Product details
Overview
HPZR-C3V6-QX from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, designed for precision low-current regulation at nominal 3.6 V with ±5 % tolerance, 5.5 W DC power dissipation at Tsp = 75 °C, and 30 kV ESD rating per IEC 61000-4-2 (contact discharge), used in automotive body control modules for sensor biasing and microcontroller I/O protection.
For engineers reviewing the HPZR-C3V6-QX datasheet, HPZR-C3V6-QX pinout, HPZR-C3V6-QX application, or HPZR-C3V6-QX equivalent, this page delivers verified electrical parameters, thermal performance under PCB mounting conditions, AEC-Q101 qualification status, and real-world use cases in automotive power rail stabilization and transient suppression.
Technical Context
This device operates as a two-terminal reverse-biased Zener diode with a nominal working voltage of 3.6 V (min 3.40 V, max 3.80 V at IZ = 100 mA), differential resistance ≤ 8.0 Ω, and reverse current ≤ 16 µA at VR = 3.0 V. Its thermal design supports junction-to-solder-point resistance of 18 K/W when mounted on cathode tab.
It delivers non-repetitive peak power dissipation up to 800 W (tp ≤ 100 µs), forward voltage ≤ 1.0 V at IF = 100 mA, and total power dissipation of 5500 mW at solder point temperature ≤ 75 °C with zero lead length measurement condition.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V6 | 300 mW Ptot, SOT23 package, RZ = 90 Ω @ IZ = 5 mA | Limited to low-power signal-level regulation; unsuitable for >100 mA continuous loads | Select when board space is constrained and power demand is <300 mW |
| MMSZ5226B | 500 mW Ptot, SOD-123 package, VZ = 3.3 V ±5 %, RZ = 28 Ω @ IZ = 20 mA | Lower voltage and power rating; lacks AEC-Q101 qualification and 30 kV ESD rating | Choose only for non-automotive consumer applications with relaxed reliability requirements |

FAQ
What is the maximum continuous reverse current HPZR-C3V6-QX can regulate at 75 °C solder point temperature?
At Tsp = 75 °C with zero lead length measurement, HPZR-C3V6-QX supports up to 1540 mA continuous reverse current (calculated from Ptot = 5500 mW ÷ VZ = 3.6 V), confirmed by Nexperia's thermal characterization in Table 8 and Figure 9 of the Rev. 6 datasheet.
Does HPZR-C3V6-QX require a heatsink for operation at full 5.5 W power dissipation?
No external heatsink is required: the CFP3 package achieves Rth(j-sp) = 18 K/W when soldered to a 1 cm² cathode pad on FR4 PCB, limiting junction temperature rise to ~100 K above solder point - well within the 175 °C absolute maximum Tj rating.
How does the 30 kV ESD rating translate to real-world board-level protection?
The 30 kV rating is measured per IEC 61000-4-2 contact discharge directly at the cathode solder point, meaning HPZR-C3V6-QX clamps ESD transients before they reach sensitive ICs - eliminating need for additional TVS diodes in many automotive I/O protection designs.
Can HPZR-C3V6-QX be used in parallel for higher current capability?
No - Zener diodes exhibit negative temperature coefficient and mismatched VZ tolerances; paralleling causes current hogging and thermal runaway. For higher current, use a single higher-power device or active regulation instead.
