Product details
Overview
SMCJ90CHE3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AB (SMCJ) package, designed for high-energy surge protection on power and signal lines. It features a 90 V stand-off voltage (VWM), 146 V maximum clamping voltage (VC) at 10.3 A peak pulse current (IPPM), and 1500 W peak pulse power dissipation (PPPM) with 10/1000 µs waveform - deployed in automotive ECUs, industrial motor drives, and telecom power supplies.
For engineers reviewing the SMCJ90CHE3/57T datasheet, SMCJ90CHE3/57T pinout, SMCJ90CHE3/57T application, or SMCJ90CHE3/57T equivalent, this device is selected for robust ESD and lightning surge immunity where AEC-Q101 qualification, low incremental surge resistance, and bi-directional clamping symmetry are required in compact surface-mount form.
Technical Context
The SMCJ90CHE3/57T operates as a bi-directional avalanche diode, leveraging glass-passivated junction technology to achieve sub-nanosecond response time and stable breakdown behavior under repetitive transients. Its symmetrical VBR range (100–111 V at 1 mA test current) ensures identical clamping performance in both polarities, critical for AC-coupled or floating bus protection.
Thermally, it exhibits RθJA = 75 °C/W and RθJL = 15 °C/W, enabling reliable operation up to TJ = 150 °C when mounted on 8.0 mm × 8.0 mm copper pads. The device is rated for non-repetitive 8.3 ms half-sine IFSM = 200 A only in uni-directional variants - not applicable here due to bi-directional construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 90 V - Maximum continuous reverse operating voltage before clamping initiates; defines safe working margin for 72–90 V DC systems. |
| VBR min/max | 100 V / 111 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on across production lot and temperature. |
| VC @ IPPM | 146 V at 10.3 A - Clamped voltage during 10/1000 µs surge; limits downstream IC stress to ≤146 V under full-rated transient. |
| PPPM | 1500 W - Peak surge power handling capability; supports IEC 61000-4-5 Level 4 (4 kV line-earth) with appropriate series impedance. |
| ID @ VWM | 1.0 µA - Reverse leakage at stand-off; negligible power loss and signal distortion in high-impedance sensing or bias networks. |
| TJ max. | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments without derating below 125 °C ambient. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC standard; suitable for ASIL-B systems. |
Pinout & Package
SMCJ90CHE3/57T uses the DO-214AB (SMCJ) surface-mount package: molded epoxy case with J-bend leads, 0.320" (8.13 mm) body length, 0.246" (6.22 mm) width, and matte tin-plated terminals compliant with J-STD-002 solderability. Bi-directional devices have no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; clamps voltage above ±100 V in either direction - no orientation required during placement. |
| Case (exposed metal pad) | Thermal & mechanical anchor | Not electrically connected; provides thermal path to PCB copper and mechanical stability - requires unbroken 8.0 mm × 8.0 mm thermal pad per terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional clamping symmetry | Identical VBR (100–111 V) and VC (146 V) in both polarities - eliminates need for polarity-aware layout in AC or differential bus protection. |
| AEC-Q101 qualification | Validated for automotive under-hood use including HTGB, TC, and HTRB - reduces qualification effort for Tier 1 suppliers targeting ISO/TS 16949 compliance. |
| Low incremental surge resistance | Enables tighter VC control under high di/dt surges - improves protection margin for fast-rising transients like EFT (IEC 61000-4-4). |
| MSL Level 1 (260 °C peak) | Compatible with standard lead-free reflow profiles without baking - supports high-volume automated assembly without moisture sensitivity delays. |
| Glass-passivated junction | Stable leakage and breakdown over lifetime - prevents parameter drift in humid or high-temperature industrial environments. |
Applications
| Automotive Power Distribution | Industrial PLC Analog Inputs |
|---|---|
Use Scenario: Protection of 24 V battery-fed ECUs against load dump (ISO 7637-2 Pulse 5a) and alternator transients. IC Role / Device Role / Timing Role: Primary clamping element placed at board entry point before DC-DC converter input. Use Value: Limits transient voltage to ≤146 V while absorbing 1500 W peak energy - prevents MOSFET gate oxide rupture and regulator latch-up. |
