Product details
Overview
STPS30H60CKY-TR from STMicroelectronics is an AEC-Q101-qualified dual-center-tab Schottky rectifier in PowerSO-20 (slug up) package, rated for 60 V reverse voltage, 30 A total average forward current (2 × 15 A per diode), and maximum 0.645 V forward voltage at 15 A/125 °C - designed for low-voltage automotive power conversion including engine control units and body electronics.
For engineers reviewing the STPS30H60CKY-TR datasheet, STPS30H60CKY-TR pinout, STPS30H60CKY-TR application, or STPS30H60CKY-TR equivalent, key selection criteria include dual-diode thermal coupling behavior, junction-to-case thermal resistance (0.95 °C/W per diode), conduction loss modeling (P = 0.385 × IF(AV) + 0.00867 × IF²(RMS)), and AEC-Q101 qualification for under-hood deployment.
Technical Context
This dual Schottky rectifier integrates two independent 15 A diodes sharing a common cathode tab and thermally coupled die structure within a single PowerSO-20 slug-up package. Its negligible switching losses and extremely fast recovery stem from majority-carrier conduction, eliminating minority-carrier storage delay.
Thermal design requires simultaneous evaluation of per-diode junction-to-case resistance (0.95 °C/W) and inter-diode coupling resistance (0.27 °C/W), as conduction in one diode directly elevates the junction temperature of the other - critical for sustained 30 A device-level operation at Tc = 140 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage per diode; defines safe operating range in 12 V/24 V automotive DC systems with load dump transients. |
| IF(AV) per diode | 15 A at Tc = 140 °C, δ = 0.5 - Continuous forward current rating per diode under pulsed thermal conditions; sets baseline for heatsink sizing. |
| VF(max) | 0.645 V at IF = 15 A, Tj = 125 °C - Worst-case forward drop used to calculate worst-case conduction loss (P = IF × VF). |
| Rth(j-c) per diode | 0.95 °C/W - Thermal resistance from junction to case; determines temperature rise above heatsink temperature under steady-state load. |
| IR(max) | 45 mA at VR = VRRM, Tj = 125 °C - Maximum reverse leakage per diode; impacts standby power loss and thermal runaway risk in parallel configurations. |
| IFS(M) | 250 A, tp = 10 ms sinusoidal - Non-repetitive surge capability; supports motor startup and alternator load dump survival. |
Pinout & Package
Package: PowerSO-20 (slug up) - thermally enhanced surface-mount package with exposed copper slug on underside for direct PCB thermal transfer; 20-pin layout with dual anode/cathode configuration and center-tab cathode connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2 | Anode 1 / Anode 2 | Independent anode terminals for each Schottky diode; must be externally connected together per datasheet note to achieve full 30 A device rating. |
| K (Pins 1–10, 11–20) | Common Cathode | Two electrically connected cathode groups (Pins 1–10 and 11–20) forming a single low-inductance, high-current cathode path tied to the exposed slug. |
| Slug (underside) | Thermal & Electrical Cathode | Exposed copper thermal pad serving as both primary heat dissipation path and low-impedance cathode return; requires solder mask defined stencil and full-surface reflow. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood use including temperature cycling, humidity bias, and mechanical shock per JESD22 standards. |
| Dual diode with shared cathode slug | Enables compact 30 A rectification with single thermal interface; eliminates need for discrete paralleling and associated layout imbalance. |
| Negligible switching losses | Majority-carrier operation ensures zero reverse recovery time (trr ≈ 0 ns), eliminating switching-related EMI and snubber requirements. |
| Low VF at high Tj | 0.645 V max at 125 °C/15 A enables >92% efficiency in 12 V buck converters at full load and elevated ambient. |
Applications
| Engine Control Unit (ECU) Power Supply | Automotive LED Headlamp Driver |
|---|---|
Use Scenario: Rectifying alternator output and regulating 12 V rail for microcontroller, sensors, and actuators in engine bay environments up to 150 °C ambient. IC Role / Device Role / Timing Role: Primary synchronous rectifier in secondary-side DC/DC stage; replaces MOSFETs where ultra-low VF and zero trr reduce system BOM count. Use Value: Enables stable 12 V supply under transient load dumps (250 A surges) while maintaining <1.5 °C/W total thermal resistance via slug-down mounting. | Use Scenario: High-efficiency current regulation for multi-string LED arrays in adaptive front lighting systems (AFS), operating continuously at 85 °C under hood. IC Role / Device Role / Timing Role: Output rectifier in constant-current buck converter driving 4–6 parallel LED strings at 3–5 A each. Use Value: Delivers <0.65 V VF across full temperature range, reducing conduction loss by 35% vs. standard silicon diodes and minimizing heatsink volume. |
| Body Control Module (BCM) DC-DC Converter | Start-Stop System Battery Management |
Use Scenario: 5 V/3.3 V point-of-load conversion from vehicle battery for infotainment, door modules, and window controllers. IC Role / Device Role / Timing Role: Secondary-side rectifier in isolated flyback or forward converter; handles intermittent 10–20 A peak loads during module wake-up. Use Value: Dual-diode architecture allows interleaved conduction to halve ripple current per diode, extending capacitor lifetime and reducing RMS heating. | Use Scenario: Bidirectional power path conditioning between 12 V starter battery and supercapacitor bank during engine cranking and regenerative braking. IC Role / Device Role / Timing Role: Low-loss freewheeling diode in synchronous rectifier stage; conducts reverse current during regen without reverse recovery spikes. Use Value: Zero reverse recovery prevents voltage overshoot on 12 V rail during rapid current reversal, protecting sensitive CAN/LIN transceivers. |

FAQ
What is the correct PCB layout practice for the PowerSO-20 slug?
The exposed copper slug must be fully soldered to a large, thermally optimized copper pour using a minimum of 90% stencil aperture coverage and ≥6 thermal vias (0.3 mm diameter, filled or capped) connecting to inner-layer ground or thermal planes. Avoid solder mask over the slug area to ensure low Rth(j-pcb).
Can STPS30H60CKY-TR operate with only one diode active?
Yes - either diode can be used independently with A1/K or A2/K connections. However, derating is required: maximum IF(AV) drops to 15 A per diode at Tc = 140 °C, and Rth(j-c) remains 0.95 °C/W. The unused anode must be left floating or tied to cathode; never shorted to another voltage rail.
How does thermal coupling affect simultaneous conduction in both diodes?
When both diodes conduct, junction temperature rise is calculated as ΔTj(diode1) = P₁ × 0.95 + P₂ × 0.27, where P₂ is power dissipated in the second diode. This coupling effect increases effective thermal resistance by up to 28% versus isolated operation - requiring conservative derating for continuous 30 A device-level current.
Is STPS30H60CKY-TR compatible with lead-free reflow profiles?
Yes - it is qualified for Pb-free assembly with peak reflow temperature of 245 °C ±5 °C (per JEDEC J-STD-020). The PowerSO-20 package meets MSL-3 moisture sensitivity level and requires ≤168 hours dry pack storage before reflow; bake-out is not required if sealed packaging remains unopened.
