Product details
Overview
HZC36JTRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for transient voltage suppression and surge absorption in low-power signal-line protection circuits. It delivers a nominal Zener voltage of 36 V (min 34.0 V, max 38.0 V) at 2 mA, with dynamic resistance of 90 Ω, 20 kV ESD capability (IEC 61000-4-2), and 150 mW power dissipation in an ultra-small UFP package - used in USB data lines, sensor interfaces, and microcontroller I/O protection.
For engineers reviewing the HZC36JTRF-E datasheet, HZC36JTRF-E pinout, HZC36JTRF-E application, or HZC36JTRF-E equivalent, key selection criteria include its 36 V Zener tolerance (±5.6%), low leakage (<0.5 µA at 27 V), temperature coefficient of +0.07 %/°C, surface-mount UFP footprint (1.7 × 1.2 × 0.6 mm), and suitability for space-constrained consumer and industrial electronics requiring robust electrostatic discharge immunity.
Technical Context
The HZC36JTRF-E operates as a precision voltage reference and clamping device in reverse-biased configuration, leveraging epitaxial planar junction technology to achieve stable breakdown characteristics across −55°C to +150°C ambient range. Its design targets low-capacitance transient suppression without compromising response speed or thermal stability.
It is rated for 2 mA Zener test current and exhibits a positive temperature coefficient (+0.07 %/°C), making it suitable for applications where voltage drift must remain predictable under thermal variation - unlike negative-coefficient Zeners used in temperature-compensated references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 34.0 V to 38.0 V at IZ = 2 mA - defines clamping threshold for overvoltage events on protected lines |
| Dynamic Resistance (rd) | 90 Ω max at IZ = 2 mA - determines voltage rise under surge current; lower rd improves clamping accuracy |
| Reverse Leakage (IR) | ≤0.5 µA at VR = 27 V - ensures minimal standby power loss and signal integrity in high-impedance circuits |
| ESD Capability | ±20 kV per IEC 61000-4-2 (contact), ±30 kV (air) - provides system-level ESD immunity without external TVS staging |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - sets maximum continuous surge energy handling before thermal derating begins |
| Temperature Coefficient | +0.07 %/°C - enables predictable voltage drift up to +125°C, supporting stable operation in automotive cabin modules |
| Junction Temperature (Tj) | 150°C max - allows use in sealed enclosures or near heat-generating components without derating penalties |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode surge absorption applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C36 (Nexperia) | Same 36 V nominal Zener, but 350 mW Pd, larger SOD-323 package (1.7 × 1.3 × 0.9 mm), higher leakage (≤5 µA at 28.8 V) | Preferred where higher surge energy handling is required; less suitable for ultra-dense layouts | Select BZX584-C36 when board space allows and peak pulse power exceeds 150 mW limits of HZC36JTRF-E |
| MMBZ5241BLT1G (onsemi) | 36 V Zener, SOT-23 package (3.0 × 1.4 × 1.0 mm), 225 mW Pd, 100 Ω rd, ±5% tolerance | Offers higher power rating and wider availability, but larger footprint increases trace inductance in RF-sensitive designs | Choose MMBZ5241BLT1G for legacy SOT-23 assembly lines or where tighter 5% voltage tolerance is mandatory |
Compared with BZX584-C36 and MMBZ5241BLT1G, the HZC36JTRF-E provides the smallest footprint and lowest leakage among 36 V Zener surge suppressors, making it optimal for miniaturized portable electronics and high-density PCBs where ESD robustness and space efficiency are jointly critical.

FAQ
What is the Zener voltage tolerance of HZC36JTRF-E?
The HZC36JTRF-E has a specified Zener voltage range of 34.0 V to 38.0 V at 2 mA test current, corresponding to ±5.6% tolerance around the nominal 36 V value. This tolerance is verified per Renesas' REJ03G1204-0200 datasheet Rev. 2.00 and reflects production lot consistency under standard test conditions (Ta = 25°C, pulsed measurement).
Does HZC36JTRF-E meet IEC 61000-4-2 ESD standards?
Yes, the HZC36JTRF-E is rated for ±20 kV contact discharge and ±30 kV air discharge per IEC 61000-4-2, as confirmed in the "Electrical Characteristics" table of its official datasheet. This performance is achieved without external circuitry and applies to both forward and reverse polarity pulses using the standard 150 pF/330 Ω network.
What is the thermal derating behavior of HZC36JTRF-E above 25°C?
The HZC36JTRF-E follows linear thermal derating: its 150 mW power dissipation rating decreases by 1.2 mW/°C above 25°C ambient, reaching zero at 150°C junction temperature. This curve is defined in Figure 2 ("Power Dissipation vs. Ambient Temperature") of the datasheet and assumes standard FR-4 PCB mounting with minimal copper area.
Is HZC36JTRF-E compatible with lead-free reflow soldering processes?
Yes, the HZC36JTRF-E is qualified for lead-free reflow per J-STD-020, supporting peak temperatures up to 260°C for 10 seconds. Its UFP package uses matte tin plating and complies with RoHS Directive 2011/65/EU, with no exemptions required for lead content.
How does the temperature coefficient affect HZC36JTRF-E's clamping voltage in automotive applications?
The HZC36JTRF-E exhibits a +0.07 %/°C temperature coefficient, meaning its Zener voltage increases by approximately 25 mV/°C near room temperature. At 105°C (typical under-hood condition), clamping rises to ~37.5 V - still within safe margin for 36 V-rated systems and avoids false triggering in body control modules.