Use Scenario: Shielding 4–20 mA current loop inputs from induced surges in factory floor wiring. IC Role / Device Role / Timing Role: Bidirectional shunt protector across input terminals, upstream of precision op-amp front-end. Use Value: Sub-ns response ensures clamping before op-amp input stage saturates; 1.0 µA leakage avoids calibration drift in µA-level measurement circuits. |
| Telecom DC Power Feeds | Motor Drive Gate Driver Supplies |
Use Scenario: Safeguarding -48 V telecom rectifier outputs from lightning-induced surges on long outdoor cable runs. IC Role / Device Role / Timing Role: Secondary protection stage after gas discharge tube (GDT), providing low-clamp refinement. Use Value: 146 V clamping allows use with -48 V systems having ±20 % tolerance (up to -57.6 V), maintaining >100 V safety margin to rail. |
Use Scenario: Protecting isolated gate driver bias supplies (e.g., 15 V) in IGBT inverters from Miller-induced spikes. IC Role / Device Role / Timing Role: Localized clamp across gate supply rails, adjacent to driver IC. Use Value: Symmetric clamping prevents negative voltage undershoot that could forward-bias internal ESD diodes in gate drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90CA-E3/52T (Vishay) | Lower PPPM (600 W), smaller SMB package (DO-214AA), same VWM/VC specs | Reduced surge margin; suitable only for lower-energy threats (IEC 61000-4-5 Level 2) | Select when board space is constrained and system-level surge testing confirms 600 W sufficiency. |
| 1.5KE91A (ON Semiconductor) | Through-hole TO-218 package, higher VF, no AEC-Q101 qualification, 1500 W rating | Requires wave soldering; not qualified for automotive; higher thermal resistance limits sustained surge duty cycle | Choose for cost-sensitive industrial power supplies where AEC-Q101 is unnecessary and manual assembly is acceptable. |
Compared with SMCJ90CHE3/57T, SMBJ90CA-E3/52T trades surge capacity for footprint reduction, while 1.5KE91A sacrifices automotive qualification and thermal performance for legacy through-hole compatibility - making SMCJ90CHE3/57T the optimal choice for AEC-Q101-compliant, high-power-density designs.

FAQ
What is the polarity configuration of SMCJ90CHE3/57T?
The SMCJ90CHE3/57T is a bi-directional TVS diode with symmetrical anode/cathode terminals - no polarity marking is present on the DO-214AB package. It clamps voltage transients equally in both directions, making it ideal for AC-coupled lines or floating buses where polarity cannot be guaranteed during surge events. This behavior is confirmed by identical VBR and VC specifications in both polarities per the Vishay datasheet.
Does SMCJ90CHE3/57T meet automotive qualification standards?
Yes, SMCJ90CHE3/57T carries the HE3 suffix indicating AEC-Q101 qualification - verified through temperature cycling, high-temperature reverse bias (HTRB), and ESD testing per the AEC standard. This makes SMCJ90CHE3/57T suitable for under-hood automotive applications including engine control modules and body electronics where extended temperature operation and long-term reliability are required.
What is the maximum clamping voltage of SMCJ90CHE3/57T under surge conditions?
The maximum clamping voltage (VC) of SMCJ90CHE3/57T is 146 V at 10.3 A peak pulse current (IPPM), measured using the standardized 10/1000 µs double-exponential waveform. This value represents the upper limit of voltage seen by downstream circuitry during a full-rated 1500 W transient event, ensuring protected components remain within their absolute maximum ratings.
How does the DO-214AB package of SMCJ90CHE3/57T affect thermal performance?
The DO-214AB (SMCJ) package of SMCJ90CHE3/57T delivers RθJA = 75 °C/W and RθJL = 15 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. This thermal design enables SMCJ90CHE3/57T to sustain repeated surges without exceeding TJ = 150 °C, provided PCB layout follows Vishay's recommended pad dimensions and copper thickness - critical for automotive and industrial applications with elevated ambient temperatures.
Is SMCJ90CHE3/57T RoHS compliant and halogen-free?
