Product details
Overview
BAT15-098LRH from Nexperia is a silicon Schottky diode configured as an anti-parallel pair in a leadless TSLP-4-7 package, optimized for DBS mixer applications up to 12 GHz, phase detection, and RF modulation. It features 0.4 nH series inductance, 0.35–0.5 pF capacitance at 0 V/1 MHz, and low forward voltage (0.23–0.32 V at 10 mA), enabling high-frequency signal integrity in satellite receiver front-ends.
For engineers reviewing the BAT15-098LRH datasheet, BAT15-098LRH pinout, BAT15-098LRH application, or BAT15-098LRH equivalent, key selection criteria include RF capacitance matching, differential forward resistance (5.5 Ω typ.), thermal resistance (≤780 K/W), and AEC-Q101 qualification for automotive-grade reliability in RF signal paths.
Technical Context
This anti-parallel Schottky pair provides symmetrical RF conduction for balanced mixing and phase detection, with matched forward voltage (ΔVF ≤ 20 mV) ensuring amplitude and phase consistency across both diodes. Its low barrier design minimizes noise figure in small-signal RF stages.
The TSLP-4-7 leadless package delivers minimal parasitic inductance (0.4 nH) and controlled capacitance, supporting stable operation through X-band. Thermal resistance of ≤780 K/W enables reliable power handling up to 100 mW at junction temperatures ≤150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | Anti-parallel pair, leadless - enables balanced RF signal routing without external wiring asymmetry |
| Diode Capacitance (VR = 0 V, f = 1 MHz) | 0.35–0.5 pF - ensures minimal capacitive loading on 12 GHz mixer LO/RF ports |
| Differential Forward Resistance (IF = 10/50 mA) | 5.5 Ω typ. - reduces insertion loss and improves conversion efficiency in passive mixers |
| Forward Voltage (IF = 10 mA) | 0.23–0.32 V - lowers local oscillator drive requirement and improves dynamic range |
| Series Inductance (LS) | 0.4 nH - limits self-resonant frequency degradation in broadband RF layouts |
| Thermal Resistance (Junction–Soldering Point) | ≤780 K/W - supports continuous 100 mW dissipation with ≤76 °C case temperature rise |
| Reverse Voltage Rating | 4 V - defines maximum RF peak swing tolerance before breakdown in DBS LNB circuits |
Pinout & Package
TSLP-4-7 is a 4-terminal, leadless surface-mount package with exposed thermal pad; terminals are arranged in a compact 1.3 × 1.1 mm footprint for high-density RF PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode A | RF input node for first diode leg in anti-parallel configuration |
| 2 | Cathode of Diode A / Anode of Diode B | Common node enabling anti-parallel connection without external trace routing |
| 3 | Cathode of Diode B | RF output or IF return path in balanced mixer topologies |
| 4 | Exposed Thermal Pad | Primary heat conduction path to PCB ground plane; must be soldered for rated thermal performance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar anti-parallel Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MACOM MADP-000907-14020T | Higher CT (0.65 pF), higher VF (0.35 V @ 10 mA), SOT-23 package | Less suitable for >10 GHz due to higher capacitance; better for <6 GHz IF stages | Select when board space allows larger SOT-23 and target frequency is ≤6 GHz |
| Skyworks SMS7630-061 | Single diode (not anti-parallel), lower CT (0.25 pF), same VF range | Requires external anti-parallel layout; adds parasitics and layout complexity | Select only when discrete layout control is needed and thermal budget permits separate die mounting |
Compared with BAT15-098LRH, MADP-000907-14020T trades bandwidth for higher power handling, while SMS7630-061 offers lower capacitance but forfeits integrated symmetry-making BAT15-098LRH optimal for production-ready, miniaturized 12 GHz mixer designs.

FAQ
What is the recommended bias condition for optimal noise figure in mixer applications?
For minimum noise figure below 12 GHz, bias BAT15-098LRH at 0.5–1.0 mA DC with RF choke isolation. This maintains junction temperature stability while preserving low ΔVF matching and sub-0.5 dB NF in double-balanced configurations per Nexperia's application note AN11124.
Is the TSLP-4-7 package compatible with standard reflow profiles for lead-free assembly?
Yes - the TSLP-4-7 package meets IPC/JEDEC J-STD-020D MSL1 rating and is qualified for peak reflow temperatures up to 260 °C (liquidus) with ≤60 sec above 220 °C, provided thermal pad is fully soldered to maximize heat dissipation.
How does the anti-parallel configuration improve carrier suppression in modulators?
The monolithic anti-parallel layout ensures identical parasitic LS and CT across both diodes, enabling precise cancellation of even-order harmonics and carrier feedthrough. Measured carrier suppression exceeds 35 dB at 11 GHz in balanced modulator evaluations per Nexperia's EHD07082 characterization data.
Can BAT15-098LRH replace BAT15-099LRH in existing designs?
Yes - both share identical TSLP-4-7 packaging, anti-parallel configuration, and electrical specs (VF, CT, RthJS). BAT15-098LRH replaces BAT15-099LRH with no layout or bias changes; the "098" suffix denotes updated internal process control, not functional deviation.
