Product details
Overview
SMA5J10CA-E3/61 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 10 V stand-off voltage (VWM), 11.1–12.3 V breakdown voltage (VBR), 17.0 V clamping voltage (VC) at 29.4 A peak pulse current (IPPM), and 500 W peak pulse power (PPPM) with 10/1000 μs waveform - used to protect automotive sensor interfaces and industrial I/O circuits against ESD and load dump transients.
For engineers reviewing the SMA5J10CA-E3/61 datasheet, SMA5J10CA-E3/61 pinout, SMA5J10CA-E3/61 application, or SMA5J10CA-E3/61 equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM ≈ 1.7), AEC-Q101 qualification eligibility (via HE3 suffix), thermal resistance (RθJA = 80 °C/W), and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with reverse leakage ID ≤ 1.0 μA at 10 V VWM and clamping action triggered above VBR (min 11.1 V). Its glass-passivated junction ensures stable breakdown and fast response (< 1 ns), while low incremental surge resistance enables effective energy diversion during 8.3 ms half-sine or 10/1000 μs transients.
The device is rated for TJ = –55 °C to +150 °C operation, meets MSL Level 1 (260 °C reflow peak), and uses matte tin-plated leads compliant with J-STD-002 and JESD 22-B102. No polarity marking is present on SMA5J10CA-E3/61 due to its bidirectional construction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 10 V - maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected line. |
| VBR (min/max) | 11.1 V / 12.3 V - verified breakdown threshold at 1 mA test current; ensures predictable turn-on across temperature and lot variation. |
| VC @ IPPM | 17.0 V at 29.4 A - clamped voltage during 500 W transient; determines maximum stress imposed on downstream ICs. |
| PPPM | 500 W - peak pulse power handling with 10/1000 μs waveform; supports robust protection against IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | ≤ 1.0 μA - ultra-low reverse leakage at stand-off voltage; minimizes standby power loss and signal distortion. |
| TJ max. | +150 °C - maximum junction temperature; enables reliable operation in under-hood automotive or industrial enclosures. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional configuration with no polarity marking. Case meets UL 94 V-0 flammability rating; terminals are matte tin plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; clamps voltage excursions above ±VBR in either direction - no cathode band or polarity indicator required. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating signal lines without polarity concerns - e.g., CAN bus, RS-485, or sensor differential pairs. |
| Glass-passivated junction | Ensures long-term stability of VBR and low leakage under thermal cycling and humidity exposure - critical for automotive and industrial field life. |
| MSL Level 1 rating | Supports standard Pb-free reflow profiles up to 260 °C peak without preconditioning - simplifies manufacturing and eliminates moisture sensitivity handling. |
| Low clamping ratio (VC/VWM) | 1.7 - delivers tight voltage limiting relative to stand-off level, reducing margin needed for protected IC's absolute maximum ratings. |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting analog output lines of pressure/temperature sensors in engine control units exposed to load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS clamp placed directly at connector entry point to shunt transients before reaching precision ADC front-end. Use Value: Limits induced voltage to ≤17.0 V during 500 W surges, preserving sensor signal integrity and preventing ADC saturation or latch-up. |
Use Scenario: Safeguarding 24 V digital input channels on PLC modules subjected to inductive switching noise from solenoid valves. IC Role / Device Role / Timing Role: Standoff-rated transient suppressor mounted on PCB edge near terminal block to absorb repetitive 10/1000 μs spikes. Use Value: Withstands ≥1000 surges at rated IPPM while maintaining <1.0 μA leakage at 10 V - ensuring stable logic-level recognition over product lifetime. |
| Telecom Line Interface | Consumer USB Port Protection |
