Product details
Overview
BUK7K13-60EX from Nexperia is a dual N-channel standard-level MOSFET in LFPAK56D (SOT1205) package, rated for 60 V VDS, 10 mΩ RDS(on) at 10 A/25 °C, and qualified to AEC-Q101 for automotive use. It integrates two independent power switches with true standard gate drive (VGS(th) > 1 V at 175 °C), enabling direct microcontroller interfacing in 12 V systems.
For engineers reviewing the BUK7K13-60EX datasheet, BUK7K13-60EX pinout, BUK7K13-60EX application, or BUK7K13-60EX equivalent, this device supports thermally demanding automotive switching tasks including solenoid control, transmission actuation, and high-current motor drive where repetitive avalanche capability and 175 °C junction operation are critical.
Technical Context
This dual MOSFET uses TrenchMOS technology and features isolated drain-source paths with shared thermal mounting base. Each channel delivers 40 A continuous current at Tmb = 25 °C and sustains 213 A peak pulsed current with 82 mJ non-repetitive avalanche energy rating.
Its gate threshold remains functional up to 175 °C (VGS(th) ≥ 1 V), and RDS(on) increases only 2.2× from 25 °C to 175 °C (typical 8 mΩ → 18 mΩ), ensuring predictable on-state behavior across full automotive temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 60 V - Maximum drain-source blocking voltage; suitable for 12 V automotive battery systems with load-dump transients. |
| RDS(on) | 8–10 mΩ @ 10 A, 25 °C - Low conduction loss enabling <1 W dissipation per FET at 10 A DC, reducing heatsink requirements. |
| ID (cont) | 40 A @ Tmb = 25 °C - Package-limited continuous current; derates to 38 A at 100 °C mounting base temperature. |
| EAS | 82 mJ - Non-repetitive avalanche energy rating; allows safe operation during inductive turn-off events without external snubbers. |
| Tj max | 175 °C - Junction temperature limit; enables operation in engine bay or transmission control modules without derating. |
| QGD | 9.7 nC - Gate-drain charge determining switching speed and Miller plateau duration; supports fast 20 ns turn-off delay. |
| Rth(j-mb) | 2.36 K/W - Junction-to-mounting-base thermal resistance; enables efficient heat transfer to PCB copper or heatsink. |
Pinout & Package
LFPAK56D (SOT1205) is a thermally enhanced surface-mount package with exposed metal mounting base and 8 leads. Its low-profile design (max height 1.05 mm) and optimized copper layout deliver superior power density and thermal performance versus SO-8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | S1 | Source terminal of FET1 - referenced to ground or low-side return path for first switch. |
| 2 | G1 | Gate terminal of FET1 - accepts standard 10 V logic-level drive; VGS(th) > 1 V even at 175 °C. |
| 3 | S2 | Source terminal of FET2 - electrically isolated from S1; enables independent half-bridge or dual-load configurations. |
| 4 | G2 | Gate terminal of FET2 - fully independent control; no internal coupling between G1 and G2. |
| 5, 6 | D2 | Drain terminals of FET2 - paralleled pins for lower inductance and higher current handling on second channel. |
| 7, 8 | D1 | Drain terminals of FET1 - paralleled pins for reduced package inductance and improved switching robustness. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, transmission, and body electronics per stress test requirements. |
| Repetitive avalanche rated | Capable of repeated unclamped inductive switching events without degradation, verified per JEDEC JESD22-A106. |
| 175 °C junction rating | Operates reliably at full current capability up to ambient +125 °C with proper PCB thermal design. |
| True standard-level gate | VGS(th) ≥ 1 V at 175 °C ensures consistent turn-on with 3.3 V or 5 V MCU GPIOs without level-shifting. |
| Low RDS(on) × QG figure-of-merit | Typical 8 mΩ × 30.1 nC = 241 mΩ·nC - balances conduction and switching losses for high-efficiency 10–100 kHz PWM. |
Applications
| Transmission Solenoid Control | Engine Cooling Fan Drive |
|---|---|
|
