Toshiba Semiconductor and Storage CRY62(TE85L,Q,M)

Overview

CRY62(TE85L,Q,M) from Toshiba is a silicon epitaxial Zener diode designed for voltage regulation and surge absorption in compact SMT power management circuits, with nominal Zener voltage 6.2 V (min 5.6 V, typ 6.2 V, max 6.8 V), 10 mA test current, 60 Ω typical Zener impedance, 1.0 V forward voltage at 0.2 A, and 10 μA reverse leakage at 3.0 V.

For engineers reviewing the CRY62(TE85L,Q,M) datasheet, CRY62(TE85L,Q,M) pinout, CRY62(TE85L,Q,M) application, or CRY62(TE85L,Q,M) equivalent, key selection criteria include Zener voltage tolerance, thermal coefficient (−2 mV/°C typ), junction temperature range (−40 to 150°C), S-FLAT™ package footprint compatibility, and pulse power handling per PRSM–t_W curve.

Technical Context

CRY62(TE85L,Q,M) operates as a precision shunt regulator with fixed breakdown voltage defined under 10 mA DC test conditions. Its low dynamic impedance (60 Ω max) ensures stable regulation under varying load currents, while its negative temperature coefficient (−2 mV/°C typ) enables predictable drift compensation in temperature-sensitive references.

The device uses Toshiba's S-FLAT™ surface-mount package (JEITA 3-2A1S), optimized for thermal dissipation on standard FR-4 PCBs with 6 mm × 6 mm copper land. It supports non-repetitive surge absorption up to 46 W (t_W = 1 ms) and continuous power dissipation of 0.7 W at T_a = 25°C.

FAQ

What is the Zener voltage tolerance of CRY62(TE85L,Q,M) at 10 mA test current?

CRY62(TE85L,Q,M) has a Zener voltage range of 5.6 V (min) to 6.8 V (max) at I_Z = 10 mA, corresponding to ±10% tolerance around the nominal 6.2 V rating. This tolerance is fully specified in Toshiba's official Electrical Characteristics table and applies under standard Ta = 25°C conditions. Designers must account for this spread when setting feedback divider ratios in regulated power supplies using CRY62(TE85L,Q,M).

Does CRY62(TE85L,Q,M) support surge protection, and what is its peak pulse rating?

Yes, CRY62(TE85L,Q,M) is explicitly rated as a surge absorber. Its non-repetitive peak reverse power dissipation (PRSM) is 46 W for a 1 ms pulse width, as confirmed in Toshiba's PRSM–t_W graph. This capability enables CRY62(TE85L,Q,M) to safely clamp transient overvoltages in automotive and industrial environments without degradation, provided pulse repetition remains infrequent and thermal recovery time is observed.

What is the thermal resistance profile of CRY62(TE85L,Q,M), and how does it affect PCB layout?

CRY62(TE85L,Q,M) exhibits transient thermal impedance r_th(j-a) = 100°C/W at t = 0.01 s when mounted on a glass-epoxy board with 6 mm × 6 mm solder land. This value drops to ~30°C/W at steady state. To maintain T_j ≤ 120°C under 0.7 W dissipation, designers must use ≥6 mm × 6 mm copper pads and avoid thermal isolation - a critical requirement reflected in CRY62(TE85L,Q,M)'s recommended land pattern dimensions.

Is CRY62(TE85L,Q,M) RoHS compliant, and what is its lead-free status?

CRY62(TE85L,Q,M) complies with EU RoHS Directive 2011/65/EU. Toshiba confirms lead-free termination and halogen-free packaging for this part, as documented in their environmental compliance reports. The "Q" suffix in CRY62(TE85L,Q,M) denotes RoHS-compliant processing, and material declarations are available upon request through Aetrix Electronics' technical support for CRY62(TE85L,Q,M).

How does the temperature coefficient of CRY62(TE85L,Q,M) impact voltage reference stability?

CRY62(TE85L,Q,M) has a typical temperature coefficient α_T of −2 mV/°C, meaning its Zener voltage decreases by ~2 mV per degree Celsius rise. Over a −40 to +85°C range, this results in ~250 mV total drift. For stable references, designers pair CRY62(TE85L,Q,M) with positive-tempco components (e.g., silicon diodes) to achieve net zero-drift bias networks - a technique validated in Toshiba's application notes for CRY62(TE85L,Q,M) reference designs.
