Product details
Overview
BAS85,135 from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, housed in a hermetically sealed glass SOD80C surface-mount package. It delivers 30 V reverse voltage rating, 200 mA forward current capability, and 800 mV forward voltage at 100 mA - enabling ultra-high-speed switching and low-loss clamping in space-constrained signal path protection circuits.
For engineers reviewing the BAS85,135 datasheet, BAS85,135 pinout, BAS85,135 application, or BAS85,135 equivalent, this diode is selected for precision voltage clamping, high-frequency blocking, and ESD-robust interface protection where low VF, fast recovery, and thermal stability across −65 °C to +125 °C ambient are critical design requirements.
Technical Context
The BAS85,135 uses a planar Schottky junction architecture with an integrated guard ring to suppress edge breakdown and improve ruggedness under transient stress. Its hermetically sealed glass SOD80C package ensures long-term reliability in humid or corrosive environments without encapsulation degradation.
With 10 pF capacitance at 1 V reverse bias and 2.3 μA reverse leakage at 25 V, it supports RF-sensitive applications up to ~100 MHz while maintaining sub-1 ns reverse recovery time (inferred from Schottky structure and 300 μs pulse test compliance). Junction-to-ambient thermal resistance is 320 K/W on standard FR4 PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - defines maximum allowable DC or peak AC reverse bias before breakdown; suitable for 24 V system rail clamping. |
| Forward Current (IF) | 200 mA continuous - supports moderate-power signal routing and logic-level translation without derating below 85 °C. |
| Forward Voltage (VF) | 800 mV at 100 mA - enables low conduction loss in high-efficiency clamp or OR-ing circuits. |
| Reverse Leakage (IR) | 2.3 μA at 25 V - ensures minimal standby current in battery-backed or low-power monitoring paths. |
| Capacitance (Cd) | 10 pF at 1 V, 1 MHz - preserves signal integrity in <100 MHz digital or analog switching nodes. |
| Junction Temp (Tj) | 125 °C max - allows operation in industrial enclosures with limited airflow and no active cooling. |
Pinout & Package
Encapsulated in a hermetically sealed glass SOD80C package (3.3–3.7 mm length × 1.45–1.60 mm width × 0.3 mm height), with tin-plated metal discs at each end for reliable reflow and wave soldering. The cathode is marked by a visible band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to circuit ground or lower-potential node; polarity indicator for correct orientation in clamping or rectification paths. |
| 2 | Anode | Connected to input signal or higher-potential rail; forms forward-biased path during clamping or blocking events. |
Key Features
| Feature | Design Value |
|---|---|
| Guard-ring protected junction | Suppresses edge breakdown under voltage transients, improving reliability in surge-prone interfaces. |
| Hermetically sealed glass package | Eliminates moisture ingress and intermetallic degradation, ensuring >20-year shelf life and stable parametrics. |
| Low VF at low IF | 240 mV at 0.1 mA enables accurate biasing in precision detector or reference circuits. |
| High VR/IF ratio | 30 V / 200 mA rating supports wide supply range compatibility without sacrificing current headroom. |
Applications
| USB Interface Protection | Industrial Sensor Signal Conditioning |
|---|---|
|
Use Scenario: Clamping ESD transients on USB D+/D− lines before entering PHY ICs. IC Role / Device Role / Timing Role: Fast-switching voltage clamp limiting excursion to ±3.6 V. Use Value: 10 pF capacitance avoids signal rise-time degradation; 800 mV VF ensures minimal offset in bidirectional data lines. |
Use Scenario: Blocking reverse polarity on 4–20 mA loop-powered sensor outputs. IC Role / Device Role / Timing Role: Unidirectional current path enforcer with low forward drop. Use Value: 200 mA rating accommodates loop fault currents; 2.3 μA IR prevents loading of microamp-level sensor bias networks. |
| RF Front-End Bias Sequencing | Automotive LIN Bus Termination |
|
Use Scenario: Isolating bias voltage rails in LNA or mixer stages during power-up sequencing. IC Role / Device Role / Timing Role: Low-capacitance DC blocking diode in RF signal path. Use Value: 10 pF Cd minimizes impedance mismatch at 900 MHz; glass package ensures stable C vs. temperature. |
Use Scenario: Protecting LIN transceiver pins against load-dump-induced reverse transients. IC Role / Device Role / Timing Role: Transient voltage suppressor with fast turn-on response. Use Value: Guard ring withstands repetitive 30 V spikes; 125 °C Tj rating matches under-hood thermal profiles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5711 | Higher VF (950 mV @ 100 mA), larger DO-35 through-hole package, no guard ring. | Not suitable for automated SMT assembly; less robust under repetitive overvoltage stress. | Select only for legacy through-hole designs where board real estate and ESD immunity are secondary. |
| MBR0530T1G | Higher IF (500 mA), TO-236AB package, VF = 450 mV @ 100 mA, but Cd = 35 pF. | Lower conduction loss but excessive capacitance degrades >30 MHz signal integrity. | Prefer for power OR-ing; avoid in high-speed data line clamping due to bandwidth limitation. |
Compared with 1N5711 and MBR0530T1G, BAS85,135 uniquely balances low capacitance, guard-ring ruggedness, and SMT compatibility - making it optimal for compact, high-reliability signal-path protection where both speed and transient resilience are required.

FAQ
Is BAS85,135 suitable for reflow soldering?
Yes. The SOD80C package is qualified for standard lead-free reflow profiles per J-STD-020, with tin-plated terminations and hermetic glass construction ensuring no popcorning or delamination. Peak temperature tolerance is validated to 260 °C for 10 seconds.
What is the meaning of the marking band on BAS85,135?
The black marking band identifies Pin 1 as the cathode terminal. This aligns with IEC 60747-2 and JEDEC standards for diode polarity marking, ensuring unambiguous orientation during automated placement and visual inspection.
Does BAS85,135 have automotive qualification?
No. BAS85,135 is not AEC-Q101 qualified. It is rated for industrial temperature range (−65 °C to +125 °C) but lacks automotive-specific stress testing, lot traceability, and failure rate reporting required for automotive use.
How does the guard ring improve reliability?
The integrated guard ring redistributes electric field intensity away from the junction periphery, preventing premature edge breakdown during repetitive 30 V transients. This extends operational lifetime in surge-prone applications like I/O port protection and sensor interfacing.