Use Scenario: Precise PWM-controlled activation of hydraulic solenoids in automatic transmission valve bodies. IC Role / Device Role / Timing Role: Dual high-side switch delivering 12 V/5–15 A pulses with <20 ns turn-off delay and avalanche energy absorption during coil de-energization. Use Value: Eliminates need for external flyback diodes or snubbers due to 82 mJ EAS rating and integrated body diode recovery (trr = 25.6 ns). |
Use Scenario: Variable-speed control of brushed DC cooling fans in under-hood environments. IC Role / Device Role / Timing Role: Low-side dual switch enabling bidirectional fan control or parallel current sharing for >20 A loads. Use Value: 10 mΩ RDS(on) minimizes I²R loss at full load, reducing thermal stress on PCB and extending fan lifetime in 125 °C ambient conditions. |
| Brake Actuator Power Stage | Start-Stop System Load Switch |
|
Use Scenario: High-reliability power switching for electro-hydraulic brake actuators requiring fail-safe shutdown. IC Role / Device Role / Timing Role: Dual-channel isolation switch providing redundant current paths with independent gate control and thermal monitoring. Use Value: AEC-Q101 qualification and 175 °C operation ensure functional safety compliance (ISO 26262 ASIL-B ready) without derating. |
Use Scenario: Controlled engagement/disengagement of auxiliary loads (e.g., HVAC compressor) during engine stop/start cycles. IC Role / Device Role / Timing Role: High-current load switch managing up to 40 A surges during cold cranking while maintaining VGS(th) stability at elevated temperatures. Use Value: Standard-level gate enables direct connection to vehicle's 3.3 V CAN/LIN microcontrollers, eliminating level-shift circuitry and BOM cost. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual N-channel automotive MOSFET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STL220N6F7 | 60 V, 2.2 mΩ RDS(on) @ 100 A, but single-channel in PowerFLAT 5x6; requires two devices for dual function. | Higher current density but lacks integrated dual topology; needs extra PCB area and gate drivers. | Select when maximum current per channel (>60 A) is required and board space permits discrete duplication. |
| ON Semiconductor NTMFS5C675NL | 60 V, 5.2 mΩ RDS(on) @ 10 A, single-channel PowerTrench® 5x6; not AEC-Q101 qualified. | Lower RDS(on) but no automotive qualification or avalanche rating; unsuitable for safety-critical systems. | Consider only for non-automotive industrial 12 V switching where qualification and ruggedness are secondary. |
Compared with STL220N6F7 and NTMFS5C675NL, BUK7K13-60EX uniquely combines dual-channel integration, AEC-Q101 qualification, 175 °C operation, and verified avalanche capability in a single compact LFPAK56D package-making it optimal for space-constrained, thermally aggressive automotive power stages.

FAQ
Is BUK7K13-60EX pin-compatible with other LFPAK56D dual MOSFETs?
No-BUK7K13-60EX has a unique pin assignment (S1-G1-S2-G2-D2-D2-D1-D1) optimized for thermal symmetry and low-inductance dual-channel routing. Other LFPAK56D dual MOSFETs like BUK7K14-60E use different pinouts; PCB layout must be verified against SOT1205 mechanical drawing.
What is the maximum recommended gate resistor for 100 kHz PWM operation?
For 100 kHz switching with minimal overshoot, a 5 Ω external gate resistor is validated per datasheet Figure 14. This value balances turn-on speed (td(on) = 8.4 ns) and ringing suppression, given QG(tot) = 30.1 nC and typical driver output impedance.
Does BUK7K13-60EX include integrated ESD protection?
Yes-each gate terminal is protected to HBM ±2 kV per JESD22-A114, confirmed by Nexperia's qualification testing. No external TVS diodes are required for standard handling, though system-level ESD protection remains necessary per ISO 10605.
Can both channels operate simultaneously at full 40 A each?
No-total package power dissipation limits combined current. At Tmb = 25 °C, Ptot = 64 W max. With RDS(on) ≈ 9 mΩ per channel, simultaneous 40 A operation would generate 2 × (40² × 0.009) = 28.8 W, well within limit-but thermal coupling requires careful PCB copper design to maintain Tj ≤ 175 °C.
