Product details
Overview
DPBT8105-7 from Diodes Incorporated is a 1A PNP surface-mount transistor in SOT23 package, rated for -60V VCEO, -80V VCBO, and 600mW power dissipation at 25°C ambient. It delivers hFE = 100–300 at IC = -1mA to -1A, VCE(SAT) ≤ -0.6V at IC = -1A/IB = -100mA, and fT = 150MHz - used in automotive body control modules for load switching and medium-power amplification.
For engineers reviewing the DPBT8105-7 datasheet, DPBT8105-7 pinout, DPBT8105-7 application, or DPBT8105-7 equivalent, key selection criteria include its AEC-Q101 qualification, complementary pairing with DNBT8105, RoHS-compliant "Green" molding compound, and thermal resistance of 209°C/W on FR-4 PCB per AP02001 layout.
Technical Context
This PNP bipolar junction transistor uses epitaxial planar die construction for stable gain and low leakage. Its -60V VCEO and -80V VCBO support medium-voltage switching in 12V/24V automotive systems, while the 150MHz fT enables audio-frequency amplification and fast-switching PWM drive.
The device operates across -55°C to +150°C and meets AEC-Q101 stress-test requirements for high-reliability automotive use. Its SOT23 package with matte tin-plated copper leadframe ensures solderability per MIL-STD-202 Method 208 and moisture sensitivity Level 1 per J-STD-020D.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | -60V - supports switching loads up to 60V reverse bias in automotive battery-supplied circuits |
| IC (cont.) | -1A - handles continuous current for solenoid drivers, LED arrays, and relay coils |
| PD @ 25°C | 600mW - defines maximum steady-state power on standard FR-4 PCB with AP02001 pad layout |
| hFE | 100–300 - provides predictable current amplification across IC = -1mA to -1A at VCE = -5V |
| fT | 150MHz - enables stable small-signal amplification up to mid-VHF range |
| RθJA | 209°C/W - determines junction temperature rise under defined PCB thermal conditions |
| VBE(SAT) | -1.2V @ IC = -1A/IB = -100mA - sets base drive voltage requirement for full saturation |
Pinout & Package

Use Scenario: Switching 12V/24V solenoids and door-lock actuators in BCM modules. IC Role / Device Role / Timing Role: PNP high-side switch controlling ground-return loads via microcontroller GPIO. Use Value: -60V VCEO withstands load-dump transients; -0.6V VCE(SAT) minimizes power loss at 1A. | Use Scenario: Driving electromechanical relays in programmable logic controllers. IC Role / Device Role / Timing Role: Medium-power interface transistor isolating MCU outputs from inductive relay coils. Use Value: 150MHz fT ensures clean turn-off without oscillation; hFE ≥ 100 guarantees reliable drive with minimal base current. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBT4403 | -40V VCEO, -600mA IC, hFE = 100–300, same SOT23 package | Limited to lower-voltage 5–12V systems; insufficient for 24V load-dump immunity | Select when cost sensitivity outweighs voltage headroom and automotive qualification |
| ZTX753 | -100V VCEO, -1A IC, hFE = 100–250, SOT89 package | Larger thermal mass and higher RθJA; requires different PCB footprint and layout | Choose for higher voltage margin where board space allows SOT89 mounting |
Compared with MMBT4403 and ZTX753, DPBT8105-7 uniquely balances AEC-Q101 compliance, -60V rating, SOT23 compactness, and 1A capability - making it optimal for space-constrained automotive switching where reliability and voltage robustness are jointly required.

FAQ
What is the maximum safe operating temperature for DPBT8105-7?
The DPBT8105-7 has an operating junction temperature range of -55°C to +150°C. Its maximum ambient temperature depends on power dissipation and PCB thermal design - at 600mW, ambient must stay below 25°C on standard FR-4 per AP02001 layout; derating curves in Figure 1 show linear reduction to zero power at 150°C ambient.
Is DPBT8105-7 pin-compatible with other SOT23 PNP transistors?
Yes - DPBT8105-7 uses standard SOT23 pinout (Emitter-Base-Collector, left-to-right top view), matching industry-standard PNP SOT23 devices like MMBT4403 and PN2907A. However, electrical parameters differ significantly; verify VCEO, IC, and hFE before substitution.
Does DPBT8105-7 require external protection against inductive kickback?
Yes - when switching inductive loads like relays or solenoids, a flyback diode (e.g., 1N4148) must be placed across the load. The DPBT8105-7's -60V VCEO rating does not guarantee survival of unclamped inductive spikes exceeding that voltage during turn-off.
How does the "Green" designation affect soldering process compatibility?
The "Green" designation indicates halogen-free, RoHS-compliant molding compound meeting UL 94V-0. It requires no special solder profile - standard lead-free reflow (J-STD-020D Level 1) applies. Matte tin plating ensures compatibility with both SnPb and SAC305 pastes per MIL-STD-202 Method 208.
