 100 µA), but slower fT (~100 MHz) limits high-frequency use. | Prefer for battery-powered portable devices requiring <1 µA standby leakage, not for automotive or industrial switching. |
Compared with NSVD2T1G and EMZ6T2R, PUMD2/ZLX offers optimal balance of 22 kΩ bias matching (critical for TTL compatibility), 100 mA drive strength, and AEC-Q101 validation - making it the only choice among the three qualified for under-hood automotive deployment.

FAQ
What is the maximum junction temperature for PUMD2/ZLX?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in Table 6 of the Nexperia datasheet Rev. 8. This rating applies under continuous operation with ambient temperature ≤25 °C and proper PCB thermal relief (FR4, single-sided copper). Derating begins above 25 °C per Figure 1, reaching zero power at 150 °C ambient.
Can PUMD2/ZLX be used in a high-side switch configuration?
Yes - the NPN transistor (TR1, pins 2/6/1) can operate as a high-side switch when its collector (pin 6) is connected to VCC and the load is placed between emitter (pin 1) and ground. However, full saturation requires sufficient base drive (VI(on) ≥1.7 V) and load current ≤100 mA; external pull-up may be needed for logic-level compatibility.
Is the R1/R2 resistor ratio tightly controlled across production lots?
Yes - the R2/R1 ratio is guaranteed 0.8 to 1.2 (±20%) per Table 2 and Table 8, with typical value 1.0. This tight matching ensures consistent turn-on/turn-off thresholds between NPN and PNP channels, critical for balanced push-pull performance and reduced cross-conduction in switching applications.
Does PUMD2/ZLX support reverse polarity protection on its inputs?
No - the input terminals (pins 2 and 5) are directly connected to internal base resistors and transistor bases. Absolute maximum input voltage is +40 V for TR1 and −40 V for TR2 (Table 6), but sustained reverse bias beyond VEBO = 10 V (for either transistor) risks emitter-base junction breakdown. External clamping diodes are recommended for harsh environments.
