Product details
Overview
BZX84-B13,215 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 (TO-236AB) package, rated for 13 V nominal breakdown voltage at 5 mA test current, 250 mW total power dissipation, and 150 °C maximum junction temperature - used for precision low-power voltage reference and overvoltage protection in power supply feedback paths.
For engineers reviewing the BZX84-B13,215 datasheet, BZX84-B13,215 pinout, BZX84-B13,215 application, or BZX84-B13,215 equivalent, key selection criteria include Zener voltage tolerance (±2 %), differential resistance (≤170 Ω), reverse current at 10.4 V (≤0.1 μA), temperature coefficient (+7.0 mV/K), and thermal resistance (330 K/W to solder point).
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining stable output by conducting reverse current above its specified Zener voltage. Its 13 V nominal breakdown is defined at IZ = 5 mA with ±2 % tolerance, and exhibits a positive temperature coefficient of +7.0 mV/K, indicating increasing regulation voltage with rising junction temperature.
The diode supports transient suppression via non-repetitive peak reverse power dissipation up to 40 W (100 μs pulse), while steady-state operation is limited to 250 mW on FR4 PCB with standard footprint. Its 170 Ω maximum differential resistance at IZ = 5 mA defines regulation stiffness under load variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.7 V to 13.3 V at IZ = 5 mA - defines tight regulation window for reference stability |
| Differential Resistance (rdif) | ≤170 Ω at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Current (IR) | ≤0.1 μA at VR = 10.4 V - ensures minimal leakage below knee voltage |
| Temperature Coefficient (SZ) | +7.0 mV/K at IZ = 5 mA - quantifies drift rate per degree Celsius rise |
| Total Power Dissipation (Ptot) | 250 mW at Tamb ≤ 25 °C on FR4 PCB - sets continuous DC power limit |
| Non-repetitive Peak Power (PZSM) | 40 W for tp = 100 μs - enables short surge clamping without failure |
| Junction Temperature (Tj) | −55 °C to +150 °C - defines operational and storage thermal envelope |
Pinout & Package
Package: SOT23 (TO-236AB), surface-mount plastic package with 3 leads, 1.9 mm × 1.1 mm body size, 0.45 mm lead pitch, and standard reflow footprint per Figure 12.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node in shunt regulation |
| 2 | Not Connected (n.c.) | Internally unconnected; must remain floating or grounded per layout best practice |
| 3 | Cathode (K) | Zener breakdown terminal; connects to regulated voltage node and current-limiting resistor |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables tighter output regulation than ±5 % variants, reducing need for post-regulation trimming |
| 250 mW power rating in SOT23 | Supports higher current regulation than sub-200 mW Zeners without requiring larger packages |
| 170 Ω max differential resistance | Limits output voltage shift to ≤0.85 V under ±5 mA load change, improving line/load regulation |
| +7.0 mV/K temperature coefficient | Provides predictable, linear drift for compensated reference designs across −55 °C to +125 °C |
| 40 W non-repetitive peak power | Clamps ESD transients (e.g., IEC 61000-4-2 Level 4) without degradation when properly current-limited |
Applications
| Power Supply Feedback Reference | Overvoltage Clamp Protection |
|---|---|
Use Scenario: Stabilizing output voltage in isolated flyback or buck converter feedback loop using optocoupler-coupled TL431 alternative. IC Role / Device Role / Timing Role: Shunt voltage reference providing precise 13 V threshold to control PWM duty cycle. Use Value: ±2 % tolerance ensures output accuracy within ±0.26 V at 13 V, reducing need for factory calibration. |
Use Scenario: Protecting microcontroller I/O pins against 15 V rail surges in industrial sensor interface circuits. IC Role / Device Role / Timing Role: Passive clamp limiting voltage to 13.3 V before damage threshold of 16 V. Use Value: 40 W surge rating absorbs 100 μs transients without parametric shift, preserving long-term reliability. |
| Low-Power Voltage Monitor | ADC Reference Stabilization |
Use Scenario: Detecting brown-out condition in battery-powered IoT node when supply drops below 12.7 V. IC Role / Device Role / Timing Role: Threshold detector triggering reset signal via comparator input. Use Value: 0.1 μA reverse leakage at 10.4 V minimizes quiescent current drain in always-on monitoring path. |
Use Scenario: Providing stable 13 V reference for 12-bit SAR ADC in portable medical sensor front-end. IC Role / Device Role / Timing Role: Precision analog reference source with low dynamic impedance. Use Value: 170 Ω differential resistance limits reference droop to <1.7 mV per 10 μA ADC bias current change. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5243B | 13 V ±5 % tolerance, 350 mW rating, 100 Ω rdif, −1.5 mV/K tempco | Higher power but looser tolerance; better for coarse clamping, worse for precision reference | Select when surge robustness > regulation accuracy; avoid where tempco matching matters |
| Vishay BZX84-C13 | 13 V ±5 % tolerance, same 250 mW rating, 170 Ω rdif, +7.0 mV/K tempco | Identical thermal and dynamic behavior but wider voltage spread (12.4–14.1 V) | Select only for cost-sensitive, non-critical regulation; not suitable for feedback loops requiring <±0.3 V error |
Compared with BZX84-B13,215, MMBZ5243B trades tighter regulation for higher surge capacity and lower impedance, while BZX84-C13 retains identical thermal design but sacrifices voltage accuracy - making the B-series optimal for applications needing both precision and SOT23 footprint constraints.

FAQ
What is the guaranteed Zener voltage range for BZX84-B13,215 at 5 mA?
The guaranteed Zener voltage range is 12.7 V to 13.3 V at IZ = 5 mA, reflecting its ±2 % tolerance specification. This range is validated per IEC 60134 limiting values and confirmed in Table 8 of the Rev. 7 datasheet under "BZX84-B13" entry, with min/max values explicitly listed as 12.70 V and 13.30 V.
Can BZX84-B13,215 be used in place of a 12 V Zener diode?
No - BZX84-B13,215 is specified exclusively for 13 V nominal regulation and is not interchangeable with 12 V Zeners. Its minimum Zener voltage (12.7 V) exceeds typical 12 V part maximums (e.g., BZX84-B12 max = 12.2 V), risking overvoltage in circuits relying on exact 12 V clamping or reference.
How does the n.c. pin (Pin 2) affect PCB layout?
Pin 2 is internally not connected and must remain electrically floating; it may be tied to ground for mechanical stability if required by assembly process, but must never be routed to active circuit nodes. The SOT23 footprint in Figure 12 shows no copper connection for Pin 2, and thermal modeling assumes no heat conduction through this terminal.
Is BZX84-B13,215 qualified for automotive applications?
No - per Section 13 revision history and Legal Information section, this device is non-automotive qualified. Nexperia explicitly states that BZX84_SER Rev. 7 products are "changed to non-automotive qualification" and directs users to their website for automotive (-Q) alternatives. It lacks AEC-Q101 stress testing and automotive-grade traceability.
