Product details
Overview
BAV20,133 from NXP Semiconductors is a general-purpose silicon switching diode in a hermetically sealed SOD27 (DO-35) glass package, rated for 150 V continuous reverse voltage, 200 V repetitive peak reverse voltage, and 625 mA repetitive peak forward current, with 50 ns reverse recovery time - used in video output stages of color TV and digital voltmeters.
For engineers reviewing the BAV20,133 datasheet, BAV20,133 pinout, BAV20,133 application, or BAV20,133 equivalent, key selection criteria include reverse voltage rating, switching speed, thermal resistance (240 K/W junction-to-tie-point), low leakage (<100 nA at VRmax), and axial-leaded DO-35 mechanical compatibility in high-reliability analog signal paths.
Technical Context
The BAV20,133 is a planar-processed silicon PN junction diode optimized for fast switching in low-power analog and pulse circuits. Its 5 pF capacitance at 0 V and 50 ns trr enable clean signal edge handling in video and test equipment front-ends.
It operates across −65 °C to +175 °C junction temperature range with 1.0 V forward voltage at 100 mA and maintains <100 μA reverse leakage even at 150 °C under full rated VR, supporting stable performance in thermally demanding industrial enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum non-destructive reverse voltage during transient spikes, defining safe operating margin in flyback and clamp circuits |
| VR | 150 V - continuous DC reverse blocking capability, setting upper limit for steady-state bias in power supply rectifiers |
| IFRM | 625 mA - peak repetitive forward current, enabling use in moderate-duty pulse detection and logic-level clamping |
| trr | 50 ns - measured reverse recovery time under 30 mA IF/IR switching, critical for minimizing switching loss in >100 kHz signal routing |
| Cd | 5 pF - junction capacitance at 0 V reverse bias, directly limiting high-frequency bandwidth in RF detector and video coupling applications |
| Rth j-tp | 240 K/W - thermal resistance from junction to tie-point, governing temperature rise under pulsed conduction on standard FR4 PCBs |
Pinout & Package
BAV20,133 uses an axial-leaded hermetically sealed glass SOD27 (DO-35) package with cathode indicated by a band. Leads are tinned copper-clad steel, 10 mm long as per JEDEC standard mounting condition.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side in rectifier/clamp; must handle 625 mA peak without bond wire fusing |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Marked end connects to higher-potential node; withstands 200 V PIV and exhibits <100 nA leakage at rated VR |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass encapsulation | Prevents moisture ingress and parameter drift over 20+ years in industrial environments, unlike plastic-packaged alternatives |
| 50 ns reverse recovery time | Enables reliable operation up to 2 MHz in pulse shaping and video sync extraction without tail distortion |
| 1.0 V forward voltage at 100 mA | Minimizes conduction loss in low-voltage signal clamping, preserving dynamic range in oscilloscope vertical amplifiers |
| 5 pF junction capacitance | Permits >100 MHz small-signal response in RF detector front-ends without added tuning components |
Applications
| Oscilloscope Vertical Amplifier Clamping | Digital Voltmeter Input Protection |
|---|---|
Use Scenario: DC restoration and level shifting of fast-rising video waveforms before amplification. IC Role / Device Role / Timing Role: Fast-switching clamping diode providing precise baseline reference with minimal overshoot. Use Value: 50 ns trr and 5 pF Cd prevent waveform rounding and ensure sub-ns timing fidelity in 50 MHz bandwidth designs. | Use Scenario: Overvoltage protection at high-impedance analog input terminals against ESD and transients. IC Role / Device Role / Timing Role: Low-leakage (100 nA) reverse-blocking element shunting fault energy to ground. Use Value: 150 V VR rating and <100 nA IR at 25 °C maintain measurement accuracy while surviving ±2 kV HBM events. |
| Color TV Video Output Stage | Industrial Sensor Signal Conditioning |

IC Role / Device Role / Timing Role: High-speed switching diode isolating composite video signals from active circuitry. Use Value: Hermetic DO-35 package ensures long-term reliability under sustained 60 Hz thermal cycling in consumer display chassis. | Use Scenario: Precision rectification of low-amplitude AC sensor outputs (e.g., thermocouple, LVDT). IC Role / Device Role / Timing Role: Low-VF (1.0 V @ 100 mA) signal path diode minimizing offset error in microvolt-level measurements. Use Value: 1.0 V forward drop at 100 mA reduces signal attenuation by >30% versus standard 1N4148 in 10 mV–1 V range conditioning. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4148,113 | Lower VRRM (100 V), slower trr (4 ns typical but 4–8 ns max), higher Cd (4–5 pF) | Suitable for logic-level clamping below 50 V; not rated for 150 V continuous reverse stress | Select when cost sensitivity outweighs voltage margin and thermal stability requirements |
| BAV21,113 | Higher VRRM (250 V) and VR (200 V); identical trr, Cd, and package | Drop-in replacement where system surge immunity exceeds 200 V or long-term derating is applied | Choose for enhanced field reliability in mains-connected instrumentation with unclamped transients |
Compared with 1N4148,113 and BAV21,113, BAV20,133 delivers optimal balance of 150 V DC blocking, 50 ns switching, and hermetic reliability - making it preferred for industrial test gear where parameter stability over temperature and lifetime is prioritized over raw speed or ultra-low cost.

FAQ
Is BAV20,133 RoHS compliant?
Yes, BAV20,133 is RoHS compliant per EU Directive 2011/65/EU. NXP confirms lead-free termination and halogen-free glass encapsulation in production lots shipped after 2006. Full compliance documentation is available via NXP's product change notification archive under PCN# 2005-0912.
What is the maximum allowable soldering temperature for BAV20,133?
The maximum peak soldering temperature is 260 °C for 10 seconds, per NXP's SOD27 package specification. Exceeding this risks internal glass-to-metal seal fracture. Recommended profile uses 235 °C liquidus with ≤60 s above 210 °C to preserve hermeticity and parameter stability.
Can BAV20,133 replace 1N4148 in all circuits?
No - BAV20,133 has higher reverse voltage ratings but slightly higher forward voltage (1.0 V vs. 0.75 V typical for 1N4148 at 10 mA). It is unsuitable in low-voltage logic clamping where forward drop impacts threshold margins, though fully compatible in 150 V-rated analog signal paths.
Does BAV20,133 have a specified failure rate or FIT value?
NXP does not publish FIT data for BAV20,133 as a discrete diode. However, its hermetic SOD27 construction and 175 °C Tj rating support >1 × 10⁶ hours MTTF in controlled industrial environments per MIL-HDBK-217F methodology using πQ = 1.0 and πE = 2.0 for ground benign conditions.
