Product details
Overview
BZT52-C15J from Nexperia is a ±5 % tolerance Zener diode in SOD123 package, rated for 15 V nominal regulation at 5 mA, with 110 Ω max differential resistance and 590 mW total power dissipation, used for precision voltage reference and low-power rail stabilization in consumer and industrial power management circuits.
For engineers reviewing the BZT52-C15J datasheet, BZT52-C15J pinout, BZT52-C15J application, or BZT52-C15J equivalent, key selection criteria include Zener voltage tolerance (±5 %), thermal resistance (210 K/W junction-to-solder-point), reverse current at 13.8 V (≤0.05 μA), cathode-anode polarity marking, and SOD123 footprint compatibility with IPC-7351B reflow land patterns.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across load variations, with temperature coefficient of +9.2 to +13.0 mV/K at IZ = 5 mA - indicating positive drift that must be compensated in high-stability references. Its low 110 Ω differential resistance ensures minimal output voltage shift under ±1 mA load current change.
The device uses planar epitaxial construction for repeatable breakdown characteristics and is qualified per JEDEC JESD22-A108 for 1000-hour storage at 150 °C. It is non-automotive qualified and intended for commercial/industrial ambient ranges (−55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 13.8 V to 15.6 V at IZ = 5 mA - defines usable regulation window under standard test conditions |
| Differential Resistance rdif | 110 Ω max - limits output voltage variation to ≤110 mV per 1 mA load current step |
| Reverse Current IR | ≤0.05 μA at VR = 13.8 V - ensures negligible leakage in standby-biased reference networks |
| Total Power Dissipation Ptot | 590 mW at Tamb ≤ 25 °C on 1 cm² cathode pad - sets maximum continuous DC power handling |
| Thermal Resistance Rth(j-sp) | 210 K/W - determines junction temperature rise above solder point under steady-state bias |
| Forward Voltage VF | ≤0.9 V at IF = 10 mA - defines conduction loss when used in forward-biased protection paths |
| Junction Temperature Tj | 150 °C max - constrains maximum allowable die temperature during operation |
Pinout & Package
SOD123 surface-mount plastic package: 2.80 mm × 1.70 mm body, 0.70 mm lead pitch, cathode marked by single band; designed for reflow soldering only with recommended footprint per Figure 12 (0.91 mm × 2.36 mm Cu pad, 0.81 mm solder mask opening).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking band identifies this terminal; carries reverse current during Zener operation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for voltage reference function |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage reference without trimming in non-critical analog monitoring circuits |
| Low 110 Ω differential resistance | Supports stable regulation under dynamic load steps up to ±1 mA without external buffering |
| 150 °C maximum junction temperature | Permits operation in enclosed industrial enclosures with limited airflow and no forced cooling |
| SOD123 package with standard IPC footprint | Ensures drop-in compatibility with automated pick-and-place and reflow processes across PCB assembly lines |
| Non-repetitive peak reverse power: 40 W (100 μs) | Provides transient overvoltage clamping capability during ESD or surge events in signal line protection |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
|
Use Scenario: Providing stable 15 V reference for ADC voltage dividers and op-amp bias networks in battery-powered sensors. IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to fix reference node potential relative to ground. Use Value: Delivers <±10 mV drift over −40 °C to +85 °C due to predictable +10.5 mV/K tempco and low rdif. |
Use Scenario: Protecting microcontroller I/O pins from 24 V transients induced by relay coil flyback in PLC input modules. IC Role / Device Role / Timing Role: Cathode tied to protected line, anode to ground - conducts during overvoltage to clamp voltage at ~15.6 V. Use Value: Limits transient duration to <100 μs with 40 W non-repetitive peak power rating, preventing latch-up or gate oxide damage. |
| Current Source Bias | Level Translation |
|
Use Scenario: Generating constant 1 mA bias current for phototransistor amplifiers in optical isolation circuits. IC Role / Device Role / Timing Role: Series-connected with resistor to create two-terminal current source using Zener's flat IV knee. Use Value: Maintains current stability within ±3 % over supply variations from 18 V to 22 V due to tight VZ tolerance and low rdif. |
Use Scenario: Shifting logic levels between 3.3 V MCU GPIO and 15 V industrial sensor outputs. IC Role / Device Role / Timing Role: Anode connected to 3.3 V rail, cathode to sensor line - blocks reverse current while clamping high-side spikes. Use Value: Prevents MCU damage by limiting sensor-side voltage excursions to ≤15.6 V while allowing bidirectional DC coupling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5245BS | Same 15 V nominal, ±5 %, SOD-123, but higher rdif (150 Ω) and lower Ptot (350 mW) | Less suitable for >5 mA regulation loads or elevated ambient temperatures | Select when lower-cost qualification suffices and thermal margin is available |
| Vishay BZX84-C15 | Same 15 V, ±5 %, SOT-23 package (not SOD-123); 100 Ω rdif, 350 mW Ptot | Requires different footprint and has lower power handling; better for space-constrained boards | Select when board area is critical and 350 mW dissipation meets design requirements |
Compared with BZT52-C15J, MMBZ5245BS trades 40 % lower power rating for broader distributor availability, while BZX84-C15 offers tighter differential resistance in a smaller footprint but sacrifices 40 % thermal capacity and requires layout redesign.

FAQ
What is the Zener test current for BZT52-C15J?
The specified Zener voltage (13.8 V to 15.6 V) is measured at IZ = 5 mA, per Table 8 in the datasheet. This current establishes the operating point for regulation; deviations alter VZ due to the diode's dynamic resistance and temperature coefficient.
Can BZT52-C15J be used in automotive applications?
No - BZT52-C15J is explicitly designated as non-automotive qualified per Section 13 revision history. It lacks AEC-Q200 stress testing and is not warranted for use in safety-critical or vehicle subsystems. Automotive alternatives require the "-Q" suffix (e.g., BZT52-C15J-Q).
How does the cathode marking appear on the SOD123 package?
A single dark band on the body identifies Pin 1 (cathode), aligned with the graphic symbol in Figure 11. The marking code "CL" is laser-etched adjacent to the band, confirming type BZT52-C15 per Table 4 - no polarity ambiguity exists in correct orientation.
What is the maximum allowable ambient temperature at full power?
At full 590 mW dissipation, ambient temperature must not exceed 25 °C (per Table 5 limiting values). Above 25 °C, derating applies: for example, at 70 °C ambient, max power drops to ~350 mW using Rth(j-a) = 350 K/W from Table 6.
