Product details
Overview
STPS60A150CS1 from STMicroelectronics is a radiation-hardened, dual common-cathode Schottky rectifier in a hermetic SMD.5 surface-mount package, rated for 2 × 30 A average forward current per diode and 150 V repetitive peak reverse voltage, with max forward voltage of 0.83 V at 30 A/125 °C - deployed in satellite power conversion stages requiring TID immunity up to 3 Mrad(Si) and SEB resistance under high-LET irradiation.
For engineers reviewing the STPS60A150CS1 datasheet, STPS60A150CS1 pinout, STPS60A150CS1 application, or STPS60A150CS1 equivalent, this part supports critical DC-DC converter output rectification, EPC (Electric Power Controller) secondary-side conduction, and radiation-tolerant PFC front-end designs where low VF, dV/dt immunity (10 kV/µs), and ESCC 5106/023 compliance are mandatory selection criteria.
Technical Context
This monolithic dual-die Schottky rectifier integrates two independent 30 A diodes sharing a common cathode terminal in a single SMD.5 ceramic/metal hermetic package. Its design eliminates parasitic inductance between dies and enables synchronized switching in high-reliability dual-phase outputs.
Characterized per ESCC 22900 (TID) and ESCC 25100 (SEE), it sustains full electrical performance after 3 Mrad(Si) exposure and shows no Single Event Burnout up to LET = 62.5 MeV·cm²/mg at ≤100% VRmax - verified across unbiased, forward-biased, and reverse-biased bias conditions during irradiation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 2 × 30 A - dual-diode rating enables parallel-output or interleaved converter topologies without external current-sharing components |
| VRRM | 150 V - supports 100 V nominal bus systems with 50% safety margin against transients in LEO/MEO satellite power rails |
| VF(max) | 0.83 V @ 30 A / 125 °C - reduces conduction loss by ≥25% vs. comparable Si fast recovery diodes, lowering thermal load in sealed modules |
| dV/dt | 10 kV/µs - prevents spurious turn-on during fast-switching GaN/SiC inverter transitions in motor drive or EPS subsystems |
| Rth(j-c) | 3.4 °C/W per diode - enables direct mounting to aluminum chassis without heatsink, simplifying thermal design in volume-constrained avionics enclosures |
| Tj(max) | +175 °C - allows operation in uncooled zones near propulsion electronics or solar array regulators where ambient exceeds 125 °C |
| Rad-Hard Qual | ESCC 5106/023 - flight-model qualified with full traceability, wafer-lot-level TID/SEE data, and serial-numbered certificates of conformance |
Pinout & Package
The STPS60A150CS1 uses the SMD.5 hermetic surface-mount package: ceramic base with metal lid, gold-plated terminations, 1 g mass, and 3-terminal configuration (Anode1, Anode2, Common Cathode). The top metallic lid is electrically isolated from all die and terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode A) | First diode anode | Connects to primary switching node of first phase; supports independent gate-drive referencing in dual-phase synchronous rectifiers |
| 2 (Anode B) | Second diode anode | Connects to second-phase switching node; matched thermal and electrical characteristics ensure balanced current sharing between dies |
| 3 (Cathode) | Common cathode | Single low-inductance return path for both diodes; minimizes ground bounce in high-di/dt aerospace converters |
Key Features
| Feature | Design Value |
|---|---|
| Monolithic dual die | Two matched Schottky junctions on one silicon substrate - eliminates inter-device parameter spread and ensures <±2% VF mismatch at 30 A |
| Hermetic SMD.5 package | Sealed ceramic/metal construction - achieves MIL-STD-883 Class H reliability and prevents moisture-induced parametric drift in vacuum or humid launch environments |
| TID immunity | 3 Mrad(Si) total ionizing dose tolerance - validated across bias states with zero parameter shift beyond spec limits post-irradiation and annealing |
| SEB resistance | No burnout observed at LET = 62.5 MeV·cm²/mg up to 100% VRmax - enables use in outer Van Allen belt orbits without derating |
| ESCC qualification | Complies fully with ESCC 5106/023/02 - includes wafer-lot traceability, 100% screening, and flight-model documentation per ESA requirements |
Applications
| Satellite Power Converter Output Stage | Electric Propulsion Control Unit (EPC) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VMI S150D20 | Same 150 V VRRM and dual-common-cathode topology, but rated for 2 × 20 A; lower Tj(max) = +150 °C; not ESCC-qualified | Acceptable for non-flight engineering models or terrestrial test benches where radiation hardness is not required | Select only for prototyping or ground-support equipment where full ESCC traceability and 3 Mrad(Si) validation are unnecessary |
| IXYS DSSK60-015A | Higher IF(AV) = 2 × 40 A, but TO-263 package (non-hermetic); no TID/SEE characterization; VF = 0.92 V @ 30 A/125 °C | Suitable for high-power industrial UPS or EV chargers, but unsuitable for space due to lack of radiation testing and packaging | Choose only for cost-sensitive, non-radiation environments where thermal performance outweighs hermeticity and qualification rigor |
Compared with VMI S150D20 and IXYS DSSK60-015A, STPS60A150CS1 uniquely delivers flight-grade ESCC 5106/023 qualification, hermetic SMD.5 packaging, and validated 3 Mrad(Si) immunity - making it the sole option for mission-critical LEO/MEO satellite power systems requiring zero-failure reliability.

FAQ
What is the difference between STPS60A150CS1 and STPS60A150CSG?
STPS60A150CS1 is the engineering model (design model) with gold-plated terminations and strip-pack packaging; STPS60A150CSG is the flight model qualified to ESCC 5106/023/02 with full lot traceability, wafer-level radiation test reports, and serialization. Both share identical electrical and thermal specs, but only the CSG variant carries flight certification.
Is the SMD.5 package lead-free and RoHS-compliant?
Yes - the SMD.5 package uses gold-plated terminations and complies with RoHS Directive 2011/65/EU. ST confirms full exemption from lead-based solder requirements per ECOPACK2 specifications, and the 1 g mass includes no restricted substances above threshold limits.
Can STPS60A150CS1 be used in zero-bias or reverse-biased TID testing configurations?
Yes - per DS12256 Rev 7 Section 2.1, the device was characterized under three bias conditions: unbiased, forward-biased, and reverse-biased, all at high dose rate. Performance remained within specification across all configurations after 3 Mrad(Si), confirming robustness in standby, conduction, and blocking states.
Does the common cathode configuration support independent thermal monitoring of each diode?
No - the monolithic dual die shares a single thermal path to the case; Rth(j-c) is specified per diode (3.4 °C/W) but measured from junction to common case surface. Independent thermal sensing requires external thermistors mounted adjacent to each anode pad, as no internal thermal sensors or separate cathode thermal vias are provided.
