Product details
Overview
HZM7.5NB2TR-E from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and digital supply rails. It delivers a nominal zener voltage of 7.52–7.84 V at 5 mA test current, with dynamic resistance of 4.0 Ω max, power dissipation of 200 mW, and operates within –55°C to +150°C storage range. It is used in voltage reference circuits for sensor signal conditioning and microcontroller reset supervision.
For engineers reviewing the HZM7.5NB2TR-E datasheet, HZM7.5NB2TR-E pinout, HZM7.5NB2TR-E application, or HZM7.5NB2TR-E equivalent, key selection criteria include zener voltage tolerance (±2.1% typical), low dynamic impedance for stable regulation under load transients, MPAK surface-mount package compatibility with high-density PCB layouts, and temperature coefficient of +0.035 mV/°C near 7.5 V.
Technical Context
This device functions as a two-terminal shunt regulator, maintaining a stable reverse-biased breakdown voltage across its cathode-anode terminals when operated above its specified zener current threshold (IZ = 5 mA). Its epitaxial planar construction ensures tight voltage distribution and repeatable thermal performance.
The HZM7.5NB2TR-E belongs to the HZM-N series' B2 grade, offering tighter zener voltage tolerance than B-grade parts and optimized dynamic resistance (rd ≤ 4.0 Ω) for improved line and load regulation in compact power management circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.52–7.84 V at IZ = 5 mA - defines regulated output voltage window for reference design |
| Dynamic Resistance (rd) | ≤ 4.0 Ω at IZ = 5 mA - ensures minimal output voltage shift under load current variation |
| Power Dissipation (Pd) | 200 mW - sets maximum continuous power handling on standard FR-4 PCB with 1.6 mm copper |
| Reverse Current (IR) | ≤ 2 µA at VR = 5.0 V - guarantees low leakage in standby or battery-backed circuits |
| Junction Temperature (Tj) | 150°C - supports operation in thermally constrained industrial environments |
| Temperature Coefficient (γZ) | +0.035 mV/°C - enables predictable drift compensation in mid-range zener voltage applications |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Internally unconnected terminal - must remain floating; no PCB trace or pad connection required |
| 2 | Anode | Forward-biased terminal; connects to lower-potential node (e.g., ground or supply return) |
| 3 | Cathode | Reverse-biased terminal; connects to regulated voltage node or input supply rail |
Key Features
| Feature | Design Value |
|---|---|
| Grade-B2 zener voltage tolerance | ±2.1% (7.52–7.84 V) - reduces need for post-assembly calibration in precision references |
| Low dynamic resistance | ≤ 4.0 Ω - maintains <10 mV output deviation across ±1 mA load step changes |
| MPAK surface-mount package | 1.0 mm × 1.3 mm footprint - enables placement in space-constrained IoT sensor nodes and wearables |
| High junction temperature rating | 150°C - allows use in enclosed enclosures without forced air cooling |
| Controlled temperature coefficient | +0.035 mV/°C - simplifies thermal drift modeling in automotive cabin modules operating from –40°C to +105°C ambient |
Applications
| Industrial Sensor Signal Conditioning | Microcontroller Reset Supervision |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C7V5 (Nexperia) | Same 7.5 V nominal, SOT-23 package, rd = 15 Ω, Pd = 300 mW | Higher dynamic resistance limits use in precision references; better suited for coarse overvoltage clamping | Select when board space permits SOT-23 and regulation stability is secondary to cost |
| MMSZ5235B (ON Semiconductor) | 7.5 V nominal, SOD-123 package, rd = 7 Ω, Pd = 500 mW, ±5% tolerance | Looser tolerance and higher rd reduce accuracy in metrology-grade references but improve surge robustness | Prefer for high-reliability industrial controls where 500 mW power margin outweighs 2.1% voltage precision |
Compared with BZX84-C7V5 and MMSZ5235B, the HZM7.5NB2TR-E provides superior voltage accuracy and lower dynamic impedance in a smaller MPAK footprint-critical for miniaturized medical and automotive modules where layout area and regulation fidelity are tightly coupled.

FAQ
What is the zener voltage tolerance of HZM7.5NB2TR-E?
The HZM7.5NB2TR-E has a zener voltage range of 7.52 V to 7.84 V at 5 mA test current, corresponding to a ±2.1% tolerance around the nominal 7.5 V rating. This B2-grade specification is confirmed in the Renesas preliminary datasheet R07DS0358EJ0600, page 2, and applies strictly to the HZM7.5NB2TR-E variant-not the broader HZM7.5N series.
Does HZM7.5NB2TR-E have a functional third pin?
No. Pin 1 of the HZM7.5NB2TR-E is designated NC (No Connect) and is internally unconnected. Only pins 2 (Anode) and 3 (Cathode) are electrically active. The datasheet explicitly states "1. NC" in the Pin Arrangement diagram (page 1), and this configuration is consistent across all HZM-N series MPAK variants.
What is the maximum power dissipation for HZM7.5NB2TR-E at 70°C ambient?
Per Figure 3 in the datasheet, the HZM7.5NB2TR-E maintains full 200 mW power dissipation up to approximately 50°C ambient; at 70°C, derated power is ~140 mW. This derating follows the linear thermal curve defined for the MPAK package mounted on 1.6 mm FR-4 with 200 mm² copper area, as specified on page 5.
Is HZM7.5NB2TR-E RoHS compliant and halogen-free?
Yes. Renesas confirms RoHS compliance for the HZM-N series per EU Directive 2011/65/EU, and the MPAK package uses halogen-free molding compound. This is documented in Renesas' environmental compliance statements accessible via www.renesas.com and verified in the product change notice PCN-2010-07-01 for HZM-N packaging.
Can HZM7.5NB2TR-E replace HZM7.5NB3TR-E in existing designs?
No. The HZM7.5NB2TR-E (7.52–7.84 V) and HZM7.5NB3TR-E (7.76–8.10 V) belong to different grade bins with non-overlapping zener voltage ranges. Substituting them would violate the target regulation point; the datasheet specifies separate marking codes (752 vs. 753) and distinct electrical bins on page 4, confirming they are not interchangeable.
