Product details

Overview

D45VH10 from onsemi is a PNP silicon power transistor designed for high-speed switching in switching regulators and high-frequency inverters, with V_CEO = 80 V, I_C = 15 A continuous, V_CE(sat) ≤ 1.0 V at I_C = 8 A / I_B = 0.8 A, and R_JC = 1.5 °C/W - deployed as a high-current driver in industrial DC-DC converters.

For engineers reviewing the D45VH10 datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed V_CE(sat) at 100 °C, complementary pairing with D44VH10, TO-220 thermal performance, and safe operating area (SOA) compliance up to 100 V/15 A pulses.

Technical Context

The D45VH10 operates as a medium-power PNP bipolar junction transistor optimized for hard-switching topologies. Its SOA is defined up to 100 V with pulse width ≤6 ms and duty cycle ≤50%, and it sustains V_CEV = 100 V under open-base conditions.

It delivers f_T = 50 MHz at I_C = 0.1 A, V_CE = 10 V, and exhibits C_ob = 275 pF at V_CB = 10 V - enabling use in >100 kHz switching circuits where charge storage and turn-off delay must be minimized.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 Vdc - maximum collector-emitter voltage before breakdown under open-base condition; defines upper rail limit in linear or switching regulator designs.
I_C (continuous)	15 Adc - continuous collector current rating at T_C = 25 °C; derates linearly above 25 °C per 0.67 W/°C slope.
V_CE(sat)	≤1.0 V at I_C = 8 A, I_B = 0.8 A - low saturation voltage minimizes conduction loss in high-current switching paths.
R_JC	1.5 °C/W - junction-to-case thermal resistance enables direct heatsink mounting with predictable temperature rise under 83 W dissipation.
f_T	50 MHz - current gain bandwidth product confirms suitability for high-frequency switching up to ~5–10 MHz practical operation.
C_ob	275 pF at V_CB = 10 V - output capacitance impacts switching speed and EMI in hard-switched topologies; higher than NPN counterpart D44VH10 (120 pF).
h_FE	20 min at I_C = 4 A, V_CE = 1 V - DC current gain sufficient for base-driven switching without excessive drive power overhead.

Pinout & Package

Package: TO-220 (Case 221A, Style 1), 3-terminal variant with dual collector pins (pins 2 and 4), base on pin 1, emitter on pin 3 - thermally optimized for vertical heatsink mounting with insulated hardware.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input for bipolar conduction; requires ≥0.8 A peak base drive to saturate at 8 A collector current.
2 & 4	Collector	High-current output node; electrically common; both pins must be connected to main power rail or heatsink for thermal and current sharing.
3	Emiter	Reference terminal for PNP operation; connects to positive supply rail in high-side switch configurations.

Key Features

Feature	Design Value
Fast switching	ts = 700 ns, tf = 90 ns - enables efficient operation in 50–200 kHz SMPS with minimal switching loss.
Low V_CE(sat) at elevated temperature	V_CE(sat) specified at T_C = 100 °C - ensures stable conduction loss in thermally constrained enclosures.
Complementary pairing	Matched with D44VH10 (NPN) in V_CEO, I_C, and SOA - simplifies push-pull, H-bridge, and totem-pole driver design.
Pb-Free & RoHS compliant	G-suffix package - meets global environmental regulations without compromising solderability or thermal performance.
Robust SOA	Rated for 100 V × 15 A pulses (≤6 ms, ≤50% duty) - supports surge-tolerant motor drive and inverter applications.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD45H11T4G	V_CEO = 100 V, I_C = 8 A, R_JC = 3.0 °C/W - lower current rating and higher thermal resistance.	Not suitable for 15 A continuous loads; limited to <10 A average current in same PCB layout.	Select when higher V_CEO margin is prioritized over current capacity and thermal performance.
BDX54C	V_CEO = 100 V, I_C = 12 A, f_T = 3 MHz - significantly slower switching and lower bandwidth.	Restricted to ≤20 kHz operation; unsuitable for modern high-frequency SMPS or inverters.	Choose only for legacy linear amplifier or low-speed relay driver designs where cost outweighs speed.

Compared with MJD45H11T4G and BDX54C, the D45VH10 uniquely balances 15 A current handling, 80 V rating, 50 MHz f_T, and 1.5 °C/W thermal resistance - making it the only option among the three qualified for thermally demanding, high-frequency switching regulator output stages.

FAQ

What is the maximum continuous collector current rating for the D45VH10?

The D45VH10 has a maximum continuous collector current (I_C) of 15 A at case temperature (T_C) = 25 °C. This rating decreases linearly above 25 °C at 0.67 W/°C due to its 83 W total power dissipation limit and 1.5 °C/W junction-to-case thermal resistance. At T_C = 100 °C, the usable I_C drops to approximately 10 A to maintain safe junction temperature.

Does the D45VH10 have a complementary NPN counterpart, and how are they matched?

Yes, the D45VH10 (PNP) is explicitly paired with the D44VH10 (NPN) as a complementary silicon power transistor set. They share identical V_CEO = 80 V, I_C = 15 A, R_JC = 1.5 °C/W, and SOA ratings - enabling symmetrical design in push-pull, H-bridge, and totem-pole configurations without derating either device.

What is the typical V_CE(sat) of the D45VH10 under standard switching conditions?

The D45VH10 exhibits V_CE(sat) ≤ 1.0 V when operated at I_C = 8.0 A and I_B = 0.8 A, per the datasheet's Figure 8 and Electrical Characteristics table. This value is guaranteed at T_C = 25 °C and remains ≤1.5 V at T_C = 100 °C - ensuring predictable conduction loss across industrial temperature ranges.

Can the D45VH10 be used in surface-mount designs?

No, the D45VH10 is exclusively offered in the through-hole TO-220 (Case 221A) package, as confirmed by the Ordering Information table and mechanical drawings. It lacks an SMT variant; any surface-mount implementation would require an adapter board or alternative part such as the SOT-223 or DPAK versions in onsemi's portfolio - none of which share identical electrical specs with the D45VH10.

Is the D45VH10 RoHS compliant and lead-free?

Yes, the D45VH10G variant is explicitly marked as Pb-Free and RoHS compliant in the datasheet's Ordering Information and Features sections. The "G" suffix denotes the lead-free package, and the device meets EU RoHS Directive 2011/65/EU requirements without exemptions - verified via onsemi's official compliance documentation and material declarations.
