Product details
Overview
BZT52-C5V6J from Nexperia is a ±5 % tolerance Zener diode in SOD123 package, rated for 5.6 V nominal regulation at 5 mA, with 400 Ω max differential resistance and 1 μA reverse current at 3.5 V, used for precision voltage reference and overvoltage protection in low-power analog circuits.
For engineers reviewing the BZT52-C5V6J datasheet, BZT52-C5V6J pinout, BZT52-C5V6J application, or BZT52-C5V6J equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance, thermal resistance (210 K/W junction-to-solder-point), power derating above 25 °C, and SOD123 footprint compatibility with IPC-7351B reflow land patterns.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 5.6 V output across load and supply variations, with temperature coefficient of −2.0 to +2.5 mV/K at IZ = 5 mA - enabling predictable drift compensation in bias networks. Its low 400 Ω differential resistance ensures minimal output voltage shift under ±1 mA current change.
Designed for surface-mount use on FR4 PCBs with single-sided copper, it delivers 590 mW total power dissipation at Tamb ≤ 25 °C, derating linearly to zero at 150 °C junction temperature, and supports non-repetitive 6 A surge current (100 μs pulse) for transient suppression.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.2 V to 6.0 V at IZ = 5 mA - defines regulation band for stable reference generation |
| Differential Resistance rdif | 400 Ω max - limits output voltage variation to ≤400 mV per 1 mA load change |
| Reverse Current IR | 1 μA max at VR = 3.5 V - ensures low leakage in standby bias networks |
| Total Power Dissipation Ptot | 590 mW at Tamb ≤ 25 °C - sets maximum continuous DC power before thermal shutdown |
| Junction-to-Solder-Point Rth(j-sp) | 210 K/W - determines temperature rise above PCB pad under steady-state operation |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - defines conduction loss when used as clamp in forward direction |
| Non-repetitive Peak IZSM | 6.0 A at tp = 100 μs - supports ESD/inductive spike suppression without failure |
Pinout & Package
SOD123 plastic surface-mount package: 2.80 mm × 1.70 mm body, 0.70 mm lead pitch, cathode marked by black band; optimized for reflow soldering with 0.81 mm × 2.36 mm Cu pad per JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking band identifies this terminal for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| ±5 % Zener voltage tolerance | Enables cost-effective voltage referencing where tight regulation is not required, e.g., power-on reset thresholds |
| Low 400 Ω differential resistance | Maintains <±20 mV output shift across 50–100 mA load transients in feedback divider networks |
| 210 K/W junction-to-solder-point thermal resistance | Allows 590 mW operation with only 124 °C junction rise above pad temperature on standard FR4 |
| 6.0 A non-repetitive surge rating | Clamps 100 μs inductive kickback events up to 40 W peak without degradation |
| SOD123 footprint compatibility | Matches IPC-7351B generic SMD diode land pattern, enabling drop-in replacement in high-density layouts |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBZ5232BS-7-F (Diodes Inc.) | Same 5.6 V nominal, ±5 %, but SOT-323 package (1.7 × 1.3 mm) and 350 mW Ptot | Lower power handling; unsuitable for >350 mW continuous dissipation | Select when board space is constrained and thermal load is <350 mW |
| BZX384-C5V6 (Nexperia) | Same 5.6 V, ±5 %, but SOD-323 package and 300 mW Ptot; 500 Ω rdif max | Higher impedance and lower power limit reduce regulation precision under load | Select only for ultra-low-power signal-level referencing where 500 Ω rdif is acceptable |
Compared with MMBZ5232BS-7-F and BZX384-C5V6, BZT52-C5V6J offers 67 % higher power rating and 20 % lower dynamic impedance in a widely adopted SOD123 footprint - making it optimal for general-purpose regulation where thermal margin and voltage stability are prioritized over minimal size.

FAQ
What is the maximum continuous reverse current the BZT52-C5V6J can sustain at 25 °C ambient?
The device is rated for 590 mW total power dissipation at Tamb ≤ 25 °C. At its 5.6 V Zener voltage, this corresponds to a maximum continuous reverse current of 105 mA (590 mW ÷ 5.6 V). Operation beyond this requires derating per the thermal resistance curve in the datasheet.
Can BZT52-C5V6J be used in automotive applications?
No. Per Nexperia's revision history (Rev. 2, October 2025), the C-series BZT52 devices are explicitly designated as non-automotive qualified. Automotive-grade alternatives - such as the BZT52-Q series - undergo AEC-Q101 stress testing and are documented separately on nexperia.com.
How does the 210 K/W junction-to-solder-point thermal resistance impact PCB layout?
This value means each watt of dissipated power raises the junction temperature 210 °C above the cathode solder point temperature. To keep Tj ≤ 150 °C at 590 mW, the cathode pad must remain below 37.5 °C - requiring adequate copper area (≥1 cm² per datasheet condition [3]) and minimal thermal isolation from heatsinking planes.
Is the 6.0 A non-repetitive peak reverse current tested under standardized conditions?
Yes. The 6.0 A rating is specified at tp = 100 μs, square-wave pulse, with Tj = 25 °C prior to surge (per Table 5 note [2]). It is validated per IEC 60134 absolute maximum rating methodology and reflects single-event survivability - not repetitive duty-cycle capability.
