Product details

Overview

CRH01(TE85L) from TOSHIBA is a high-efficiency, ultra-fast recovery silicon epitaxial rectifier diode rated for 200 V repetitive peak reverse voltage (V_RRM), 1 A average forward current (I_F(AV)), and 35 ns maximum reverse recovery time (t_rr). It serves as a primary output rectifier in compact AC/DC and DC/DC switching power supplies where low conduction loss and fast switching are critical.

For engineers reviewing the CRH01(TE85L) datasheet, CRH01(TE85L) pinout, CRH01(TE85L) application, or CRH01(TE85L) equivalent, key selection criteria include its 0.98 V max forward voltage at 1 A, S-FLAT™ surface-mount package footprint, thermal resistance of 65 °C/W on ceramic board, and suitability for high-frequency SMPS designs operating up to several hundred kHz.

Technical Context

This device employs a planar epitaxial construction optimized for low forward voltage and minimal minority-carrier storage, enabling ultra-fast recovery (t_rr ≤ 35 ns) with controlled softness. Its junction temperature range spans −40 °C to +150 °C, supporting operation in thermally constrained environments such as enclosed power adapters and industrial DC/DC modules.

Electrical behavior is characterized under pulse test conditions: V_FM is specified at three forward current levels (0.1 A, 0.7 A, 1 A), confirming consistent low-loss performance across load transients; I_RRM remains ≤ 10 µA at full 200 V reverse bias, ensuring minimal leakage in high-impedance hold-up stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Supports input rectification or secondary-side synchronous replacement in 12–24 V output SMPS with ≥2× safety margin against 100 VAC line surges
I_F(AV)	1 A - Enables continuous conduction mode operation in sub-15 W isolated flyback or buck-derived converters
V_FM (max)	0.98 V @ 1 A - Reduces conduction loss to ≤0.98 W per diode, lowering thermal stress in compact PCB layouts
t_rr (max)	35 ns - Minimizes switching loss and EMI generation during turn-off in 100–500 kHz topologies
R_th(j-a)	65 °C/W (ceramic board) - Allows ~1.2 W dissipation before reaching 120 °C junction limit with 25 °C ambient
Package	S-FLAT™ - 2.8 × 1.2 × 1.2 mm surface-mount outline compatible with standard reflow profiles and automated placement

Pinout & Package

The CRH01(TE85L) is a two-terminal surface-mount diode in Toshiba's proprietary S-FLAT™ package (JEITA code 3-2A1A), with anode and cathode exposed on opposite ends of the molded body. No internal leads or third terminal exist.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to higher-potential node (e.g., transformer secondary winding or switch node); polarity must match layout silkscreen marking "H1"
Cathode	Forward current exit / reverse-blocking terminal	Connected to output capacitor ground or common return; defines direction of unidirectional conduction and clamping path

Key Features

Feature	Design Value
Ultra-fast recovery	t_rr ≤ 35 ns enables clean turn-off in high-frequency SMPS without tail current-induced losses
Low forward voltage	V_FM = 0.90 V (typ.) @ 1 A reduces conduction loss by ~15% vs. standard FR1 diodes
Thermally robust package	S-FLAT™ offers 65 °C/W R_th(j-a) on ceramic board-ideal for space-constrained power stages
High surge tolerance	I_FSM = 15 A (50 Hz half-sine) withstands inrush and transient overloads without degradation

Equivalent & Alternatives

The following parts are listed as comparable options for similar ultra-fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ROHM RB055LAM-40	V_RRM = 40 V, I_F(AV) = 1 A, t_rr = 30 ns, same SOD-123FL package	Lower voltage rating restricts use to ≤24 V output circuits; unsuitable for 100 VAC-input front-end rectification	Select only when system maximum reverse voltage stays below 30 V and faster recovery is prioritized over voltage margin
Vishay ES1J	V_RRM = 600 V, I_F(AV) = 1 A, t_rr = 35 ns, DO-214AA (SMA) package	Larger footprint increases parasitic inductance; higher V_RRM adds unnecessary cost and capacitance in low-voltage outputs	Prefer for universal-input offline SMPS where 600 V blocking is required; avoid in space-sensitive low-voltage designs

Compared with RB055LAM-40 and ES1J, the CRH01(TE85L) uniquely balances 200 V blocking, 35 ns recovery, and ultra-compact S-FLAT™ packaging-making it optimal for mid-voltage (12–48 V), high-density SMPS where both voltage margin and board area are design constraints.

FAQ

What is the maximum junction temperature rating for CRH01(TE85L)?

The CRH01(TE85L) has a maximum junction temperature (T_j) rating of +150 °C, with recommended derating to ≤120 °C for high-reliability operation. This allows sustained 1 A conduction at elevated ambient temperatures when mounted on a ceramic board with R_th(j-a) = 65 °C/W, as confirmed in Toshiba's absolute maximum ratings table.

Does CRH01(TE85L) have a specified reverse recovery charge (Q_rr)?

No, the official Toshiba datasheet for CRH01(TE85L) does not specify reverse recovery charge (Q_rr). Only reverse recovery time (t_rr ≤ 35 ns) and forward recovery time (t_fr ≤ 100 ns) are provided under defined test conditions (I_F = 1 A, di/dt = −30 A/µs). Designers should rely on t_rr and empirical measurement for EMI estimation.

Is CRH01(TE85L) RoHS compliant and lead-free?

Yes, CRH01(TE85L) is RoHS compliant and lead-free, as confirmed by Toshiba's environmental compliance documentation and material declarations. The device meets EU Directive 2011/65/EU requirements, with homogeneous lead content below 0.1 wt% and no restricted substances above threshold limits.

What is the marking code printed on the CRH01(TE85L) package?

The CRH01(TE85L) is marked with "H1" on its top surface, which is Toshiba's standardized abbreviation code for this part number. This marking is visible under standard optical inspection and aligns with JEITA package code 3-2A1A for S-FLAT™ devices.

Can CRH01(TE85L) be used in place of a Schottky diode in 5 V output SMPS?

CRH01(TE85L) can replace Schottky diodes in 5 V output SMPS only if reverse voltage stress remains ≤200 V and efficiency trade-offs are acceptable. While its 0.98 V V_FM is higher than typical Schottky V_F, its 35 ns t_rr and robust surge rating (15 A I_FSM) offer superior reliability in high-di/dt environments where Schottky leakage or thermal runaway may occur.
