Product details
Overview
BCX5316E6433HTMA1 from Infineon Technologies is a PNP silicon bipolar junction transistor designed for audio frequency driver and output stages in linear amplifiers and switching applications. It features VCEO = 80 V, IC = 1 A continuous, VCE(sat) ≤ 0.5 V at IC = 500 mA / IB = 50 mA, hFE = 100–250 (at IC = 150 mA), and SOT-89 surface-mount package. It is RoHS-compliant and AEC-Q101 qualified for automotive-grade reliability.
For engineers reviewing the BCX5316E6433HTMA1 datasheet, BCX5316E6433HTMA1 pinout, BCX5316E6433HTMA1 application, or BCX5316E6433HTMA1 equivalent, key selection criteria include guaranteed hFE range at high current, low saturation voltage under 500 mA load, thermal resistance RthJS ≤ 15 K/W, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This PNP BJT operates in active, saturation, and cutoff regions with DC current gain specified across three test conditions: hFE ≥ 100 at IC = 150 mA (BCX53-16 variant), ≥ 160 at IC = 500 mA, and ≥ 250 at IC = 5 mA - enabling stable biasing in both small-signal pre-driver and medium-power output stages.
Its breakdown ratings (V(BR)CEO = 80 V, V(BR)CBO = 100 V, V(BR)EBO = 5 V) and low VCE(sat) support robust operation in 24 V automotive supply rails and Class-AB audio output configurations where collector swing exceeds ±30 V peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - supports operation in 24 V automotive systems with ≥2× supply headroom for transient spikes |
| IC (continuous) | 1 A - enables direct drive of medium-power loads such as relay coils or speaker outputs up to 5 W |
| VCE(sat) | ≤ 0.5 V @ IC = 500 mA, IB = 50 mA - limits conduction loss to < 250 mW, critical for thermally constrained SOT-89 layout |
| hFE | 100–250 - ensures predictable base drive requirements across production lots and temperature (−55 °C to 150 °C) |
| RthJS | ≤ 15 K/W - allows 2 W dissipation with ≤30 K junction-to-solder-point rise, supporting PCB copper pour design |
| fT | 125 MHz typ. - sufficient for AF amplification up to 20 kHz with >60 dB gain margin |
| AEC-Q101 | Qualified - meets stress-test requirements for automotive electronics including HTOL, TC, and HTRB |
Pinout & Package
SOT-89 package: single-row, 3-pin surface-mount plastic case with exposed emitter pad for thermal enhancement and mechanical anchoring. Dimensions: 4.5 mm × 2.5 mm × 1.5 mm (L × W × H), pitch 2.3 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | Emitter terminal | Connected to ground or low-side return path; large metal pad provides primary thermal conduction path to PCB |
| 2 (Collector) | Collector terminal | High-current output node; routed to heat sink plane or power rail; polarity defines PNP current sink behavior |
| 3 (Base) | Base control terminal | Current-controlled input requiring ~50 mA for full saturation at 500 mA load; sensitive to ESD (VEBO = 5 V) |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage PNP capability | VCEO = 80 V enables use in 24 V/48 V industrial and automotive power stages without cascading |
| Low saturation voltage | VCE(sat) ≤ 0.5 V reduces power loss and self-heating in linear regulator pass elements and audio output stages |
| AEC-Q101 qualification | Validated for automotive under-hood environments including temperature cycling, humidity, and lifetime reliability testing |
| Complementary NPN pairing | Matches BCX56-16 for push-pull amplifier designs requiring matched hFE and VCE(sat) characteristics |
| Pb-free & RoHS compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260 °C) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCX53-16 (Infineon) | Same die, identical electrical specs; differs only in marking and reel packaging (E6433HTMA1 denotes specific tape-and-reel configuration) | No functional difference; same PCB footprint, thermal profile, and reliability data | Select BCX53-16 for non-tape applications or when alternate reel size required |
| MJD2955G (ON Semiconductor) | TO-220 package, higher IC = 10 A, but VCEO = 60 V and no AEC-Q101 qualification | Suitable for high-current industrial switching but not automotive due to lower voltage rating and qualification gap | Choose only for non-automotive, high-current, through-hole designs where thermal mass outweighs SMT density needs |
Compared with BCX53-16 and MJD2955G, BCX5316E6433HTMA1 uniquely combines AEC-Q101 qualification, 80 V blocking, SOT-89 compactness, and guaranteed hFE ≥ 100 at 150 mA - making it optimal for space-constrained automotive and industrial control nodes requiring long-term reliability.

FAQ
What is the maximum continuous collector current for BCX5316E6433HTMA1?
The maximum continuous collector current is 1 A at TS ≤ 120 °C. Derating applies above this case temperature: total power dissipation drops linearly to zero at 150 °C junction temperature. Pulse current up to 1.5 A is allowed for tp ≤ 10 ms with duty cycle < 2%.
Is BCX5316E6433HTMA1 pin-compatible with BCX53-16?
Yes - both share identical SOT-89 package, pin 1 (emitter), pin 2 (collector), pin 3 (base) assignment, and mechanical footprint. The suffix "E6433HTMA1" indicates a specific tape-and-reel packaging format (1,000 pcs/reel, ø180 mm), not a functional or electrical variant.
Does this transistor require a heatsink in typical applications?
Not necessarily: with RthJS ≤ 15 K/W and Ptot = 2 W at TS = 120 °C, a standard 100 mm² 2-oz copper pour under the emitter pad typically suffices for ≤1.5 W continuous dissipation. Heatsinking is recommended only for sustained >1.8 W operation or ambient >85 °C.
Can BCX5316E6433HTMA1 be used as a direct replacement for BCX51 or BCX52 variants?
No - BCX51 (VCEO = 45 V) and BCX52 (VCEO = 60 V) have lower voltage ratings and different hFE bins. Substituting BCX5316E6433HTMA1 may over-specify voltage capability but risks gain mismatch and unintended bias point shifts in existing circuits calibrated for lower hFE.
