Product details
Overview
SMA5J16CAHE3_A/H 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 16 V stand-off voltage (VWM), 26.0 V maximum clamping voltage at 19.2 A peak pulse current (IPPM), and 500 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J16CAHE3_A/H datasheet, SMA5J16CAHE3_A/H pinout, SMA5J16CAHE3_A/H application, or SMA5J16CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while the low RθJA of 80 °C/W supports thermal reliability under repetitive surge conditions.
The device complies with ANSI/IEEE C62.35 for transient suppression and meets J-STD-020 MSL Level 1 (260 °C peak reflow). With a maximum junction temperature of 150 °C and -55 °C to +150 °C operating range, it is rated for under-hood automotive environments and industrial control systems requiring robust ESD and lightning surge immunity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 16 V - Maximum continuous reverse voltage before clamping begins; defines safe operating margin below circuit operating voltage. |
| VBR (Breakdown Voltage) | 17.8–19.7 V at 1 mA - Confirmed minimum/maximum breakdown threshold ensuring predictable turn-on during transients. |
| VC (Clamping Voltage) | 26.0 V at IPPM = 19.2 A - Peak voltage seen by protected circuit during 500 W surge; determines stress on downstream ICs. |
| PPPM (Peak Pulse Power) | 500 W (10/1000 μs) - Energy-handling capacity defining survivability against IEC 61000-4-5 Level 4 surges. |
| IR (Reverse Leakage) | 1.0 μA max at VWM - Negligible standby current that avoids signal distortion or battery drain in always-on circuits. |
| TJ max | +150 °C - Enables use in high-temperature automotive and industrial enclosures without derating. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Bidirectional construction means no polarity marking; terminals are symmetrical and interchangeable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals serve identical roles; clamps voltage above ±26.0 V regardless of polarity - eliminates orientation errors during assembly. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces per stress test requirements. |
| Glass passivated junction | Ensures long-term stability of breakdown voltage and leakage current across temperature and humidity cycling. |
| MSL Level 1 (260 °C) | Supports standard lead-free reflow profiles without preconditioning or dry-pack requirements. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a), improving system-level immunity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J16CAHM3_A/H | Halogen-free version of same electrical specs; identical VWM, VC, PPPM, and AEC-Q101 qualification. | Required where halogen-free material compliance (IEC 61249-2-21) is mandated in final product bill-of-materials. | Select SMA5J16CAHM3_A/H when RoHS + halogen-free certification is contractually required; otherwise SMA5J16CAHE3_A/H suffices. |
| SMA6J16CAHE3_A/H | Higher 600 W PPPM rating (vs. 500 W), same VWM/VC, but larger package footprint (SMB/DO-214AA) and higher RθJA (90 °C/W). | Better suited for higher-energy surge environments (e.g., outdoor telecom cabinets) where PCB space permits larger package. | Choose SMA6J16CAHE3_A/H only if 600 W surge margin is needed and SMB layout is available; SMA5J16CAHE3_A/H offers optimal power density for space-constrained designs. |
Compared with SMA5J16CAHE3_A/H, the HM3 variant adds halogen-free compliance without performance trade-offs, while the SMA6J16CAHE3_A/H increases surge capacity at the cost of board area and thermal resistance - making SMA5J16CAHE3_A/H the preferred choice for AEC-Q101-compliant, space-sensitive automotive and industrial applications.

FAQ
What is the clamping voltage of the SMA5J16CAHE3_A/H under maximum surge conditions?
The SMA5J16CAHE3_A/H has a maximum clamping voltage (VC) of 26.0 V when subjected to its rated peak pulse current of 19.2 A using a 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient events. The SMA5J16CAHE3_A/H maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is the SMA5J16CAHE3_A/H suitable for automotive applications?
Yes, the SMA5J16CAHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix "HE3". It meets stress test requirements for temperature cycling, humidity, mechanical shock, and surge endurance relevant to engine control units, body electronics, and ADAS sensor interfaces. The SMA5J16CAHE3_A/H also complies with J-STD-020 MSL Level 1 for lead-free reflow compatibility.
How does the bidirectional configuration of the SMA5J16CAHE3_A/H affect its circuit implementation?
The SMA5J16CAHE3_A/H is bidirectional, meaning it clamps symmetrically for both positive and negative transients - no cathode/anode orientation is required during placement. This simplifies PCB layout for AC-coupled lines, differential buses (e.g., CAN, RS-485), or ungrounded power rails. The SMA5J16CAHE3_A/H achieves this via internal back-to-back diode structure, delivering identical VBR and VC in either direction.
What is the thermal resistance of the SMA5J16CAHE3_A/H, and how does it impact layout design?
The SMA5J16CAHE3_A/H 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 per terminal. This value assumes standard FR-4 PCB with 1 oz copper. To maintain safe junction temperatures under repeated surges, designers must provide adequate copper area and avoid excessive trace length between the SMA5J16CAHE3_A/H and ground/power planes.
Does the SMA5J16CAHE3_A/H meet RoHS and REACH compliance standards?
Yes, the SMA5J16CAHE3_A/H is RoHS-compliant per EU Directive 2011/65/EU and satisfies Vishay's material declaration per REACH SVHC requirements. The "E3" suffix confirms compliance, and the device carries Vishay's standard material categorization documentation (www.vishay.com/doc?99912). No exemptions apply, and lead content is below 0.1 wt%.
