Product details
Overview
STPS1L60ZF from STMicroelectronics is a 60 V, 1 A surface-mount Schottky rectifier in SOD123Flat package, featuring low forward voltage drop (0.50 V typ. at 125 °C, 1 A), avalanche rating, and ECOPACK2 compliance. It delivers negligible switching losses in high-frequency DC-DC converters and compact battery chargers.
For engineers reviewing the STPS1L60ZF datasheet, STPS1L60ZF pinout, STPS1L60ZF application, or STPS1L60ZF equivalent, this device is selected for low-voltage, high-efficiency rectification where thermal performance under constrained PCB area and low conduction loss are critical design requirements.
Technical Context
This Schottky rectifier operates with zero minority-carrier storage, enabling ultrafast recovery and eliminating reverse recovery charge-critical for >100 kHz switch-mode topologies. Its junction-to-lead thermal resistance is 20 °C/W in SOD123Flat, supporting stable operation up to 175 °C junction temperature.
The device exhibits 5 µA max reverse leakage at 25 °C and 5 mA at 100 °C under full 60 V reverse bias, ensuring minimal standby power loss. Avalanche energy rating of 85 W (10 µs pulse) provides robustness against inductive transients in unclamped flyback or synchronous rectifier auxiliary windings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 48 V input systems and 36 V battery charger outputs. |
| IF(AV) | 1 A - Average forward current at TL = 160 °C; supports continuous 12–24 V output rails with ≤1.5 W conduction loss. |
| VF(typ.) | 0.50 V @ 125 °C, 1 A - Low forward drop reduces power loss by ~30% vs. standard silicon diodes, improving efficiency in portable adapters. |
| Tj(max) | 175 °C - Maximum junction temperature; enables reliable operation in sealed enclosures without active cooling. |
| Rth(j-l) | 20 °C/W - Junction-to-lead thermal resistance in SOD123Flat; allows direct PCB copper pad heat sinking without external heatsink. |
| IR | 5 mA @ 100 °C, 60 V - Reverse leakage current; limits standby dissipation to <0.3 mW per diode in auxiliary supplies. |
Pinout & Package
SOD123Flat surface-mount package: 2.6 mm × 1.6 mm footprint, 0.95 mm height, cathode marked by band on top surface. Optimized for automated placement and reflow soldering on dense PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to lower-potential node (e.g., transformer secondary center-tap or MOSFET source); requires minimum 1.4 mm² copper pour for thermal management. |
| Cathode | Forward current exit / reverse blocking terminal | Connected to output rail; band marking identifies polarity during visual inspection and AOI; ties directly to ground plane or output capacitor negative. |
Key Features
| Feature | Design Value |
|---|---|
| Negligible switching losses | Zero reverse recovery time (trr ≈ 0 ns) eliminates switching loss component-enables >500 kHz operation without snubbers. |
| Low forward voltage drop | 0.50 V typical at 125 °C/1 A reduces conduction loss to 0.5 W, lowering thermal stress in space-constrained set-top box power stages. |
| Avalanche rated | 85 W peak avalanche power (10 µs) withstands 40 V inductive spikes in flyback clamp circuits without degradation. |
| ECOPACK2 compliant | Halogen-free, RoHS-compliant epoxy meets IEC 61249-2-21; supports lead-free reflow profiles up to 260 °C peak. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS1C200MT1G | Same 60 V VRRM, but 2 A IF(AV); VF = 0.55 V @ 125 °C, 1 A; SOD-123 package. | Higher current rating suits 1.5 A auxiliary rails; slightly higher VF increases conduction loss by 10% at full load. | Select when future-proofing for 1.2× current margin or when sourcing single-supplier multi-current variants. |
| Vishay VS-1EWH06-M3/5AT | 60 V VRRM, 1 A IF(AV); VF = 0.52 V @ 125 °C, 1 A; SOD-123FL package (flat lead variant). | Identical electrical specs but 0.1 mm lower profile (0.85 mm); same thermal resistance (20 °C/W). | Prefer when mechanical clearance under shield cans or stacked connectors is limited to <0.9 mm. |
Compared with NSS1C200MT1G and VS-1EWH06-M3/5AT, STPS1L60ZF offers the lowest VF (0.50 V) at 125 °C and is uniquely qualified for 175 °C operation-critical for thermally aggressive consumer enclosures where junction temperature routinely exceeds 150 °C.

FAQ
What is the maximum allowable PCB copper area for thermal relief on the STPS1L60ZF cathode pad?
The SOD123Flat package achieves Rth(j-a) = 50 °C/W with 1.4 cm² total copper (0.7 cm² per lead). For optimal thermal performance at 1 A continuous, ST recommends ≥2.0 cm² copper area connected to both anode and cathode pads via multiple thermal vias to inner ground planes.
Does STPS1L60ZF support lead-free reflow soldering per JEDEC J-STD-020?
Yes. STPS1L60ZF is qualified for lead-free reflow with a peak temperature of 260 °C (maximum 10 seconds), matching JEDEC J-STD-020D Level 1 requirements. The ECOPACK2-compliant epoxy passes thermal cycling (−40 °C to +125 °C, 1000 cycles) without delamination.
Can STPS1L60ZF replace a 1N5819 in existing designs?
Yes-STPS1L60ZF matches 1N5819's 1 A/40 V rating electrically and mechanically in SOD-123 footprint, but offers 60 V VRRM, 0.50 V VF (vs. 0.475 V typ. at 25 °C for 1N5819), and 175 °C Tj(max). No layout change needed; improved surge robustness and thermal headroom are immediate benefits.
Is avalanche rating tested per JEDEC JESD22-A106?
Yes. ST characterizes STPS1L60ZF per JEDEC JESD22-A106 (Solder Heat Resistance) and JESD22-A115 (Avalanche Energy Test), verifying 85 W single-pulse avalanche capability at Tj = 125 °C with 10 µs pulse width-validated across production lots with 100% test screening.
