Product details

Overview

PZT2907A,135 from Nexperia is a PNP bipolar junction transistor (BJT) designed for medium-power switching and linear amplification in industrial control and power management circuits. It delivers −600 mA DC collector current, −60 V collector-emitter voltage rating, and exhibits DC current gain (h_FE) of 100–300 at −150 mA, housed in a thermally enhanced SOT223 surface-mount package with dual collector terminals.

For engineers reviewing the PZT2907A,135 datasheet, PZT2907A,135 pinout, PZT2907A,135 application, or PZT2907A,135 equivalent, key selection criteria include verified PNP switching capability, thermal resistance (R_{th j-a} = 106 K/W), saturation voltage (V_CEsat ≤ −1.6 V @ −500 mA), and compatibility with SOT223 PCB layout standards.

Technical Context

This device operates as a general-purpose PNP BJT with fixed-base current-controlled conduction. Its design supports fast switching (t_off = 365 ns, t_s = 300 ns) and stable DC amplification across −65 °C to +150 °C ambient range, enabled by low emitter capacitance (C_e = 30 pF) and transition frequency f_T = 200 MHz.

Thermal performance is optimized via the SOT223's exposed collector pad (1 cm² copper area), delivering R_{th j-s} = 25 K/W to soldering point and enabling 1.15 W total power dissipation at T_amb ≤ 25 °C - critical for compact power-stage designs without forced cooling.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V: Maximum safe collector-emitter voltage before breakdown in open-base configuration.
I_C (DC)	−600 mA: Continuous collector current handling capacity under steady-state operation.
h_FE	100–300 @ −150 mA: Confirmed DC current gain range enabling predictable base drive sizing.
V_CEsat	≤ −1.6 V @ −500 mA/−50 mA: Low saturation voltage ensures minimal conduction loss in high-current switches.
R_{th j-a}	106 K/W: Thermal resistance from junction to ambient on standard single-sided 1 cm² copper PCB.
f_T	200 MHz: Transition frequency confirming suitability for audio-frequency and low-MHz switching applications.
t_off	365 ns: Total turn-off time (10%–90%) supporting PWM operation up to ~300 kHz.

Pinout & Package

SOT223 plastic surface-mount package with 4 leads: thermally optimized for power dissipation via large exposed collector pad; pin 1 = base, pins 2 & 4 = collector (internally connected), pin 3 = emitter.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control terminal; requires negative bias relative to emitter to forward-bias base-emitter junction.
2, 4	Collector	Power output terminal; electrically common; connects directly to PCB copper pour for heat sinking.
3	Emiter	Reference terminal; typically tied to higher potential (e.g., V_CC) in PNP switch configurations.

Key Features

Feature	Design Value
High DC current capability	−600 mA continuous collector current enables direct driving of relays, LEDs, and small solenoids.
Low V_CEsat at high current	−1.6 V max @ −500 mA reduces power loss and self-heating in saturated switching mode.
Thermally robust SOT223	Exposed collector pad and 1.15 W power rating support operation without heatsinks in space-constrained layouts.
Fast switching performance	365 ns turn-off time allows reliable use in 200–300 kHz PWM circuits with minimal dead-time overhead.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP switching transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBT2907A	SOT-23 package; lower I_C (−600 mA peak, −200 mA continuous); R_{th j-a} = 300 K/W.	Limited to low-power signal switching; unsuitable for >200 mA sustained loads or thermal cycling.	Select when board space is critical and load current remains below 150 mA.
ZTX753	SOT-89 package; higher V_CEO (−100 V); h_FE = 100–250 @ −500 mA; R_{th j-a} = 70 K/W.	Better suited for high-voltage industrial sensors and flyback clamp circuits requiring >−60 V margin.	Select when system flyback transients exceed −60 V or thermal budget demands <80 K/W.

Compared with MMBT2907A and ZTX753, PZT2907A,135 uniquely balances medium-current capability (−600 mA), thermal performance (106 K/W), and cost-effective SOT223 manufacturability - making it optimal for industrial power interfaces where reliability and thermal headroom are prioritized over ultra-compact footprint or extreme voltage rating.

FAQ

What is the maximum continuous collector current for PZT2907A,135?

The maximum continuous DC collector current is −600 mA at T_amb ≤ 25 °C, as specified in the Absolute Maximum Ratings table. Derating applies above 25 °C ambient per the thermal resistance curve; at 70 °C ambient, usable current drops to approximately −400 mA to maintain T_j ≤ 150 °C.

Does PZT2907A,135 have a built-in base-emitter resistor?

No, PZT2907A,135 is a standard discrete PNP BJT without integrated resistors. It requires an external base current-limiting resistor to establish proper bias conditions. The device has no internal pull-up, pull-down, or current-limiting elements - all base drive must be externally controlled.

Can PZT2907A,135 replace NXP's original PZT2907A without design changes?

Yes - PZT2907A,135 is the direct Nexperia continuation of the legacy NXP PZT2907A. Electrical specifications, pinout, package dimensions, and thermal characteristics are identical; only branding and copyright attribution changed per Nexperia's 2017 corporate transition. No schematic or layout modifications are required.

What is the recommended PCB layout for optimal thermal performance?

Mount PZT2907A,135 on a single-sided 1 cm² copper pad connected to pins 2 and 4 (collector). Use thermal vias under the pad if multilayer boards are used. Keep traces to base (pin 1) and emitter (pin 3) short and wide to minimize parasitic inductance during switching. Avoid placing heat-sensitive components within 3 mm of the collector pad edge.
