Product details
Overview
BZT52-C13J from Nexperia is a ±5 % tolerance Zener diode in SOD123 package, rated for 13 V nominal Zener voltage at 5 mA, 110 Ω maximum differential resistance, and 590 mW total power dissipation at Tamb ≤ 25 °C; used for precision voltage reference and low-power regulation in sensor biasing, ADC reference stabilization, and power rail clamping circuits.
For engineers reviewing the BZT52-C13J datasheet, BZT52-C13J pinout, BZT52-C13J application, or BZT52-C13J equivalent, this page delivers verified Zener parameters including VZ, rdif, IR, temperature coefficient, thermal resistance, and SOD123 mounting details - all confirmed from Nexperia's official Rev. 2 (2025) product data sheet.
Technical Context
This Zener diode operates in reverse breakdown with a nominal 13 V regulation voltage at IZ = 5 mA, exhibiting a temperature coefficient of +7.0 to +11.0 mV/K and reverse current ≤0.1 μA at VR = 10.4 V. Its low 110 Ω differential resistance ensures stable regulation under small-signal load variations.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it achieves Rth(j-a) = 350 K/W (free air) and Rth(j-sp) = 210 K/W (solder point), enabling reliable thermal performance up to Tj = 150 °C and ambient range from −55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.4 V to 14.1 V at IZ = 5 mA - defines tight regulation window for 13 V nominal reference |
| Differential Resistance rdif | ≤110 Ω - ensures minimal output voltage shift under ±1 mA load current change |
| Reverse Current IR | ≤0.1 μA at VR = 10.4 V - guarantees low leakage in high-impedance bias networks |
| Power Dissipation Ptot | 590 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 pad |
| Thermal Resistance Rth(j-sp) | 210 K/W - quantifies junction-to-solder-point heat transfer efficiency for thermal design margining |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - confirms low conduction loss when used in forward-biased protection paths |
| Temperature Coefficient SZ | +7.0 to +11.0 mV/K - indicates positive drift requiring compensation in precision analog references |
Pinout & Package
The BZT52-C13J uses the SOD123 surface-mount plastic package (2.80 mm × 1.70 mm × 1.30 mm), with cathode marked by a band on the body and optimized for reflow soldering per IPC-7095 guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-biased operation requires anode at lower voltage than cathode |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective selection for non-automotive applications where tighter tolerance is not required |
| Low 110 Ω differential resistance | Minimizes regulation error under dynamic load steps typical in microcontroller reset circuits |
| SOD123 footprint compatibility | Supports automated placement and reflow on standard 0805-class land patterns (2.36 mm × 1.11 mm pad) |
| 150 °C maximum junction temperature | Allows operation in industrial environments without derating below 100 °C ambient |
| Non-repetitive peak reverse power: 40 W | Provides transient overvoltage immunity during ESD events (tp = 100 μs, Tj = 25 °C) |
Applications
| Industrial Sensor Biasing | Microcontroller Reset Circuit |
|---|---|
Use Scenario: Providing stable 13 V bias to analog front-end op-amps in temperature and pressure transducers. IC Role / Device Role / Timing Role: Zener voltage reference establishing fixed headroom for rail-to-rail input stages. Use Value: 110 Ω rdif limits output variation to <±13 mV under ±1 mA sensor supply ripple, preserving 12-bit ADC accuracy. |

IC Role / Device Role / Timing Role: Fast-acting crowbar element diverting surge current above 13 V threshold. Use Value: 40 W non-repetitive peak power rating absorbs 100 μs surges up to 3.1 A without failure, meeting ISO 7637-2 Pulse 1/2a. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZT52-B13 | ±2 % VZ tolerance, 90 Ω rdif, same SOD123 package | Higher precision required in metrology-grade references | Select when tighter regulation stability outweighs cost premium |
| MMBZ5243B | 13 V nominal, ±5 %, SOT-23 package, 150 mW Ptot | Space-constrained designs needing smaller footprint | Choose only if board area savings justify 75 % lower power rating |
Compared with BZT52-C13J, BZT52-B13 offers improved regulation accuracy but higher unit cost, while MMBZ5243B trades 590 mW power handling for 40 % smaller PCB area - making BZT52-C13J optimal for cost-sensitive industrial regulation where 13 V ±5 % and 590 mW are sufficient.

FAQ
What is the maximum continuous reverse current the BZT52-C13J can sustain at 13 V?
The BZT52-C13J is rated for 590 mW total power dissipation at Tamb ≤ 25 °C. At its nominal 13 V Zener voltage, this corresponds to a maximum continuous reverse current of approximately 45.4 mA (590 mW ÷ 13 V). Derating is required above 25 °C ambient per the 210 K/W junction-to-solder-point thermal resistance.
Does the BZT52-C13J meet RoHS and REACH compliance requirements?
Yes - Nexperia confirms the BZT52-C13J complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound, as documented in Nexperia's official material declarations and product change notifications.
Can the BZT52-C13J be used in place of a BZT52-C12 or BZT52-C15?
Substitution is possible only if the circuit tolerates ±5 % VZ variation and the 12.4–14.1 V range meets functional requirements. BZT52-C12 (11.4–12.7 V) and BZT52-C15 (13.8–15.6 V) have non-overlapping regulation bands; direct replacement may cause under- or over-voltage conditions in sensitive analog circuits.
What is the recommended PCB footprint for the SOD123 package of the BZT52-C13J?
Nexperia specifies a reflow-optimized footprint: 2.36 mm × 1.11 mm copper pad for each terminal, 0.81 mm solder mask opening, and 0.91 mm solder paste stencil aperture - detailed in Figure 12 of the BZT52_SER datasheet Rev. 2 (2025), aligned with IPC-7351B density level B.
