Product details
Overview
BAT6804WE6327BTSA1 from Infineon Technologies is a silicon Schottky diode configured as a common-anode dual diode pair in SOT-23 package, rated for 8 V reverse voltage, 130 mA forward current, and 150 mW total power dissipation at TS ≤ 61°C, optimized for VHF/UHF mixer and high-speed switching applications.
For engineers reviewing the BAT6804WE6327BTSA1 datasheet, BAT6804WE6327BTSA1 pinout, BAT6804WE6327BTSA1 application, or BAT6804WE6327BTSA1 equivalent, key selection criteria include low junction capacitance (1 pF @ 0 V), low differential forward resistance (10 Ω @ 5 mA), low forward voltage (340 mV typ. @ 1 mA), ESD sensitivity handling requirements, and thermal resistance (RthJS ≤ 590 K/W).
Technical Context
This dual common-anode Schottky diode enables balanced signal mixing and fast switching in RF front-ends, with matched diode characteristics critical for image rejection and harmonic suppression. Its 1 pF junction capacitance and 10 Ω dynamic resistance support operation up to UHF frequencies while maintaining low insertion loss.
The device operates with a maximum junction temperature of 150°C and requires strict ESD handling (HBM Class 2). Thermal derating curves confirm usable forward current down to ambient temperatures of –55°C and up to 150°C storage range, with defined pulse load capability per duty cycle and pulse width.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 8 V - Maximum DC blocking voltage before breakdown; defines safe operating range in RF bias networks. |
| Forward Current (IF) | 130 mA - Continuous DC current rating; sets upper limit for local oscillator drive or detector current. |
| Junction Capacitance (CT) | 1 pF @ 0 V, 1 MHz - Low capacitance enables minimal signal loading and wideband matching in 30–1000 MHz mixers. |
| Differential Forward Resistance (RF) | 10 Ω @ 5 mA, 10 kHz - Low series resistance ensures high conversion efficiency and low noise figure in passive mixers. |
| Forward Voltage (VF) | 340 mV typ. @ 1 mA - Enables low-voltage biasing and reduces LO injection power requirements. |
| Thermal Resistance (RthJS) | ≤ 590 K/W - Limits junction-to-solder-point temperature rise; constrains PCB copper area and layout for thermal management. |
Pinout & Package
SOT-23 plastic surface-mount package with gull-wing leads; 3-pin configuration supporting common-anode dual-diode topology. Pin 1 and Pin 2 are cathodes; Pin 3 is the shared anode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode of Diode 1 | RF signal path output for first diode leg; connects to IF or LO port in balanced mixer topologies. |
| Pin 2 | Cathode of Diode 2 | Second RF signal path output; used for differential detection or image-reject mixing configurations. |
| Pin 3 | Common Anode | Shared DC bias node; must be properly decoupled and thermally anchored to manage power dissipation and thermal stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low junction capacitance | 1 pF @ 0 V - Enables broadband impedance matching without external tuning components in 400–900 MHz bands. |
| Matched dual-diode structure | Common-anode configuration with tightly controlled parameter spread - supports balanced mixer architectures with >25 dB image rejection. |
| ESD robustness | HBM Class 2 (≥2 kV) - Requires handling per JEDEC J-STD-020; avoids gate oxide damage during assembly without added protection circuitry. |
| RoHS-compliant packaging | Pb-free SOT-23 - Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260°C). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode mixer and detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAR63-04W-E6327 | Lower CT (0.6 pF), higher IF (200 mA), same SOT-323 package but different pinout (cathode-anode-cathode). | Superior for >1 GHz designs; unsuitable for direct pin-for-pin replacement due to reversed terminal assignment. | Select when UHF+ performance is prioritized and board layout allows re-routing. |
| NSVRB0540HT1G | Single diode, higher VR (40 V), higher VF (450 mV typ.), TO-236AB package, no common-anode pairing. | Lacks matched dual structure; requires two devices and external balancing for mixer use. | Choose only for non-mixer applications where higher reverse voltage is mandatory and space permits dual placement. |
Compared with BAR63-04W-E6327 and NSVRB0540HT1G, BAT6804WE6327BTSA1 uniquely delivers matched dual-diode performance in SOT-23 with optimal CT–RF–VF trade-off for sub-1 GHz mixer efficiency, while avoiding layout redesign or component doubling.

FAQ
What is the maximum operating frequency for BAT6804WE6327BTSA1 in mixer applications?
The device is characterized for VHF/UHF operation up to 1 GHz, with verified performance in 900 MHz mixer circuits per Infineon's EHD07103 and EHD07101 application plots. Its 1 pF capacitance and 10 Ω resistance support usable conversion gain through 862 MHz broadcast bands, though system-level bandwidth depends on external matching network design.
Is BAT6804WE6327BTSA1 pin-compatible with BAT68-04 or BAT68-04W?
Yes - BAT6804WE6327BTSA1 uses the SOT-23 package and shares identical pinout (cathode–cathode–common anode) and marking "84s" with BAT68-04 and BAT68-04W. All three comply with the same JEDEC MO-203AA outline and thermal derating profile (TS ≤ 61°C).
Does this diode require external ESD protection in PCB layout?
No - the device incorporates internal ESD protection rated to HBM Class 2 (≥2 kV), but handling precautions (grounded workstation, ionized air, anti-static packaging) are mandatory prior to soldering. No external TVS or RC snubbers are needed for typical RF detector or mixer use cases.
Can BAT6804WE6327BTSA1 be used in series or parallel configurations beyond its common-anode dual structure?
No - the internal die structure integrates two Schottky junctions sharing a single anode metallization; external series connection would short both cathodes, and parallel use of multiple units introduces mismatch-induced imbalance. It must be used strictly as a common-anode dual diode per datasheet configuration.
