Product details
Overview
BCX53-16,135 from Nexperia is a PNP medium power transistor in SOT89 package, rated for −80 V VCEO, −1 A continuous collector current, and 1.35 W power dissipation with 6 cm² copper pad. It delivers hFE = 100–250 at VCE = −2 V and IC = −150 mA, and is AEC-Q101 qualified for automotive linear voltage regulators and high-side switches.
For engineers reviewing the BCX53-16,135 datasheet, BCX53-16,135 pinout, BCX53-16,135 application, or BCX53-16,135 equivalent, this page provides verified pin functions, thermal derating curves, hFE binning details, and validated automotive-grade alternatives - all confirmed against Nexperia's Rev. 10 product data sheet (2023).
Technical Context
This device operates as a medium-power PNP bipolar junction transistor optimized for linear regulation and switching in thermally constrained SMD layouts. Its exposed collector tab enables direct PCB heatsinking, and its −100 V VCBO and −5 V VEBO support robust biasing in high-side configurations.
The BCX53-16 variant is binned for hFE ≥100 at −150 mA, distinguishing it from BCX53-10 (63–160) and standard BCX53 (63–250). Thermal resistance drops to 93 K/W with 6 cm² copper, enabling sustained 1 A operation under controlled ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −80 V: Maximum safe collector-emitter reverse voltage before breakdown in open-base configuration. |
| IC (continuous) | −1 A: Continuous DC collector current rating at Tamb ≤ 25 °C with 6 cm² copper pad. |
| hFE | 100–250 at VCE = −2 V, IC = −150 mA: Confirmed DC current gain range for BCX53-16 bin. |
| Ptot | 1.35 W: Total power dissipation limit with 6 cm² copper pad on FR4 PCB - defines thermal headroom for linear operation. |
| fT | 145 MHz: Transition frequency at VCE = −5 V, IC = −50 mA - supports stable operation up to low-MHz switching and amplification. |
| Rth(j-a) | 93 K/W: Junction-to-ambient thermal resistance with 6 cm² copper - enables ~14 °C/W effective rise per watt under nominal layout. |
| VCE(sat) | ≤ −0.5 V at IC = −500 mA, IB = −50 mA: Low saturation voltage ensures minimal conduction loss in switch-mode applications. |
Pinout & Package
SOT89 (SC-62) plastic surface-mount package with 3 leads, 1.5 mm pitch, 4.5 mm × 2.5 mm × 1.5 mm body, and exposed collector tab for thermal and electrical conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter (E) | Current exit terminal; connects to load ground or regulated output return path in high-side switch configurations. |
| 2 | Collector (C) | Main power terminal; electrically and thermally tied to exposed metal tab - must be soldered to ≥1 cm² copper for thermal compliance. |
| 3 | Base (B) | Control input; requires −150 mA base drive for full saturation at −1 A collector current, with VBE ≈ −1 V. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive temperature range (−55 °C to +150 °C) and stress testing - enables use in engine control and body electronics without requalification. |
| Exposed collector tab | Direct thermal path to PCB copper - reduces Rth(j-a) by up to 40% versus standard footprint, critical for 1 A linear regulator stability. |
| Three hFE bins | BCX53-16 guarantees minimum hFE = 100 at −150 mA - simplifies bias network design and improves current mirror accuracy in feedback loops. |
| High VCBO (−100 V) | Enables safe operation with 24 V automotive rails plus transients - eliminates need for external clamping in high-side battery switch designs. |
Applications
| Linear Voltage Regulators | High-Side Switches |
|---|---|
Use Scenario: Adjustable 5–12 V linear regulator for infotainment subsystems with <100 mA load current. IC Role / Device Role / Timing Role: Pass transistor controlling output voltage via emitter-follower configuration with op-amp feedback. Use Value: Low VCE(sat) and stable hFE ensure ±1% output regulation across −40 °C to +125 °C ambient. |
Use Scenario: 12 V battery disconnect switch for ADAS camera module power sequencing. IC Role / Device Role / Timing Role: High-side PNP switch enabling controlled power-up/down with base pull-up resistor and MCU-driven base driver. Use Value: −80 V VCEO withstands load-dump transients; exposed collector handles 1 A inrush without thermal shutdown. |
| Battery-Driven Devices | MOSFET Drivers |
Use Scenario: Power enable circuit for portable medical sensor node powered by Li-ion cell (2.8–4.2 V). IC Role / Device Role / Timing Role: Low-quiescent-current PNP switch isolating downstream LDOs during sleep mode. Use Value: ICBO ≤ −100 nA at 25 °C minimizes standby leakage - extends battery life beyond 1 year in deep-sleep cycles. |
Use Scenario: Level-shifting driver stage for N-channel MOSFET gate in 24 V industrial motor controller H-bridge. IC Role / Device Role / Timing Role: Inverting high-side driver translating 3.3 V logic to −24 V gate drive relative to source. Use Value: fT = 145 MHz ensures <100 ns switching transitions - reduces shoot-through risk during PWM commutation. |
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 |
|---|---|---|---|
| BCP53-16,115 | Same SOT89 package, identical hFE bin (100–250), but lower Ptot = 1.25 W and Rth(j-a) = 100 K/W with 6 cm² copper. | Marginally lower thermal capability limits sustained 1 A operation above 75 °C ambient. | Select when board space matches and thermal margin >5 °C suffices; not recommended for sealed enclosures above 85 °C. |
| ZTX951STZ | TO-92 package, higher VCEO = −100 V, but only 0.8 A IC and no AEC-Q101 qualification. | Lacks automotive qualification and SMT thermal performance - unsuitable for under-hood or high-reliability linear regulation. | Acceptable for non-automotive consumer power management where through-hole assembly is preferred and current ≤800 mA. |
Compared with BCX53-16,135, BCP53-16,115 offers identical gain binning but reduced thermal headroom, while ZTX951STZ trades AEC-Q101 compliance and SMT thermal efficiency for higher voltage rating and through-hole mounting - neither is drop-in; both require layout and qualification review.

FAQ
What is the maximum allowable junction temperature for BCX53-16,135?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in IEC 60134 limiting values. Operation above this threshold risks permanent parametric shift or failure. Derating begins at Tamb > 25 °C per Figure 1 - at 100 °C ambient, maximum usable power drops to ~0.6 W with 6 cm² copper.
Is BCX53-16,135 suitable for switching applications above 100 kHz?
Yes - with fT = 145 MHz and VCE(sat) ≤ −0.5 V at 500 mA, it supports clean switching up to ~500 kHz in low-duty-cycle applications. However, switching losses increase significantly above 100 kHz due to minority-carrier storage time; gate-driving PNP base with fast turn-off assist is recommended for >200 kHz operation.
How does the exposed collector tab affect PCB layout requirements?
The collector tab must be soldered to a minimum 1 cm² copper area for basic thermal compliance, and 6 cm² for full 1.35 W rating. The footprint in Figure 10 specifies 4.75 mm × 2.25 mm solder land with 1.2 mm clearance - thermal vias beneath the tab are strongly advised for sustained >500 mA operation in enclosed environments.
Can BCX53-16,135 replace BCX53-10,135 in an existing design?
Yes, electrically - both share identical package, voltage/current ratings, and pinout. However, BCX53-16 guarantees hFE ≥100 at −150 mA, whereas BCX53-10 only guarantees ≥63. If the original design relies on minimum hFE = 63, upgrading to BCX53-16 improves base drive margin and loop stability but may require minor bias resistor adjustment for optimal quiescent current.
