Product details
Overview
BAS17,215 from NXP Semiconductors is a low-voltage stabistor diode in SOT23 package, designed for precision forward-voltage stabilization at 580–960 mV (IF = 0.1–100 mA), with 250 mW total power dissipation and 5 V reverse voltage rating. It serves as a bias stabilizer in class-B amplifier output stages, clamping element in signal conditioning circuits, and meter protection device in analog instrumentation.
For engineers reviewing the BAS17,215 datasheet, BAS17,215 pinout, BAS17,215 application, or BAS17,215 equivalent, key selection criteria include forward voltage tolerance at defined test currents (e.g., 725–805 mV @ 5 mA), differential resistance (80–120 Ω), reverse leakage (<5 µA @ 4 V), thermal resistance (500 K/W), and SOT23 pin configuration with pin 2 unconnected.
Technical Context
The BAS17,215 operates as a low-voltage Zener-like stabilization diode using heavily doped PN junction characteristics, delivering stable forward conduction without avalanche breakdown. Its VF exhibits tight distribution across production lots and predictable temperature coefficient (−1.8 mV/K @ 1 mA), enabling repeatable bias point setting in temperature-sensitive analog circuits.
It is not a switching diode or rectifier: its design prioritizes low-voltage regulation stability over fast recovery or high surge current capability. The unconnected pin 2 electrically isolates the die attach pad, reducing parasitic capacitance and improving high-frequency clamping fidelity up to 1 MHz (Cd = 140 pF @ 0 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage | 725–805 mV @ 5 mA: defines precise bias voltage window for class-B amplifier quiescent current control |
| Reverse Leakage | <5 µA @ 4 V: ensures minimal error current in clamping/meter protection paths |
| Differential Resistance | 80–120 Ω @ 2–0.5 mA: determines regulation stiffness against load current variation |
| Thermal Resistance | 500 K/W (junction-to-ambient): limits self-heating to <125 °C rise at 250 mW dissipation on FR4 PCB |
| Diode Capacitance | 140 pF @ 0 V, 1 MHz: sets upper frequency limit for AC signal clamping applications |
| Temperature Coefficient | −1.8 mV/K @ 1 mA: enables predictable drift compensation in precision analog references |
Pinout & Package
Package: SOT23 (TO-236AB), plastic surface-mount, 3-lead, 1.3 mm × 2.9 mm footprint, 1.1 mm height. Pin 2 is internally not connected and must remain floating in PCB layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Forward current entry point; connects to lower-potential node in bias/clamp circuit |
| 2 | Not Connected | No internal bond wire; must be left unconnected on PCB to avoid parasitic coupling |
| 3 | Cathode | Forward current exit point; connects to higher-potential node or ground reference |
Key Features
| Feature | Design Value |
|---|---|
| Low-Voltage Stabilization | Provides repeatable 580–960 mV forward drop across 0.1–100 mA, replacing resistive bias networks with tighter thermal tracking |
| SOT23 Footprint Compatibility | Enables high-density placement in space-constrained analog front-ends without requiring custom land patterns |
| Controlled Temperature Drift | −1.8 mV/K coefficient allows predictable offset correction in multi-stage amplifiers over −65 to +150 °C range |
| Low Capacitance Clamping | 140 pF capacitance supports clean clipping of audio and sensor signals up to 1 MHz without phase distortion |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS16,215 | Higher VF range (800–1100 mV @ 5 mA); 300 mW Ptot; same SOT23 pinout | Better suited for 1 V+ biasing; less suitable for sub-800 mV precision clamping | Select when target stabilization voltage exceeds 850 mV and higher power margin is needed |
| 1N4148W,115 | Standard switching diode; VF ≈ 720 mV @ 10 mA but no guaranteed stabilization spec; 500 mW Ptot | Lacks controlled VF distribution and temperature coefficient; used only where regulation tolerance >±100 mV is acceptable | Choose only for non-critical clipping where cost is primary constraint and VF drift is not monitored |
Compared with BAS16,215, the BAS17,215 offers tighter low-end VF control (down to 580 mV) critical for sub-800 mV biasing; versus 1N4148W,115, it provides documented stabilization performance, not just generic forward conduction.

FAQ
Is BAS17,215 a Zener diode?
No. The BAS17,215 is a low-voltage stabistor - a heavily doped PN junction diode optimized for stable forward-voltage conduction, not reverse-biased Zener breakdown. Its stabilization occurs in forward bias (580–960 mV), unlike Zeners which regulate in reverse bias. It has no specified Zener voltage or reverse breakdown parameter.
Can pin 2 be grounded or tied to PCB copper?
No. Pin 2 is internally not connected and must remain electrically floating. Connecting it to ground or any net introduces parasitic capacitance and potential noise coupling, degrading high-frequency clamping performance and violating the device's thermal and electrical specifications per the official NXP datasheet.
What is the maximum continuous forward current for BAS17,215?
The absolute maximum continuous forward current is 200 mA, as specified in the Limiting Values table. However, at 200 mA, forward voltage reaches 870–960 mV and power dissipation approaches 250 mW - the rated maximum. For reliable long-term operation, design for ≤100 mA to maintain junction temperature below 150 °C on standard FR4 PCB.
How does BAS17,215 differ from standard silicon signal diodes like 1N4148?
Unlike general-purpose diodes, the BAS17,215 is characterized and binned for tight forward-voltage distribution (e.g., 725–805 mV @ 5 mA) and specified temperature coefficient (−1.8 mV/K). It is intended for stabilization - not switching - and lacks reverse recovery time specs. Its differential resistance and capacitance are optimized for analog regulation, not speed.
