Product details

Overview

CRY82(TE85L,Q,M) from Toshiba is a silicon epitaxial Zener diode designed for voltage regulation and surge absorption in compact surface-mount applications. It delivers a nominal Zener voltage of 8.2 V (min 7.4 V, max 9.0 V) at 10 mA test current, with 30 Ω typical Zener impedance, 0.7 W power dissipation, and operates across −40 to 150 °C junction temperature range - commonly used in power supply feedback loops and overvoltage protection circuits.

For engineers reviewing the CRY82(TE85L,Q,M) datasheet, CRY82(TE85L,Q,M) pinout, CRY82(TE85L,Q,M) application, or CRY82(TE85L,Q,M) equivalent, key selection criteria include verified Zener voltage tolerance, thermal derating behavior at elevated ambient temperatures, reverse leakage under specified VR, forward voltage drop at 0.2 A, and compatibility with S-FLAT™ land pattern 3-2A1S for reliable reflow soldering in space-constrained PCB layouts.

Technical Context

This Zener diode operates in reverse-biased breakdown mode to maintain stable reference voltage under varying load and line conditions. Its 8.2 V nominal Zener voltage is specified at 10 mA test current, with ±0.8 V total tolerance (7.4–9.0 V), and exhibits a temperature coefficient α_T of +3.0 mV/°C (typical), indicating positive drift with rising temperature.

The device uses Toshiba's S-FLAT™ package - a small-outline surface-mount structure with cathode marking and 0.013 g typical weight - optimized for low thermal resistance when mounted on 6 mm × 6 mm copper land on FR-4. Its non-repetitive peak reverse power dissipation (PRSM) supports transient surge suppression up to 42 W for 1 ms pulses.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage V_Z	7.4–9.0 V at I_Z = 10 mA - defines usable regulation window for feedback or clamping
Zener Impedance r_d	30 Ω (typ.) - determines output voltage variation under load current changes
Power Dissipation P	0.7 W (T_a = 25°C) - sets maximum continuous DC power before thermal derating applies
Reverse Current I_R	10 μA max at V_R = 4.9 V - ensures low leakage in standby or high-impedance bias networks
Forward Voltage V_F	1.0 V max at I_F = 0.2 A - enables use as low-drop rectifier or clamp in bidirectional protection
Junction Temperature T_j	−40 to +150 °C - confirms suitability for industrial and automotive under-hood environments
Temperature Coefficient α_T	+3.0 mV/°C (typ.) - quantifies voltage drift per degree, critical for precision references

Pinout & Package

CRY82(TE85L,Q,M) is housed in Toshiba's S-FLAT™ package (JEITA package code 3-2A1S), a two-terminal surface-mount device with cathode marked by a band. The package measures 2.8 × 1.2 × 1.2 mm and weighs 0.013 g (typ.). Land pattern follows Toshiba reference dimensions (6 mm × 6 mm copper pad recommended on FR-4).

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward conduction terminal / low-side connection in Zener configuration	Connected to lower potential node; carries forward current or sinks reverse leakage

Key Features

Feature	Design Value
Compact S-FLAT™ package	Enables high-density PCB layout with 2.8 mm length and 1.2 mm height - ideal for space-limited power modules
Low Zener impedance	30 Ω typical ensures <±50 mV output shift under ±1.5 mA load variation - improves regulation accuracy
Controlled temperature coefficient	+3.0 mV/°C typical allows predictable drift compensation in temperature-stable references
High surge absorption capability	Supports 42 W non-repetitive PRSM at 1 ms - protects downstream circuitry from ESD and line transients
Wide operating temperature range	−40 to +150 °C junction rating permits use in industrial motor drives and automotive body control units

Applications

Switch-Mode Power Supply Feedback	Overvoltage Clamp for Microcontroller I/O
Use Scenario: Regulating output voltage in isolated flyback or buck-boost converters via optocoupler-coupled feedback loop.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MMBZ5231BS-7-F (Diodes Inc.)	8.2 V nominal, 30 Ω Z_Z, 0.35 W P_D, SOT-23 package	Lower power rating limits use in higher-current regulation; smaller footprint but higher thermal resistance	Select when board space is constrained and average power ≤ 0.35 W; verify thermal margin on 2-layer boards
BZX84-C8V2 (Nexperia)	8.2 V nominal, 30 Ω Z_Z, 0.365 W P_D, SOT-23 package	Limited to lower-power clamping due to reduced dissipation; identical voltage spec but tighter 5% tolerance (7.79–8.61 V)	Prefer for cost-sensitive consumer designs where 0.365 W suffices and tighter V_Z tolerance is acceptable

Compared with MMBZ5231BS-7-F and BZX84-C8V2, CRY82(TE85L,Q,M) offers 0.7 W power handling - nearly double - enabling robust regulation in industrial power supplies without external heatsinking, while maintaining matching Zener impedance and voltage centering.

FAQ

What is the Zener voltage tolerance of CRY82(TE85L,Q,M) at 25°C?

CRY82(TE85L,Q,M) has a Zener voltage range of 7.4 V (minimum) to 9.0 V (maximum) at I_Z = 10 mA and T_a = 25°C, yielding a total tolerance of ±0.8 V around the nominal 8.2 V value. This specification is confirmed in Toshiba's official CRY62–CRZ39 datasheet, page 2, Electrical Characteristics table.

Does CRY82(TE85L,Q,M) support surge protection applications?

Yes, CRY82(TE85L,Q,M) is explicitly designated as a "surge absorber" in Toshiba's documentation. Its non-repetitive peak reverse power dissipation (PRSM) reaches 42 W for 1 ms pulses, validated in the PRSM–t_W graph on page 4 of the datasheet - making it suitable for transient voltage suppression in DC power rails and interface lines.

What is the recommended land pattern for CRY82(TE85L,Q,M)?

Toshiba specifies land pattern 3-2A1S for CRY82(TE85L,Q,M), recommending a 6 mm × 6 mm copper pad on FR-4 for optimal thermal performance. This layout achieves lower junction-to-ambient thermal resistance, supporting full 0.7 W dissipation at T_a = 25°C - details appear in the Land Pattern Dimensions section on page 1 of the datasheet.

Is CRY82(TE85L,Q,M) RoHS compliant?

Yes, CRY82(TE85L,Q,M) complies with the EU RoHS Directive. Toshiba confirms RoHS compatibility for the CRY/CRZ series in its environmental compliance documentation, and the device contains no lead, mercury, cadmium, hexavalent chromium, PBB, or PBDE above threshold limits - consistent with standard S-FLAT™ manufacturing.

What is the forward voltage drop of CRY82(TE85L,Q,M) at rated current?

CRY82(TE85L,Q,M) exhibits a maximum forward voltage (V_F) of 1.0 V at a forward current (I_F) of 0.2 A, as specified in the Electrical Characteristics table on page 2 of the Toshiba datasheet. This enables bidirectional clamping functionality - conducting below 1 V in forward bias and regulating near 8.2 V in reverse.
