Product details

Overview

BAV20,113 from NXP Semiconductors is a hermetically sealed glass axial-leaded switching diode in SOD27 (DO-35) package, rated for 150 V continuous reverse voltage and 200 V repetitive peak reverse voltage, with 50 ns max reverse recovery time and 625 mA repetitive peak forward current. It serves as a high-speed rectifier or signal clamping device in video output stages of color TV and digital voltmeters.

For engineers reviewing the BAV20,113 datasheet, BAV20,113 pinout, BAV20,113 application, or BAV20,113 equivalent, key selection criteria include reverse recovery time under 50 ns, thermal resistance of 375 K/W (junction-to-ambient), and cathode-marked axial lead configuration for unambiguous PCB orientation in industrial test equipment.

Technical Context

The BAV20,113 is a planar silicon switching diode optimized for general-purpose high-speed applications where moderate voltage blocking and fast transient response are required. Its 5 pF diode capacitance at 0 V and 100 nA reverse leakage at VRmax support stable operation in RF-coupled video signal paths and precision analog front-ends.

Thermal performance is defined for FR4 PCB mounting with 10 mm lead length: junction-to-ambient thermal resistance is 375 K/W, and maximum junction temperature is 175 °C. The device operates reliably up to 150 °C junction temperature with only 100 μA IR at VRmax, enabling use in thermally constrained industrial enclosures.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum repetitive reverse voltage before avalanche conduction begins; defines safe AC/DC blocking capability in line-powered circuits
V_R	150 V - maximum continuous reverse voltage; sets DC bias limit for clamp or snubber networks
t_rr	50 ns - measured reverse recovery time at IF = IR = 30 mA, RL = 100 Ω; ensures minimal switching loss in 1–10 MHz signal routing
I_FRM	625 mA - peak repetitive forward current; supports pulsed operation in sample-and-hold or pulse-shaping circuits
C_d	5 pF - diode capacitance at f = 1 MHz, VR = 0 V; enables low-distortion coupling in video bandwidths up to ~30 MHz
R_{th j-a}	375 K/W - junction-to-ambient thermal resistance on FR4 with 10 mm leads; determines derating curve for ambient temperatures above 50 °C

Pinout & Package

BAV20,113 uses a hermetically sealed axial-leaded SOD27 (DO-35) glass package with cathode indicated by a black band on the body. Leads are tinned copper, 0.56 mm diameter, 25.4 mm minimum length, and compatible with wave soldering per JEDEC SC-40.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential node in rectification or clamping; requires trace width ≥ 0.3 mm for 250 mA continuous
Cathode	Forward current exit / reverse voltage terminal	Marked by black band; ties to higher-potential rail or signal return; critical for polarity-sensitive video sync circuits

Key Features

Feature	Design Value
Hermetic glass sealing	Prevents moisture ingress and long-term parameter drift in humid industrial environments (e.g., lab-grade test equipment)
50 ns reverse recovery	Enables clean edge transitions in 10–20 MHz video blanking and horizontal deflection timing circuits
100 nA reverse leakage at VRmax	Minimizes DC offset error in precision analog sampling paths operating near full-scale reverse bias
375 K/W thermal resistance	Allows direct mounting on FR4 without heatsink for ≤150 mW dissipation in compact oscilloscope front-end designs

Applications

Video Output Stage

Digital Voltmeter Input Protection

Use Scenario: Clamping sync pulses and blanking intervals in PAL/NTSC color TV video amplifiers.

IC Role / Device Role / Timing Role: Fast-switching clamp diode limiting signal swing to ±0.7 V during retrace periods.

Use Value: 5 pF capacitance avoids high-frequency roll-off; 50 ns t_rr prevents ghosting artifacts in 15.625 kHz horizontal sweep.

Use Scenario: Input overvoltage protection for 3½-digit DVM front-end op-amps.

IC Role / Device Role / Timing Role: Bidirectional ESD clamp shunting transients >±150 V to ground/rail.

Use Value: 200 V V_RRM withstands accidental probe contact with mains; 100 nA IR preserves input impedance >10 GΩ.

Oscilloscope Vertical Amplifier

Industrial Signal Conditioning

Use Scenario: DC restoration and pedestal clamping in 100 MHz bandwidth vertical preamplifiers.

IC Role / Device Role / Timing Role: AC-coupled baseline stabilizer using cathode-follower configuration.

Use Value: Low 1.0 V V_F at 100 mA minimizes baseline shift; hermetic seal prevents calibration drift over 5-year service life.

Use Scenario: Isolation and level translation between 24 V PLC I/O and 3.3 V microcontroller GPIO.

IC Role / Device Role / Timing Role: Reverse-biased isolation diode blocking backfeed from field-side power rails.

Use Value: 150 V V_R rating exceeds industrial surge immunity requirements (IEC 61000-4-5 Level 3); DO-35 axial form factor fits legacy board layouts.

Equivalent & Alternatives

The following parts are listed as comparable options for similar switching diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4148,113	Lower V_RRM (100 V), faster t_rr (4 ns), higher leakage (25 nA @ 20 V)	Better for <1 MHz logic-level clamping; unsuitable for 150 V video supply rails	Select when speed dominates voltage rating and PCB space is constrained
BAV21,113	Higher V_RRM (250 V), identical t_rr, same package and thermal specs	Drop-in replacement where 200 V margin is insufficient (e.g., CRT anode supply snubbers)	Choose for enhanced reverse voltage headroom without layout change

Compared with BAV20,113, 1N4148,113 trades voltage robustness for nanosecond switching in low-voltage logic interfaces, while BAV21,113 extends reverse blocking by 50 V with no thermal or footprint penalty-making it ideal for legacy design refreshes requiring higher reliability margins.

FAQ

What is the cathode identification method for BAV20,113?

The cathode is marked by a distinct black band on the glass body of the DO-35 package. This band aligns with the cathode lead during axial insertion and must be oriented toward the more positive potential in rectifier or clamp configurations. Visual inspection under 10× magnification confirms band continuity and absence of chipping.

Can BAV20,113 replace 1N4148 in high-voltage applications?

No-BAV20,113 has higher reverse voltage ratings (200 V vs. 100 V) but slower reverse recovery (50 ns vs. 4 ns). It is suitable only where voltage margin is critical and switching frequency remains below 2 MHz. Substitution requires verification of t_rr-induced overshoot in the target circuit's load conditions.

What is the maximum continuous forward current at 70 °C ambient?

Per Figure 2 in the NXP datasheet, the maximum continuous forward current drops to 180 mA at T_amb = 70 °C when mounted on FR4 with 10 mm leads. This derating reflects thermal resistance of 375 K/W and assumes no forced airflow or copper pour enhancement.

Is BAV20,113 RoHS compliant?

Yes-BAV20,113 meets RoHS Directive 2011/65/EU. NXP confirms lead-free termination (matte tin plating) and exemption from hazardous substance restrictions per Annex II, with full compliance documentation available under document number 9397 750 05895.
