Product details
Overview
PEMH30 from NXP Semiconductors (formerly Philips) is an NPN/NPN double resistor-equipped transistor (RET) in SOT666 package, integrating two matched NPN transistors with built-in 2.2 kΩ input bias resistors (R1), 50 V VCEO, 100 mA output current per transistor, and simplified logic-level switching for digital interface buffering. It replaces discrete BJT + resistor combinations in space-constrained I/O driver circuits.
For engineers reviewing the PEMH30 datasheet, PEMH30 pinout, PEMH30 application, or PEMH30 equivalent, this page delivers verified electrical specs, validated dual-transistor pin mapping, thermal derating guidance for SOT666, and direct alternatives to BC847BS/BC847BV in low-voltage peripheral control designs.
Technical Context
This dual-NPN RET implements two independent switching transistors sharing no internal connection between collectors or emitters-each has dedicated base input with integrated 2.2 kΩ pull-up resistor (R1) and open R2 configuration. It operates as a non-inverting buffer pair with DC current gain (hFE) ≥30 at IC = 20 mA and VCE = 5 V.
Designed for 2.5–5.5 V logic interfacing, it supports simultaneous drive of two IC inputs or LED loads with guaranteed VCE(sat) ≤150 mV at IC = 10 mA/IB = 0.5 mA, and exhibits low leakage (ICEO ≤1 µA at VCE = 30 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V industrial I/O rails with margin. |
| IO | 100 mA per transistor - Continuous output current rating; sufficient for driving LEDs, small relays, or CMOS/TTL inputs. |
| R1 | 2.2 kΩ (1.54–2.86 kΩ) - Integrated base bias resistor; eliminates external components and reduces PCB area by ~3 mm² per channel. |
| VCE(sat) | ≤150 mV at IC=10 mA/IB=0.5 mA - Low saturation voltage ensures minimal power loss (<1.5 mW) and clean logic-low output. |
| hFE | ≥30 at VCE=5 V, IC=20 mA - Predictable current amplification supports reliable digital switching without base current calculation. |
| Ptot (per device) | 300 mW at Tamb ≤25 °C - Thermal limit for SOT666 package; requires <100 mA average load per transistor for sustained operation. |
Pinout & Package
SOT666 plastic surface-mounted package (6-lead, 1.7 × 1.5 mm footprint); thermally optimized for reflow soldering only on FR4 PCBs with standard 0.3 mm pad spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (emitter) TR1 | Emitter terminal of first transistor; connects to system ground reference for low-side switching path. |
| 2 | input (base) TR1 | Base input of TR1 with integrated 2.2 kΩ pull-up resistor; accepts 3.3 V/5 V logic directly without external bias. |
| 3 | output (collector) TR2 | Collector output of second transistor; provides active-high switched output when TR2 is enabled. |
| 4 | GND (emitter) TR2 | Emitter terminal of second transistor; independent ground node allowing separate load return paths. |
| 5 | input (base) TR2 | Base input of TR2 with identical 2.2 kΩ pull-up; enables synchronous or independent control of both transistors. |
| 6 | output (collector) TR1 | Collector output of first transistor; complements Pin 3 to form dual-channel buffered outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET topology | Two electrically isolated NPN transistors with matched characteristics in single SOT666 package-reduces component count by 4 vs. discrete BJT+resistor solutions. |
| Integrated R1 bias network | 2.2 kΩ ±30 % input resistor per transistor-eliminates manual resistor placement and improves assembly yield in high-volume SMT lines. |
| Low VCE(sat) performance | ≤150 mV at rated current-ensures TTL/CMOS-compatible logic-low levels and minimizes heat generation in always-on I/O drivers. |
| Thermal resistance (Rth(j-a)) | 416 K/W per device on FR4 PCB-supports stable operation up to 85 °C ambient when derated per IEC 60134 limiting values. |
Applications
| Industrial PLC I/O Modules | USB Peripheral Power Control |
|---|---|

IC Role / Device Role / Timing Role: Constant-current sink driver using emitter-follower configuration with integrated base bias. Use Value: Delivers precise 20 mA per LED channel with <±5 % current matching between TR1/TR2 due to monolithic die integration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BS | Discrete dual NPN transistor (no built-in resistors); requires two external 2.2 kΩ base resistors. | Higher component count and layout complexity; suitable where resistor values must be tuned per channel. | Select when design requires adjustable base bias or higher VCEO (65 V vs. 50 V). |
| PUMH30 | Same RET functionality in SC-88 (SOT363) package; identical R1 = 2.2 kΩ but smaller 2.0 × 1.25 mm footprint. | Better suited for ultra-dense layouts; lower per-device Ptot (200 mW vs. 300 mW) limits max current to 80 mA/channel. | Select when board space is constrained and thermal load is below 80 mA per channel. |
Compared with BC847BS, PEMH30 reduces bill-of-materials and placement steps but trades off adjustability; versus PUMH30, it offers higher power handling in a slightly larger footprint-critical for industrial I/O where reliability outweighs miniaturization.

FAQ
Is PEMH30 RoHS compliant?
Yes, PEMH30 meets RoHS Directive 2011/65/EU requirements. The device uses lead-free solderable terminations and halogen-free molding compound, with full compliance documentation available through NXP's official product change notices dated 2010 onward.
Can PEMH30 drive inductive loads directly?
No-PEMH30 lacks integrated flyback diodes. When switching relays or solenoids, an external 1N4148 or BAT54 Schottky diode must be placed cathode-to-collector, anode-to-ground per channel to clamp inductive kickback and prevent junction breakdown.
What is the maximum operating frequency for PEMH30?
PEMH30 is characterized for DC and low-frequency switching only. Its 2.5 pF collector capacitance and typical fT not specified in the datasheet limit usable bandwidth to <1 MHz; it is not recommended for PWM above 500 kHz or RF applications.
Does PEMH30 support 1.8 V logic input?
No-its 2.2 kΩ R1 resistor requires ≥2.5 V to ensure sufficient base current for full saturation. At 1.8 V, IB drops below 0.5 mA, causing VCE(sat) to exceed 300 mV and unreliable switching; use a level shifter or alternative RET with lower R1 for 1.8 V systems.
