Product details
Overview
HZC3.6TRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for surge absorption in low-power signal and power rail protection circuits. It delivers a nominal Zener voltage of 3.6 V (min 3.4 V, max 3.8 V) at 5 mA, with 10 µA maximum reverse leakage at 1.0 V, 130 Ω dynamic resistance, 150 mW power dissipation, and ESD capability of ±30 kV (HBM, C = 150 pF, R = 330 Ω).
For engineers reviewing the HZC3.6TRF-E datasheet, HZC3.6TRF-E pinout, HZC3.6TRF-E application, or HZC3.6TRF-E equivalent, key selection criteria include its ultra-small UFP package (SC-79), temperature coefficient of +0.03 %/°C near 3.6 V, junction temperature rating up to 150°C, and suitability for space-constrained I/O line protection in consumer and industrial electronics.
Technical Context
The HZC3.6TRF-E operates as a precision voltage reference and transient suppressor in low-energy clamping applications. Its planar epitaxial construction ensures stable Zener breakdown characteristics with tight voltage tolerance (±0.2 V at 25°C) and predictable temperature drift behavior across −55°C to +150°C ambient range.
Designed for surface-mount use in high-density PCB layouts, it leverages the Ultra Small Flat Lead Package (UFP, JEITA code PWSF0002ZA-A, SC-79 footprint) with cathode-marked anisotropic termination. The device is rated for 150 mW at 25°C, derating linearly to zero at 150°C per Fig.2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.4 V min / 3.8 V max at IZ = 5 mA - defines clamping threshold for 3.3 V logic rail protection |
| Reverse Leakage (IR) | ≤10 µA at VR = 1.0 V - ensures minimal standby current in always-on interfaces |
| Dynamic Resistance (rd) | 130 Ω max at IZ = 5 mA - determines voltage deviation under transient current surges |
| Power Dissipation (Pd) | 150 mW at Ta = 25°C - sets maximum continuous clamping energy before thermal shutdown |

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 (±5%), 200 mW Pd, SOT-23 package (2.9 × 1.3 × 1.0 mm) | Larger footprint; higher power allows longer surge duration but requires more board area | Select when higher energy handling (>150 mW) is required and PCB space permits SOT-23 |
| BZX384-C3V6 (Nexperia) | Zener voltage 3.6 V (±5%), 300 mW Pd, SOD-323 package (1.7 × 1.25 × 0.95 mm) | Same footprint width/length but 0.35 mm taller; higher Pd enables better thermal margin in sealed housings | Select when extended thermal reliability at 85°C ambient is critical and height clearance ≥0.95 mm is available |
Compared with MMBZ5226BS-7-F and BZX384-C3V6, the HZC3.6TRF-E offers the smallest installed volume (1.02 mm³) and tightest voltage tolerance (±0.2 V vs. ±5%), making it optimal for miniaturized 3.3 V interface protection where layout density and clamping precision are prioritized over peak surge energy.

FAQ
What is the Zener voltage tolerance of HZC3.6TRF-E at 25°C?
The HZC3.6TRF-E has a Zener voltage range of 3.4 V minimum to 3.8 V maximum at IZ = 5 mA and Ta = 25°C, corresponding to a ±0.2 V absolute tolerance. This tight specification eliminates the need for binning or post-layout calibration in 3.3 V rail protection designs, and is confirmed in the "Electrical Characteristics" table on page 2 of the Renesas datasheet REJ03G1204-0200 Rev.2.00.
Is HZC3.6TRF-E suitable for bidirectional ESD protection?
No - the HZC3.6TRF-E is a unidirectional Zener diode configured for cathode-to-rail clamping. For bidirectional protection (e.g., USB data lines), two HZC3.6TRF-E devices must be used in series opposition (anode-to-anode), or a dedicated bidirectional TVS like the ESD9X3.3S should be selected. The device's specified ESD capability (±30 kV HBM) applies only to the forward-biased cathode configuration.
What is the thermal derating behavior of HZC3.6TRF-E above 25°C?
HZC3.6TRF-E derates linearly from 150 mW at 25°C to 0 mW at 150°C, as shown in Fig.2 ("Power Dissipation vs. Ambient Temperature") on page 4 of the datasheet. This yields a derating factor of 1.25 mW/°C above 25°C. At 85°C ambient, the usable power dissipation is reduced to 75 mW, which corresponds to ~19.7 mA of sustained Zener current before thermal runaway.
Does HZC3.6TRF-E meet RoHS and lead-free requirements?
Yes - HZC3.6TRF-E is RoHS-compliant and lead-free, as confirmed by Renesas' environmental compliance documentation and the "Lead-Free Product" marking on the product reel label. The device uses matte tin plating on terminals and complies with EU Directive 2011/65/EU, with no exemptions applied. Full material declarations are available upon request from Aetrix Electronics.
Can HZC3.6TRF-E replace a 3.3 V Zener in existing designs?
Not directly - the HZC3.6TRF-E is specified at 3.6 V nominal (3.4–3.8 V), not 3.3 V. Substituting it for a true 3.3 V Zener (e.g., BZX384-C3V3) may cause over-clamping in 3.3 V systems, risking logic threshold violations. Verify compatibility by checking whether the protected circuit's absolute maximum input voltage exceeds 3.8 V; if not, a 3.3 V variant such as HZC3.3TRF-E should be used instead.
