Product details
Overview
HZC3.6JTRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for surge absorption in low-power signal-line protection circuits, featuring a nominal Zener voltage of 3.6 V (3.4–3.8 V), 150 mW power dissipation, and ultra-small UFP (SC-79) surface-mount package. It delivers 10 µA maximum reverse current at 1.0 V, 130 Ω dynamic resistance at 5 mA, and ±30 kV ESD capability per IEC 61000-4-2 (C = 150 pF, R = 330 Ω).
For engineers reviewing the HZC3.6JTRF-E datasheet, HZC3.6JTRF-E pinout, HZC3.6JTRF-E application, or HZC3.6JTRF-E equivalent, key selection criteria include precise 3.6 V clamping tolerance, thermal stability across −55°C to +150°C, SC-79 footprint compatibility, and verified ESD robustness in USB, audio I/O, and sensor interface protection.
Technical Context
This device operates as a voltage-reference clamp in transient suppression circuits, leveraging epitaxial planar junction technology for tight Zener voltage distribution and stable temperature coefficient (−0.02 to +0.05 %/°C typical for 3.6 V grade). Its low dynamic impedance ensures rapid response to fast-rising ESD pulses without overshoot beyond the rated clamping voltage.
The HZC3.6JTRF-E is designed for DC-biased signal lines where low leakage (<10 µA at 1.0 V) and minimal capacitance (not specified but consistent with SC-79 geometry) preserve signal integrity. It is not intended for high-energy surge events-its 150 mW Pd rating limits use to Class 1–2 IEC 61000-4-2 applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.4–3.8 V at IZ = 5 mA - defines precise clamping threshold for 3.3 V logic rail protection |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - sets maximum continuous power handling before thermal derating |
| Reverse Current (IR) | ≤10 µA at VR = 1.0 V - ensures negligible standby leakage in battery-powered interfaces |
| Dynamic Resistance (rd) | 130 Ω at IZ = 5 mA - determines voltage rise under transient current, critical for clamping accuracy |
| ESD Capability | ±30 kV (contact), ±30 kV (air), per IEC 61000-4-2 - qualifies for highest-level system-level ESD immunity testing |
| Junction Temperature (Tj) | 150°C maximum - enables operation in thermally constrained PCB layouts near processors or power ICs |
| Package | UFP (SC-79) - 1.7 × 1.2 × 0.6 mm footprint supports high-density routing and automated placement |

| Low 10 µA reverse leakage at 1.0 V | Preserves signal integrity and battery life in always-on sensor nodes and portable audio interfaces |
| 150°C max junction temperature | Allows reliable operation in sealed enclosures or near heat-generating components like PMICs or DC-DC converters |
Applications
| USB 2.0 Data Line Protection | Audio Jack ESD Suppression |

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 |
|---|---|---|---|
| MMBZ5226BS-7-F (Diodes Inc.) | Zener voltage 3.3 V (3.1–3.5 V), 200 mW Pd, SOT-23 package (2.9 × 1.3 × 1.0 mm) | Larger footprint increases trace inductance; higher Pd allows margin for longer transients | Choose when board space permits larger package and higher energy handling is required |
| BZX584-C3V6 (Nexperia) | Zener voltage 3.6 V (3.42–3.78 V), 300 mW Pd, SOD-323 (1.7 × 1.3 × 0.9 mm) | Same voltage tolerance, but 2× Pd rating and 50% higher height - may conflict with low-profile shields | Prefer for designs needing extended surge duration immunity without layout change |
Compared with HZC3.6JTRF-E, MMBZ5226BS-7-F offers higher power but requires PCB real estate rework, while BZX584-C3V6 matches voltage spec closely but adds 0.3 mm height-critical in ultra-thin consumer enclosures.

FAQ
What is the exact Zener voltage range for HZC3.6JTRF-E at 5 mA test current?
The HZC3.6JTRF-E has a guaranteed Zener voltage range of 3.40 V to 3.80 V when tested at IZ = 5 mA and Ta = 25°C, per Renesas datasheet REJ03G1204-0200 Rev. 2.00. This 400 mV window ensures predictable clamping behavior for 3.3 V system rails without risking under-clamping or excessive forward conduction.
Does HZC3.6JTRF-E meet IEC 61000-4-2 Level 4 ESD immunity?
Yes, HZC3.6JTRF-E is rated for ±30 kV contact and ±30 kV air discharge per IEC 61000-4-2, exceeding Level 4 (±8 kV contact / ±15 kV air). The test uses C = 150 pF and R = 330 Ω, with failure defined per IR specification-making HZC3.6JTRF-E suitable for end-equipment certification without supplemental protection.
What is the thermal derating behavior of HZC3.6JTRF-E above 25°C ambient?
HZC3.6JTRF-E follows linear thermal derating from 150 mW at 25°C down to 0 mW at 150°C ambient, as shown in Figure 2 of the datasheet. At 85°C ambient, its usable power dissipation drops to approximately 90 mW-requiring layout attention to copper area and airflow in enclosed designs.
Can HZC3.6JTRF-E be used in bidirectional ESD protection configurations?
No-HZC3.6JTRF-E is a unidirectional Zener diode with anode and cathode terminals explicitly defined (Pin 1 = cathode, Pin 2 = anode). For bidirectional protection, two HZC3.6JTRF-E devices must be connected in series opposition, or a dedicated bidirectional TVS like the ESD9X3.3S should be selected instead.
Is HZC3.6JTRF-E compliant with RoHS and REACH regulations?
Yes, HZC3.6JTRF-E is RoHS-compliant (lead-free, homogeneous material level) and meets REACH SVHC requirements, as confirmed by Renesas' environmental compliance documentation. The "-E" suffix in the part number denotes lead-free termination, and the UFP package contains no exempted substances above threshold limits.
