onsemi NSVPZTA92T3G

Overview

NSVPZTA92T3G from onsemi is a PNP silicon high-voltage transistor rated for −300 V_CEO, −500 mA collector current, and 1.5 W power dissipation in SOT-223 package; it operates up to +150 °C junction temperature and serves as a robust switching element in automotive ignition drivers and industrial HV DC-DC bias circuits.

For engineers reviewing the NSVPZTA92T3G datasheet, pinout, applications, or equivalent options, key selection criteria include its −300 V breakdown rating, AEC-Q101 qualification, SOT-223 thermal performance (R_JA = 83.3 °C/W), h_FE ≥ 25 at −1 mA, and f_T = 50 MHz bandwidth capability.

Technical Context

This PNP bipolar junction transistor is designed for high-voltage linear and switching applications where stable gain and low leakage are critical. It features V_(BR)CEO = −300 V, I_CBO ≤ −0.25 A, and V_BE(sat) = −0.9 V at −20 mA/−2 mA drive - enabling reliable turn-on in high-side switch configurations with minimal base drive loss.

Its f_T = 50 MHz and C_cb = 6.0 pF support moderate-speed switching in flyback snubbers and relay drivers. The device's thermal resistance (R_JA = 83.3 °C/W on FR-4) and 150 °C max junction temperature allow operation in thermally constrained automotive under-hood environments without forced cooling.

FAQ

What is the maximum collector-emitter voltage rating for NSVPZTA92T3G?

The NSVPZTA92T3G has a guaranteed minimum V_(BR)CEO of −300 V at I_C = −1.0 mA and T_A = 25 °C. This rating is validated per JEDEC JESD22-A114 and maintained across the full operating temperature range (−55 °C to +150 °C), making NSVPZTA92T3G suitable for circuits where transient overvoltages exceed 250 V.

Is NSVPZTA92T3G qualified for automotive applications?

Yes, NSVPZTA92T3G is AEC-Q101 qualified and PPAP capable. The "NSV" prefix explicitly denotes compliance with automotive-specific site controls and change management requirements. Its qualification includes HTOL, temperature cycling, and HTRB testing - confirming suitability for engine control units, body controllers, and lighting modules.

What package type does NSVPZTA92T3G use and how is thermal performance characterized?

NSVPZTA92T3G uses the SOT-223 (Case 318E) surface-mount package with pins 2 and 4 internally connected to the collector and exposed thermal pad. Its thermal resistance is R_JA = 83.3 °C/W when mounted on a 1.575 in × 1.575 in FR-4 board with 0.93 in² copper area - a value measured per JESD51-2 and used for derating calculations in NSVPZTA92T3G thermal design.

Does NSVPZTA92T3G have a complementary NPN device?

Yes, NSVPZTA92T3G is explicitly designed as the PNP complement to the PZTA42T1G NPN transistor. Both share identical SOT-223 packaging, voltage ratings (V_CEO = +300 V for PZTA42T1G), and AEC-Q101 qualification - enabling matched pair usage in push-pull, differential, or totem-pole output stages requiring symmetrical HV switching.

What is the DC current gain (h_FE) range for NSVPZTA92T3G under standard conditions?

At I_C = −1.0 mA, V_CE = −10 V, and T_A = 25 °C, NSVPZTA92T3G guarantees h_FE ≥ 25. At I_C = −10 mA and −30 mA under the same conditions, h_FE is ≥ 40. These values are specified in the official onsemi datasheet PZTA92T1/D Rev. 12 and confirmed across production lots for NSVPZTA92T3G.