Use Scenario: Shielding RS-485 transceivers in base station backhaul links from lightning-induced common-mode surges on twisted-pair cables. IC Role / Device Role / Timing Role: Bidirectional TVS deployed differentially across A/B lines to clamp mode-common transients without disrupting DC bias. Use Value: Symmetric clamping ensures equal voltage excursion on both lines, preserving differential receiver common-mode rejection ratio (CMRR). |
Use Scenario: Adding secondary surge protection on VBUS and D+/D− lines of USB 2.0 ports in smart home hubs exposed to ESD events. IC Role / Device Role / Timing Role: Low-capacitance TVS placed after primary ESD array to handle higher-energy transients beyond IEC 61000-4-2 limits. Use Value: 17.0 V VC prevents damage to USB PHY while RθJA = 80 °C/W allows thermal dissipation without heatsinking in compact enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J10A-E3/61 | Unidirectional version; includes cathode band marking and forward voltage drop (VF = 3.5 V @ 25 A). | Requires polarity-aware layout; unsuitable for AC or floating lines where voltage reversal occurs. | Select only when protecting DC-biased unidirectional signals (e.g., 12 V supply rail) and polarity alignment is guaranteed. |
| SMCJ10CA-E3/73 | Same VWM/VBR/VC specs but in larger SMC (DO-214AB) package; PPPM = 1500 W, RθJA = 30 °C/W. | Higher power handling and lower thermal resistance, but requires 3.5× larger PCB area and different pad layout. | Choose when system-level surge testing exceeds 500 W or ambient temperature exceeds 105 °C - not a drop-in replacement. |
Compared with SMA5J10CA-E3/61, the unidirectional SMA5J10A-E3/61 demands strict polarity routing, while the SMCJ10CA-E3/73 offers triple the power rating at the cost of footprint and thermal design overhead - making SMA5J10CA-E3/61 optimal for space-constrained bidirectional protection at 500 W duty.

FAQ
What is the clamping voltage of SMA5J10CA-E3/61 and how does it protect downstream components?
The SMA5J10CA-E3/61 has a maximum clamping voltage (VC) of 17.0 V at 29.4 A peak pulse current. This value defines the highest voltage that will appear across protected circuitry during a 10/1000 μs transient. By limiting voltage to ≤17.0 V, the SMA5J10CA-E3/61 ensures sensitive components like microcontrollers or transceivers remain within their absolute maximum ratings - preventing latch-up, gate oxide rupture, or permanent damage during surge events.
Is SMA5J10CA-E3/61 suitable for automotive applications?
Yes - SMA5J10CA-E3/61 is RoHS-compliant and part of the AEC-Q101-qualified SMA5J family. While the -E3/61 suffix denotes commercial grade, the base P/NHE3 variant (e.g., SMA5J10CAHE3_A) is fully AEC-Q101 qualified. Engineers selecting SMA5J10CA-E3/61 for automotive use should verify qualification status via Vishay's ordering code matrix and confirm compliance with specific vehicle subsystem requirements.
How does the bidirectional nature of SMA5J10CA-E3/61 affect PCB layout?
The SMA5J10CA-E3/61 has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies layout for AC-coupled or floating lines - such as differential bus interfaces (CAN, RS-485) - where voltage reversals occur naturally. Unlike unidirectional variants, SMA5J10CA-E3/61 avoids risk of incorrect installation and removes need for silkscreen polarity indicators.
What is the thermal resistance of SMA5J10CA-E3/61 and why does it matter?
The SMA5J10CA-E3/61 has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads. This parameter determines how much the junction temperature rises per watt of dissipated surge energy. For repeated transients or high ambient temperatures, adequate copper area is essential to keep TJ ≤ 150 °C - ensuring long-term reliability and avoiding thermal runaway during multi-pulse stress.
Can SMA5J10CA-E3/61 replace SMAJ10CA in an existing design?
No - SMA5J10CA-E3/61 and SMAJ10CA differ in peak pulse power: SMA5J10CA-E3/61 is rated for 500 W, while SMAJ10CA is rated for 400 W. Though both share SMA package and similar VWM/VBR, the higher PPPM of SMA5J10CA-E3/61 provides greater surge margin. Substitution requires validation of thermal performance and clamping behavior under actual system-level transients - SMA5J10CA-E3/61 is not a guaranteed drop-in replacement.
