Diodes Incorporated DZT2907A-13

Overview

DZT2907A-13 from Diodes Incorporated is a 60V PNP small-signal transistor in SOT223 package, rated for -600mA continuous collector current and -60V V_CEO, with h_FE ≥100 at I_C = -150mA and V_CE = -10V, used in medium-power switching and amplification stages of industrial power supplies and motor drivers.

For engineers reviewing the DZT2907A-13 datasheet, DZT2907A-13 pinout, DZT2907A-13 application, or DZT2907A-13 equivalent, key selection criteria include verified V_CEO rating, SOT223 thermal performance (R_θJA = 150°C/W), DC current gain consistency across I_C = -100µA to -500mA, and complementary pairing with DZT2222A for push-pull designs.

Technical Context

This PNP bipolar junction transistor employs epitaxial planar die construction for stable gain and low leakage, supporting switching speeds with t_on ≤ 45ns and t_off ≤ 100ns under defined bias conditions. Its safe operating area (SOA) is characterized up to -60V and -800mA peak current, with derating starting above +25°C at 6.66mW/°C.

The device operates across -55°C to +150°C junction temperature range and features -5V V_EBO, -0.4V V_CE(sat) at I_C = -150mA/I_B = -15mA, and f_T = 200MHz - enabling use in medium-frequency analog amplification and hard-switched DC-DC control circuits.

FAQ

What is the maximum allowable junction temperature for DZT2907A-13?

The DZT2907A-13 has an absolute maximum junction temperature of +150°C and a storage temperature range of -55°C to +150°C. Operation at or near this limit requires strict adherence to the derating curve: power dissipation must decrease by 6.66mW per °C above +25°C ambient, based on minimum recommended pad layout on FR4.

Is DZT2907A-13 pin-compatible with the older DZT2907A-7?

Yes - both DZT2907A-13 and DZT2907A-7 use identical SOT223 packaging, pin assignment (Emitter-Base-Collector-Tab), and mechanical dimensions. The "-13" suffix denotes 2,500-unit tape-and-reel packaging (13-inch reel, 12mm tape width), while "-7" indicates 1,000-unit reels; electrical and thermal specs are identical.

Can DZT2907A-13 replace a TO-92 PNP transistor like MPSA92 in existing designs?

No direct drop-in replacement: DZT2907A-13 uses SOT223 (4-pin, thermal tab), whereas MPSA92 is TO-92 (3-pin, no thermal pad). Layout, thermal management, and soldering process differ significantly. Electrical parameters overlap (e.g., V_CEO = -300V for MPSA92 vs. -60V here), so functional substitution requires circuit revalidation - especially for voltage margin and thermal performance.

Does DZT2907A-13 support automotive qualification out of the box?

DZT2907A-13 is manufactured in IATF 16949-certified facilities and meets AEC-Q101 stress test requirements. However, formal PPAP submission and automotive qualification require customer-specific change control documentation and part-level testing - contact Diodes or Aetrix for AEC-Q101 certified lot traceability and PPAP support packages.
