Product details
Overview
HZC7.5JTRF-E from Renesas Electronics is a silicon epitaxial planar Zener diode optimized for surge absorption in low-power signal and power rail protection circuits, with a nominal Zener voltage of 7.5 V (7.06–7.84 V), 150 mW power dissipation, 30 kV ESD capability (IEC 61000-4-2), and housed in an ultra-small Flat Lead Package (UFP, SC-79). It serves as a precision clamping device in USB interface lines, microcontroller I/O protection, and sensor signal conditioning.
For engineers reviewing the HZC7.5JTRF-E datasheet, HZC7.5JTRF-E pinout, HZC7.5JTRF-E application, or HZC7.5JTRF-E equivalent, key selection criteria include Zener voltage tolerance (±5.2%), dynamic resistance (≤30 Ω at 5 mA), temperature coefficient (≈+0.05 %/°C), junction temperature limit (150°C), and UFP package compatibility with high-density SMT layouts.
Technical Context
The HZC7.5JTRF-E operates as a two-terminal voltage reference and transient suppressor, leveraging silicon epitaxial planar construction for stable reverse breakdown behavior under pulsed surge conditions. Its design targets low-energy ESD events and fast-rising transients rather than high-energy lightning surges.
It exhibits a positive temperature coefficient (~+0.05 %/°C) near 7.5 V, enabling predictable voltage drift over −55°C to +150°C ambient range. The device is rated for 5 mA test current and maintains ≤30 Ω dynamic impedance up to its 150 mW thermal limit, supporting reliable clamping in battery-powered and low-voltage logic interfaces.
Key Specifications

Applications
| USB 2.0 Data Line Protection | Microcontroller GPIO Clamp |
|---|---|
Use Scenario: Protecting D+ and D− lines of embedded USB peripherals against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed between data line and local ground plane.

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 |
|---|---|---|---|
| MMBZ5231BS-7-F | Zener voltage 5.1 V ±5%, 200 mW Pd, SOD-323 package (1.7 × 1.3 × 0.9 mm) | Lower clamping voltage; better suited for 3.3 V rail protection than 5 V or mixed-voltage systems | Select when tighter 5.1 V threshold and higher power margin are required, accepting larger footprint and slightly higher leakage. |
| BZX384-B7V5,115 | Zener voltage 7.5 V ±5%, 300 mW Pd, SOD-323 package, ±2.5 mV/°C tempco | Higher power rating allows longer surge duration handling; wider tempco may affect accuracy over wide temperature ranges | Choose for applications needing extended surge energy absorption beyond 150 mW, such as industrial control I/O modules. |
Compared with HZC7.5JTRF-E, MMBZ5231BS-7-F offers lower clamping but less voltage headroom for 5 V systems, while BZX384-B7V5,115 provides double the power rating at the cost of reduced thermal stability-making HZC7.5JTRF-E optimal for compact, thermally constrained 7.5 V clamping where precision and size are prioritized.

FAQ
What is the Zener voltage tolerance of HZC7.5JTRF-E?
The HZC7.5JTRF-E has a Zener voltage range of 7.06 V to 7.84 V at 5 mA test current, corresponding to a ±5.2% tolerance about the nominal 7.5 V rating. This tolerance is confirmed in the Renesas HZC Series datasheet Rev.2.00 (Jul 2005), page 2, Electrical Characteristics table. The specification ensures predictable clamping behavior across manufacturing lots and temperature extremes.
Is HZC7.5JTRF-E suitable for protecting 5 V logic lines?
Yes, HZC7.5JTRF-E is appropriate for 5 V logic line protection because its minimum Zener voltage (7.06 V) provides sufficient margin above the 5 V rail to avoid false triggering during normal operation, while its maximum clamping voltage (7.84 V) remains safely below typical 8 V absolute maximum ratings of 5 V-tolerant I/O cells. Its 30 kV ESD rating and low dynamic resistance ensure effective transient suppression without signal distortion.
What is the package type and dimensions of HZC7.5JTRF-E?
HZC7.5JTRF-E uses the Ultra-small Flat Lead Package (UFP), identical to JEDEC SC-79, with dimensions of 1.7 mm × 1.2 mm × 0.6 mm and a mass of 0.0016 g. Pin 1 is cathode (marked), Pin 2 is anode. This information is specified in the Renesas HZC Series datasheet Rev.2.00, page 5, Package Dimensions table and ordering information section.
Does HZC7.5JTRF-E meet RoHS requirements?
Yes, HZC7.5JTRF-E complies with the EU RoHS Directive, as confirmed by Renesas Electronics' environmental compliance documentation and product marking. The device contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE) above threshold limits. Customers should verify latest status via Renesas' official environmental reports or Aetrix's material declarations.
What is the maximum junction temperature rating for HZC7.5JTRF-E?
The maximum junction temperature (Tj) for HZC7.5JTRF-E is 150°C, as stated in the Absolute Maximum Ratings table on page 2 of the Renesas HZC Series datasheet Rev.2.00. This rating applies under steady-state conditions with proper PCB thermal relief and defines the upper thermal boundary for reliable long-term operation without parametric shift or premature failure.
